Hall effect magnetic proximity sensor can achieve the largest detection distance with a small switch volume. It can detect magnetic objects (usually permanent magnets), and then generate a trigger switch signal output. Since the magnetic field can pass through many non-magnetic objects, this triggering process does not necessarily require the target object to be directly close to the sensing surface of the magnetic proximity switch, but the magnetic field is transmitted to a long distance through a magnetic conductor.

The rotary encoder is a device used to measure the speed and cooperate with PWM technology to realize rapid speed regulation. The photoelectric rotary encoder can convert the angular displacement, angular velocity and other mechanical quantities of the output shaft into corresponding electrical pulses through photoelectric conversion. output (REP). Divided into single output and dual output. The technical parameters mainly include the number of pulses per revolution (dozens to thousands), and the power supply voltage. Single output means that the output of the rotary encoder is a set of pulses, while the rotary encoder with double output outputs two sets of pulses with phase A/ B difference of 90 degrees. Through these two sets of pulses, not only the speed can be measured, but also the rotation can be judged direction.

A contactor is an electrical appliance that uses a current flowing through a coil to generate a magnetic field to close the contacts to complete the control of the load. As a kind of contactor, the AC contactor also controls the load, but there is an additional precondition on the original basis. The AC current flows through the coil. AC contactors have been widely used at present, high performance lighting contactors and 1 pole - 4 pole definite purpose contactors are popular AC contactors.

Centrifugal pump refers to a pump that transports liquid by the centrifugal force generated by the rotation of the impeller. Centrifugal pumps are widely used and are almost indispensable equipment in process systems. The small size, simple operation and long service life of the centrifugal pump are the outstanding advantages of the centrifugal pump. If the pipeline delivery system is regarded as the vascular circulation system of the human body, then the centrifugal pump is equivalent to the heart that transports blood.

Proximity sensor is a new type of integrated switch, which is an ideal electronic switch sensor. It has a lot of advantages, including small size, fast frequency response, wide voltage range, strong anti-interference ability, high repositioning accuracy, high operating frequency, reliable operation, long life, low power consumption, corrosion resistance, vibration resistance and adaptability to harsh working environments. What’s more, there will be no friction during the use of the proximity sensor, and will not increase the torque of each sensed element.

The inverter converts DC power (battery, storage battery) into AC power (usually 220V 50Hz sine or square wave). In general, an inverter is an electronic device that converts low voltage (12, 24, 48 volts, etc.) DC power into 220V AC (or other voltages) power. It consists of an inverter bridge, control logic and filter circuit. In daily life, 220 volt alternating current is usually rectified into direct current for use, and the inverter is the opposite. We are in an era of "mobile", mobile office, mobile communication, mobile leisure and mobile entertainment. In the mobile living state, not only the low-voltage direct current supplied by the battery or the battery is required, but also the alternating current which is indispensable in the daily environment. The inverter is to meet our needs.

DC reversing contactor is a switching appliance suitable for remote manipulation (closing, opening or switching) of high-power electrical appliances. The contactor is used in electric vehicles, and the coil consumes a large amount of power, which is generally used for intermittent duty. DC contactors are mainly used for making and breaking DC circuits at a long distance and frequently starting, stopping, reversing and reversing braking DC motors, and also for frequently connecting and disconnecting lifting electromagnets, solenoid valves, clutches electromagnetic coils, etc.

When the brushed DC motor is working, the coil and the commutator rotate, but the magnetic steel and the carbon brush do not rotate. The alternating change of the current direction of the coil is accomplished by the commutator and the carbon brush that rotate with the motor. Compared with brushless motors, brushed motors have fewer wires, just one positive and one negative wire. If the BDC motor needs to be reversed, just switch the position of the two wires and it will be done.

A DC-DC converter is a power supply or electromechanical device which can convert a direct current (DC) power source from one level to another. Its power can range from very small (small power source) to very large (high voltage power conversion). Some DC-DC converters have the same reference point for the output voltage and input voltage, while some DC-DC converters have the output voltage isolated from the input voltage.

A circular connector is a type of electromechanical component used to make or break an electric circuit. These multi-pin connectors are basically cylinder-shaped and feature a circular mating surface designed for connection. What does its inner structure looks like? How do we disassemble it for wiring? What benefits could it bring to us? Where are they applied? This blog will lead you to the answers.

A portable vibration meter is a simple instrument that can measure the vibration displacement, vibration velocity, and vibration acceleration of the equipment. It is generally used for equipment inspection. The portable vibration meter is small in size, light in weight and compact in structure. The instrument integrates the functions of multi-channel vibration acquisition, infrared temperature measurement and laser speed measurement, which not only meets the requirements of portable acquisition, but also realizes powerful on-site Data acquisition and machine failure analysis functions.

There are two and three positions for toggle switch operation. Three button switch and a certain side of the position is not positioned, etc. At the same time, its connection circuit types are also more. There are many kinds of button handles for toggle switches, such as metal conical knob handle, plastic conical knob handle, fluorescent knob handle, plastic sleeve knob handle, spherical knob handle, flat bar knob handle, lock bar knob handle, wave knob handle, paddle knob handle, etc. Lock lever handle is suitable for dangerous operation. There are "promote unlock" type knob handle, which is provided with a spring, screw mouth end milling groove. The operator must first lift the knob handle and then push it to another position to ensure safe work.

A centrifugal pump is a mechanical device designed to move fluid by transferring rotational energy from one or more driven rotors, called impellers. Fluid enters the rapidly rotating impeller along its axis and exits through the impeller's blade tips along its circumference by centrifugal force. The action of the impeller increases the velocity and pressure of the fluid and directs it towards the pump outlet. The pump casing is specially designed to compress the fluid from the pump inlet, direct it to the impeller, and then slow and control the fluid before discharging.

Vacuum contactor is a device that can withstand multiple operations (strong mechanical life). It can cut off the load current at the same time, but can not break the short-circuit current. The vacuum contactor has two contacts, normally open and normally closed, and does not have the function of short-circuit current protection. When a given signal is received, it can perform separation and hold actions. Analogus to ordinary home circuit, VCB is like a circuit breaker at home inside a panel and VC is a relay in our any of instruments at home.

What exactly is the difference between incremental and absolute encoders? An absolute encoder can tell you the exact position of the shaft in its rotation at any given time (and how many rotations have transpired on a multi-turn absolute encoder). An incremental encoder can only report a change in position. It may not sound like a big difference, but it's night and day if the system has a loss of power. Once power is restored, an absolute encoder can report exact position without any movement. An incremental encoder will need to find an Index or home position before it can do so – and if it doesn't have an index, it won't be able to tell you it's position at all.

Rotary switch is a multi - loop control appliance which is made up of several contact components of the same structure. It consists of operating mechanism, positioning device, contact, contact system, rotating shaft, handle and other components. The contact is in the insulating base, double breakpoint contact bridge structure, the moving contact is designed to automatically adjust to ensure the synchronization of on-off, static contact is installed in the contact seat.
