Safety Light Curtain

The safety light curtain is composed of a light emitter and a light receiver, which can effectively detect any opaque objects exceeding the detection accuracy entering the light curtain area. The safety light curtain adopts a separate design of the light curtain and the controller. It can be used in conjunction with the controller, or directly connected to PLC and safety relays, and cooperate with the machine tool control system to realize the automatic shutdown function in dangerous situations. ATO can provide AC 110-220V controller according to customer needs. When the safety protection device fails, ensure that the safety light curtain will not send wrong signals to the controlled equipment.

Application: The safety light curtain is an advanced laser sensor used to protect workers around dangerous machinery and equipment. It can be applied to paper cutters, conveyors, assembly lines, woodworking machinery, leather machinery, forging presses, punching and shearing machines, presses, milling machines, drilling machines, welding machines, CNC, elevators, automation equipment, handling equipment and soon.

Tips: How to select safety light curtains?

1. Protection height: It is the protection height of the dangerous area. It is based on what kind of mechanical equipment the customer will use. For example, the punching machine has a large tonnage and the protection height needs to be larger.
2. Distance of optical axis: Refers to the distance between the transmitting tubes of safety light curtain, the shorter the distance, the smaller the test object, the higher the safety factor. Generally 10mm distance is enough to protect fingers, 20mm distance is enough to protect palm, 40mm distance is enough to protect arm.
3. The number of beams: Safety light curtain beam has the same protection height. When in same protection height, the greater the number, the smaller distance of optical axis, the smaller objects, the higher security. In general, the number of beams is a decisive factor for pricing the safety light curtain.
4. Dimensions: The commonly dimension is 30*30mm, using for punching machine and other equipments.
5. Output mode: There are five general output modes, such as NPN output, PNP output, relay output, digital output and analog output. It is to be set based on customer requirements.
6. Installation: Steel pipe support installation and side-mounted mode.
