    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.

    Designed Safety Light Curtain
    We need to place some safety light curtains in our warehouse to ensure the safety of the logistics handling process. We first purchased a few to test whether they were suitable. Does this safety light curtain have a reset function or reset the external switch to insert the relay module wiring?

    ATO Responded
    Sorry, the safety light curtain does not have a reset switch. The sensor is only used to detect the signal. It outputs a signal after detecting an obstacle, and then you can control the relay based on this signal. The specific control method also needs to be designed according to the application requirements.
    I need 6 kits of safety curtains
    Hi, I need 6 kits of safety curtains 24vdc npn no output 48 inches, and the space between each beam average of 5 inches.
    I need to 2 kits 24 inches and 5 inches between each beam.

    This safety light curtain can meet your needs.
    Response time of safety light curtain
    What is the least response time for your safety light curtain?
    From: Amberl | Date: 17/12/2021
    Was this review helpful? Yes No (0/0)
    ATO Responded
    It can reach 5ms.
    This response time is related to the height of the grating, the distance of optical axis, the number of beams, and the detection length.
    Good safety light curtain manufacture
    After receiving, I can feel the safety light curtain has good quality just from its elegant color shell. The safety light curtain installation is simple. The setting is fast. It has passed all the safety testing already. I think it is right to choose ATO as our safety light curtain manufacture.
