    1. With complete specifications and models, the safety light curtain is easy to install and has simple wiring
    2. Light curtain sensor has perfect self-inspection function and strong anti-electromagnetic and optical interference ability.
    3. Strong vibration resistance, excellent waterproof and dustproof performance.
    4. The curtain sensor’ NC series output NPN/PNP signal, RC series is equipped with a plug-in controller, which adopts double relay output, and LED indicates working and fault status.
    5. Configurable S-shaped external controller provides double-sided protection.
    6. Laser safety curtain’ aluminum alloy shell, protects the internal circuit of the grating when it is impacted.
    7. Anti-vibration rubber ring, and shock-absorbing pad double protection, effectively reduce the vibration caused by impact.


    1. The safety grating is a transistor output, which cannot directly control the on-off
    2. Control on and off requires a controller or relay (optional)
    3. NPN normally closed NC output low-level OV under normal light-on state, no output when blocking light
    4. NPN usually opens NO no output under normal light-on state, block light output low-level 0V
    5. PNP normally closes NC
    6. Output high-level 24V in the normal light-through state, no output when light is blocked
    7. PNP usually opens NO output under normal light-on state, block light output high-level 24V.

    Tips: Why does the punch press require a safety light curtain to protect safety?

    1. Because mechanical equipment must be installed with safety gratings according to certain safety requirements, the main purpose is safety protection.
    2. Automatic equipment or mechanical automation operation requires manual assistance, so during mechanical operation or operation, people need to avoid sources of danger and stay in a safe area (an area where people will not be injured). When a person enters a dangerous area, the machine should stop or take some other response measures. When the person evacuates from the dangerous area, the machine receives the signal and makes a follow-up response.

    Very nice for the price easy to install and works perfect. We installed this machine in horizontally on the floor and it works nice as a no step area while our machine is running
