Small Light Curtain, 6/8/10/20/30 Beam, NPN/PNP

SUCH small light curtain is a compact safety light curtain sensor for short-distance machine guarding and industrial automation. It supports 10mm/20mm/40mm beam spacing, 6–34 beams, ≤10ms response time, DC24V power supply, and NPN/PNP/Relay output. It is suitable for machine builders, automation engineers, and factory maintenance teams in assembly lines, automated equipment, and production line safety protection.

Feature

• CPU Self-Test: The light curtain uses CPU self-testing. When the light curtain itself malfunctions, it ensures that it does not send erroneous signals to the controlled equipment, thus guaranteeing the safety of the light curtain.
• Superior Anti-Interference Capability: Utilizing infrared communication and a dedicated optical system, it has strong anti-interference capabilities and is highly resistant to electromagnetic signals, strobe lights, welding arcs, and ambient light sources.
• Power-on Delay Function: The light curtain sensor only allows the equipment to operate normally after a 3-second power-on delay, providing a buffer time for operators and equipment, thus improving the safety of both.
• EDM Function: When the output signal of a small light curtain needs to be connected to a standard relay/contactor device, to ensure the safety of the entire system, the safety light curtain has an EDM function that monitors the "external relay contact status" to prevent the loss of safety protection functions due to external relay contact sticking faults.
