The Omron EE-SPWL411 is a through-beam photomicrosensor with a 1 m sensing range, listed as active in Omron's current lifecycle. It outputs NPN, operates Light-ON, and accepts 5 to 24 VDC supply.
The 1 m through-beam range is the maximum detection distance between emitter and receiver under clean conditions. With a supply voltage spanning 5 to 24 VDC, this sensor can run directly off a 24 VDC panel supply or a 5 VDC logic rail without conversion. Light-ON logic means the NPN output sinks current when the beam path is clear.
