Output and wiring
NPN open collector, Dark-ON means the output transistor turns on (pulls low) when the reflected beam is blocked. Wire the collector to the PLC input with a pull-up resistor to 5 V; the emitter goes to ground. Solder-mount package — no connector, so plan for a small PCB or terminal block on the bracket.
Lifecycle and sourcing
Active lifecycle — no end-of-life notice on this line. Still a standard catalog item, so no last-time-buy scramble. Sourced and quoted to order against an RFQ through independent distribution; availability and current pricing confirmed at quote time.
