Slot sensor with a PNP output — what that means for your input card
The Omron EE-SX671P is a through-beam slot sensor with a 5 mm gap and a PNP open-collector output. It runs on a 5 V supply and switches up to 12 mA with a 1 ms response time. If your PLC or controller input card expects PNP (sourcing) logic, this sensor connects directly — no pull-up resistor or level shifter needed. The narrow slot is sized for flag detection, edge counting on thin webs, or position verification of small parts; it will not cover a wide object presence zone.
Active lifecycle — no last-time-buy pressure
The EE-SX671P is listed as Active in production. It can be specified into new BOMs without near-term end-of-life risk.
Mounting and wiring — chassis-mount, no connector
Chassis-mount package with wire leads — no connector. The 5 V supply rail must be clean; switching transients can couple into the 1 ms response window.
