The Omron EE-SX670-WR 1M is a through-beam slot-type photoelectric sensor with a 5 mm gap. It uses an NPN open-collector output, switching at 35 mA max, and runs on a 5 V supply. The 1 ms response time suits moderate-speed object detection — think conveyor presence, door position, or part-pass sensing in packaging lines. The -25°C to 55°C operating range covers most indoor industrial cabinets but not freezers or unheated outdoor sheds.
5 mm slot — what it means for the mount
The 5 mm sensing distance is the slot width: a 5 mm gap between the emitter and receiver arms. Objects passing through must be at least a few mm thick to reliably break the beam. The chassis-mount body needs a bracket or panel cutout; the 1 m cable (the 'WR 1M' suffix) gives enough reach to a nearby terminal block or PLC input card.
