The Omron EE-SX672-WR 1M is a through-beam optical sensor with a 5 mm slot, NPN open-collector output, and 5 V supply. It is a chassis-mount slot sensor used for position detection, edge sensing, and object presence in industrial automation, packaging machinery, and assembly lines. The 1 ms response time suits moderate-speed applications like conveyor gate detection or part-present sensing.
Output and wiring
NPN open-collector output sinks up to 35 mA. Wire it to a PLC digital input with a pull-up resistor to the 5 V rail; the output goes low when the beam is interrupted. The 1 m cable (WR 1M suffix) is pre-attached — no connector to source separately.
Supply and environment
Runs on a 5 V supply, common in 5 V logic systems and many PLC input cards. Operating temperature range is -25°C to 55°C — fine for indoor industrial cabinets but not for outdoor or high-heat zones near ovens. Store the reels dry; bulk packaging means no moisture-barrier bag, so keep them in a low-humidity bin.
