- Series positioning and model (with lead wire = WR suffix) The EE SX67 series is a small U-groove transmissive photoelectric switch from OMRON, available in both connector type and lead wire type (WR, with lead wire); the latter directly features a 3-core flexible lead wire, making on-site wiring more convenient and providing better protection.

No object: Infrared light directly reaches the receiving end → light input ON (output is turned on).
Object entering the slot: The light beam is blocked → Shading OFF (output disconnected); it can be switched to Shading ON via dialing.

IV. Features of Wired (WR) 1.3 Direct 3-conductor wiring: Brown = V+, Blue = GND, Black = OUT, no plug required, quick wiring.
- Flex-resistant wire: suitable for frequent movement/vibration scenarios, with less risk of core breakage.
- Integrated protective cover: The connection between the wire and the shell is reinforced to prevent oil and water ingress, ensuring a longer lifespan.
- Small size (approximately 2.3g): Fix with M3 screws, align the slot and install.
- Main functions: 1. Object presence/absence detection: presence/absence of paper, labels, workpieces, and stoppers.
- In place / Limit / Home: equipment limit, home positioning, material level monitoring.
- High-speed counting/speed measurement: With the rotating shield, it has a 1kHz response, suitable for assembly lines and motor speed measurement.
- Broken wire/stall alarm: Detection of broken wires, materials, and chains, as well as stalls.
- Door status/safety protection: Small equipment door switch, safety door interlock.
