  1. 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.
