SA1U Photoelectric Switches Wide variations such as universal voltage and DC power types, available with time delay. Maximum sensing range of 50m (through-beam). Universal voltage types operate on 24 to 240V AC and 12 to 240V DC. DC power types operate on 12 to 24V DC. Washable IP67 Four sensing methods: through-beam, polarized retro- reflective, diffuse-reflective, and background suppression. Adjustable time delay: 0.1 to 5 seconds Mounting hole centers: 40, 50 to 55 mm Operation and stable LED indicators. SPDT contact for relay output type. Transistor output type has NPN and PNP open collector dual outputs. Interference prevention allows two units to be mounted in close proximity (except through-beam model). Spring-up terminal block structure enables easy wiring. Wiring can be extended to up to 100m using 8 to 10 mm round cables.
