    • Both AC and DC operation in a single unit
    • Short circuit protected solid-state outputs on AC/DC and DC-only versions (except thru-beam)
    • Relay output option provides 3 Amp current switching on AC/DC models
    • Thru-beam models feature an infrared sensing beam along with a visible red LED behind the lens in the source unit to aid in sensor alignment
    • Fiber optic sensors operate in thru-beam or diffuse reflective mode depending on the fiber optic cable selected
    • Glass fiber optic cables plug into NEMA 4 rated sockets on the front of the sensor. Sockets are leakproof even when the fiber optic cables are not plugged in
    • Fully potted construction for use in areas subject to washdown, high shock and/or vibration
    • Choice of pre-wired power cable or built-in mini-connector versions. Standard pre-wired cable length is 6 feet (1.8m)
