SM91RANQD

The SM91EN/RN series rugged powerful VALU-BEAM® opposed mode Emitter/Receiver Pairs designed to function in difficult environments. Excess gain is conservatively rated at 100x at an emitter-to-receiver separation distance of 3m (10ft). Receivers will not false-trigger when pointed directly into a light source of 120,000lux. Receivers are also immune to false triggering by sunlight reflected from water droplets and interference from flashing strobe lights as are typically found on plant lift trucks. Sensors are also immune to interference from a 5W handheld transceiver, operating on specified frequencies, held 6 inches away from the sensor. Emitters and receivers that are to be used together must carry the same modulation code designation (A, B or C). These sensors are ruggedly constructed in reinforced, moulded, PBT polyester housings with replaceable acrylic lenses.

• Opposed mode sensing to 30m (100ft)
• Choice of three modulation codes enables adjacent sensor pairs to operate without crosstalk
• Three-wire operation (2-wire emitters)
• Solid-state bipolar outputs, 150mA maximum (continuous)
• sinking or sourcing hook-up (usable simultaneously)
• Totally encapsulated circuitry in a rugged, moulded, plastic housing
• Rated NEMA 6P (IEC IP67)
