Cabled models are shown. Quick disconnect wiring diagrams are functionally identical. ## Specifications Sensing Beam Infrared, 880 nm for opposed and diffuse Visible red, 660 nm for fiber optic and retroreflective modes Supply Voltage and Current 10 to 30 V DC (10% maximum ripple) at less than: Diffuse and retroreflective models: 20 milliamps Opposed mode: 30 milliamps (emitter), 10 milliamps (receiver) Fiber optic models: 30 milliamps Supply Protection Circuitry Protected against reverse polarity and transient voltages Output Configuration SPDT (complementary) solid-state dc switch; Choose NPN (current sinking) or PNP (current sourcing) models. Light operate: N.O. output conducts when the sensor sees its own (or the emitter's) modulated light Dark operate: N.C. output conducts when the sensor sees dark Repeatability Diffuse and retroreflective modes: 250 microseconds Opposed Mode: 120 microseconds Fiber optic mode: 60 microseconds Adjustments All models except emitters: 15-turn slotted brass GAIN (sensitivity) adjustment potentiometer (clutched at both ends of travel) Indicators Two LEDs: green and amber Green solid = power to sensor is on (Opposed emitters: Green power "on") Green flashing = output is overloaded Amber solid = light is sensed; normally open output on Amber flashing = marginal excess gain (1–1.5x) in light condition Construction Housings are die-cast zinc alloy with black epoxy powder paint finish; lenses are acrylic Connections 2 m (6.5 ft) or 9 m (30 ft) attached cable, or 4-pin M12 quickdisconnect fitting; Cables for QD models are purchased separately Output Rating 100 mA maximum (each output) Off-state leakage current: < 5 microamps at 30 V DC On-state saturation voltage: < 1 V at 10 mA DC; < 1.5 V at 100 mA DC Output Protection Circuitry Protected against false pulse on power-up and continuous overload or short-circuit of outputs Overload trip point ≥ 150 mA, typical, at 20 °C Output Response Time Diffuse and retroreflective modes: 1 millisecond on and off Opposed mode: 1 millisecond on, 0.5 millisecond off Fiber optic mode: 0.25 millisecond on and off Environmental Rating IP67 Operating Conditions Temperature: –20 °C to +70 °C (–4 °F to +158 °F) Relative Humidity: 90% at +50 °C maximum relative humidity (noncondensing) **==> picture [30 x 5] intentionally omitted <==** **----- Start of picture text -----**
