Product Specifications
Sensing Beam
Adjustments Diffuse models (only); single-turn, top-mounted SENSITIVITY control for adjustment of system gain (turn
clockwise to increase)
Supply Protection Circuitry Protected against reverse polarity
Output Configuration SPST solid-state dc switch;
Choose NPN (current sinking) or PNP (current sourcing) models
Choose light operate (N.O.) or dark operate (N.C.) models
Output Rating 150 mA maximum
Off-state leakage current: <10 microamps at 30V dc;
On-state saturation voltage: <0.5V at 10 mA dc; <1.5V at 150 mA dc
Output Protection Circuitry Protected against false pulse on power-up and continuous overload or short-circuit of outputs
Overload trip point ≥220mA, typical, at 20ºC
Output Response Time Opposed mode: 8 ms "on", 4 ms "off"; Diffuse mode: 3 ms "on" and "off"
Indicators Opposed mode receivers and diffuse mode sensors have two LEDs: Green and Yellow
GREEN glowing steadily = power to sensor is "on"
GREEN flashing = output is overloaded
YELLOW glowing steadily = light is sensed
YELLOW flashing = marginal excess gain (1-1.5x) in light condition
Emitters have one Green LED to indicate when power to sensor is "on"
Repeatability Opposed mode: 1.0 ms; Diffuse mode: 0.75 ms
Construction Housings are black ABS; Rated UL 94V0
Lenses are hermetically-sealed glass; lens covers are clear acrylic
Circuitry is epoxy-encapsulated and completely sealed
Stainless steel M2.5 mounting hardware is included
Environmental Rating
Connections 2 m (6-1/2 ft) attached cable, or 3-pin pico-style quick-disconnect fitting;
Cables for QD models are purchased separately
Operating Temperature -40º to +70ºC (-40º to 158ºF); Maximum relative humidity 90% at 50ºC (non-condensing)
Infrared, 880 nm
Supply Voltage and Current 10 to 30V dc (10% maximum ripple); Emitter or receiver: 15 mA; Diffuse models: 20 mA
(exclusive of load)
