Datasheet
• Compact, rugged, low cost self-contained sensors in metal die cast housings
• Epoxy-encapsulated circuitry; leakproof IP67 (NEMA 6) construcon for harsh environments
• Outstanding electrical noise immunity
• Dual LED system indicates sensor performance
• Choice of integral cable or quick disconnect connector
WARNING: Not To Be Used for Personnel Protecon
Never use this device as a sensing device for personnel protecon. Doing so could lead to
serious injury or death. This device does not include the self-checking redundant circuitry
necessary to allow its use in personnel safety applicaons. A sensor failure or malfuncon can
cause either an energized or de-energized sensor output condion.

To order the 9 m (30 ) cable models, add the sux "W/30" to the model
number of any cabled sensor (for example, QM42VN6D W/30). Models
with a QD connector require a mang cable.
Specicaons
Sensing Beam
Infrared, 880 nm for opposed and diuse
Visible red, 660 nm for ber opc and retroreecve modes
Supply Voltage and Current
10 to 30 V dc (10% maximum ripple) at less than:
Diuse and retroreecve models: 20 milliamps
Opposed mode: 30 milliamps (emier), 10 milliamps (receiver)
Fiber opc models: 30 milliamps
Supply Protecon Circuitry
Protected against reverse polarity and transient voltages
Output
Conguraon
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 emier's)
modulated light
Dark operate: N.C. output conducts when the sensor sees dark
Output Rang
100 mA maximum (each output)
O-state leakage current: < 5 microamps at 30 V dc
On-state saturaon voltage: < 1 V at 10 mA dc; < 1.5 V at 100 mA dc
Repeatability
Diuse and retroreecve modes: 250 microseconds
Opposed Mode: 120 microseconds
Fiber opc mode: 60 microseconds
Adjustments
All models except emiers: 15-turn sloed brass GAIN (sensivity) adjustment
potenometer (clutched at both ends of travel)
Indicators
Two LEDs: green and amber
Green solid = power to sensor is on (Opposed
emiers: Green power "on")
Green ashing = output is overloaded
Amber solid = light is sensed; normally open output on
Amber ashing = marginal excess gain (1–1.5x) in light condion
Construcon
Housings are die-cast zinc alloy with black epoxy powder paint nish; lenses are acrylic
Connecons
2 m (6.5 ) or 9 m (30 ) aached cable, or 4-pin Euro-style quick-disconnect ng;
Cables for QD models are purchased separately
