Product Specifications
Sensing Beam
Adjustments
All models have a 15-turn slotted brass cutoff distance adjustment potentiometer
(clutched at both ends of travel)
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
Output Rating
100 mA maximum (each output)
Off-state leakage current: <5 microamps at 30V dc;
On-state saturation voltage: <1V at 10 mA dc; <1.5V 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
≥
150mA, typical, at 20ºC
Output Response Time
1 millisecond on and off
NOTE: 100 millisecond delay on power-up; outputs are non-conducting during this time
Indicators
Two LEDs: Green and Yellow
GREEN glowing steadily
= power to sensor is "on"
GREEN flashing
= output is overloaded
YELLOW glowing steadily = light is sensed; normally open output "on"
YELLOW flashing
= marginal excess gain (1-1.5x) in light condition
Repeatability of Response
250 microseconds
Construction
Housings are die-cast zinc alloy with black acrylic polyurethane finish; lenses are acrylic
Environmental Rating
IP67; NEMA 6
Connections
2 m (6-1/2 ft) or 9 m (30-ft) attached cable, or 4-pin euro-style quick-disconnect fitting; Cables for QD
models are purchased separately
Operating Temperature
-20º to +55ºC (-7º to 130ºF); Maximum relative humidity 90% at 50ºC (non-condensing)
Visible Red, 680 nm
Supply Voltage and Current
10 to 30V dc (10% maximum ripple) at less than 50 milliamps
Sensing Hysteresis
Less than 7% of set cutoff distance
