DC Product Specifications

Sensing Beam

Adjustments

All models except emitters: 15-turn slotted brass GAIN (sensitivity) 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

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

Indicators

Two LEDs: Green and Yellow

GREEN glowing steadily

= power to sensor is "on"

Opposed emitters: Green power "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

Diffuse and retroreflective modes: 250 microseconds
Opposed Mode: 120 microseconds
Fiber optic mode: 60 microseconds

Construction

Housings are die-cast zinc alloy with black epoxy powder paint 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 +70ºC (-7º to 158ºF); Maximum relative humidity 90% at 50ºC (non-condensing)

Infrared, 880 nm for opposed and diffuse; Visible red, 660 nm for fiber optic and retroreflective modes

Supply Voltage and Current

10 to 30V 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
