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
