Sensor

(side view)

A reflective background object in this position or moving across the

sensor face in this axis and direction may cause a false sensor

response.

Specifications

Sensing Beam

Infrared, 880 nm

Supply Voltage and Current

10 to 30 V dc (10% max. ripple) at less than 40 mA

Supply Protection Circuitry

Protected against reverse polarity and transient voltages

Output Configuration

SPDT (complementary) solid-state dc switch; choose NPN or PNP

models

Light operate: N.O. output conducts when the sensor sees its own

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 30 V dc

ON-state saturation voltage: < 1 V at 10 mA dc; < 1.5 V 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 ≥ 150 mA, typical, at 20 ºC

Output Response Time

1 millisecond on and off

NOTE: 100 millisecond delay on power-up;

outputs are non-conducting during this time

Repeatability of Response

250 microseconds

Sensing Hysteresis

Less than 5% of cutoff distance - 2000 mm models

Less than 4% of cutoff distance - 1500 mm models

Less than 3% of cutoff distance - 1000 mm models

Less than 2% of cutoff distance - 750 mm models

Less than 1% of cutoff distance - 500 mm models

Cutoff Point Tolerance

±10% of nominal cutoff distance

Range

50 mm (2.0 in) to cutoff point

10 mm (0.4 in) to 6 m (20 ft)

Indicators

Two LEDs: Green and Amber

Green on steady = power to sensor is ON

Green flashing = output is overloaded

Amber on steady = light is sensed; normally open output ON

Amber flashing = marginal excess gain (1-1.5x) in light condition

Construction

Housings are die-cast zinc alloy with black acrylic polyurethane finish;

lenses are acrylic

Environmental Rating

IEC IP67

NEMA 6

Connections

2 m (6.5 ft) or 9 m (30 ft) attached cable, or 4-pin M12/Euro-style

quick-disconnect fitting; cables for QD models are purchased

separately

Operating Conditions

−20 °C to +55 °C (−4 °F to +131°F)

90% at +50 °C maximum relative humidity (non-condensing)

Required Overcurrent Protection

WARNING: Electrical connections must be

made by qualified personnel in accordance

with local and national electrical codes and

regulations.

Overcurrent protection is required to be provided by end product

application per the supplied table.

Overcurrent protection may be provided with external fusing or via

Current Limiting, Class 2 Power Supply.

Supply wiring leads < 24 AWG shall not be spliced.
