WARNING . . .

Not To Be Used for Personnel Protection

Never use these products as sensing devices for personnel protection. Doing so could lead to serious injury or death.

These sensors do NOT include the self-checking redundant circuitry necessary to allow their use in personnel safety
applications. A sensor failure or malfunction can cause either an energized or de-energized sensor output condition. Consult your current
Banner Safety Products catalog for safety products which meet OSHA, ANSI and IEC standards for personnel protection.

Sensing Beam

Adjustments 4-turn slotted 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 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 ≥130mA, 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

Certifications Approvals in process

Construction Housings are die-cast zinc alloy with black acrylic polyurethane finish; lenses are acrylic
Environmental Rating IP67; NEMA 6

Connections 2 m (6.5') or 9 m (30') attached cable, or 4-pin Euro-style quick-disconnect fitting; Cables for QD models

are purchased separately

Operating Temperature -20º to +55ºC (-4º to +131ºF); Maximum relative humidity 90% at 50ºC (non-condensing)

Sensing Hysteresis Less than 20% of set sensing distance

Infrared, 880 nm

Supply Voltage and Current 10 to 30V dc (10% maximum ripple) at less than 40 milliamps
