Product Specifications

Supply Voltage and Current	10 to 30V dc (10% max. ripple) Diffuse, Retroreflective and Fiber Optic:Less than 25 mA (exclusive of load) Opposed Emitters and Receivers:draw 20 mA each
Range	Opposed:8 m Polarized Retroreflective (clear object):100 mm to 2 m, range is specified using one model BRT-3 retroreflector Diffuse (long range):800 mm Diffuse (short range):200 mm Convergent:50 mm Plastic Fiber Optic:Range varies by sensing mode and fiber optics used
Supply Protection Circuitry	Protected against reverse polarity and transient voltages
Output Configuration	Solid-state complementary (SPDT) dc switch:NPN (current sinking) or PNP (current sourcing), depending on model. The dark operate (DO) output may be wired as a normally open marginal signal alarm output, depending upon hookup to the power supply.
Output Rating	150 mA max. each output in standard hookup; when wired for alarm output, the total load may not exceed 150 mA OFF-state leakage current:Less than 1 µA @ 30V dc Output saturation voltage:less than 1V @ 10 mA dc; less than 1.5V @ 150 mA dc
Output Protection Circuitry	Protected against false pulse on power-up, transient voltages, and continuous overload or short circuit of outputs
Output Response Time	Response time is independent of signal strength. FPY High-Speed Plastic Fiber Optic:100 microseconds ON/OFF All other:1 milliseconds ON/OFF
Delay at Power-up	100 milliseconds; outputs do not conduct during this time.
Repeatability	Repeatability is independent of signal strength. Opposed:0.13 milliseconds Retroreflective and Diffuse:0.25 milliseconds FPY High-Speed Plastic Fiber Optic:25 microseconds
Adjustments	SENSITIVITY control (single-turn, o-ring sealed potentiometer)
Indicators	2 LED Indicators (except Emitters): Green ON steady:dc power is ON Green flashing:output overload Yellow ON steady:light-operate (LO) output is energized Yellow flashing:marginal excess gain (1-1.5x), LO output is energized 1 LED Indicator (Emitters only): Green ON steady:power is ON
Construction	Completely sealed yellow and black ABS housing, with acrylic lenses. Stainless-steel mounting bracket and M3 mounting hardware are supplied.
Environmental Rating	Meets NEMA standards 1, 2, 3, 3S, 4, 4X, 6, 12 and 13; IEC IP67. Housing materials rated UL 94 V-0
Connections	PVC-jacketed 4-conductor 2 m or 9 m cables, or 150 mm pigtail with threaded 4-pin Pico-style quick-disconnect fitting. QD cables are ordered separately.
Operating Conditions	Temperature:-20° to +55° C Relative humidity:90% @ 50° C (non-condensing)
Application Notes	To avoid damage to the sensor caused by static discharge (ESD), use the plastic screwdriver supplied with each sensor (included in the hardware packet) to adjust the SENSITIVITY control. Otherwise, use a screwdriver with an insulated handle.
