- Available in opposed, polarized retroreflective and fixed-field sensing modes
- Marginal gain indicator with alarm output
- Dual-LED multi-function indicators for monitoring sensor performance
Product Specifications
| Supply Voltage and Current | 10 to 30V dc (10% max. ripple)
Opposed Emitters:25 mA (exclusive of load) Opposed Receivers:20 mA (exclusive of load) Polarized Retroreflective:30 mA (exclusive of load) Fixed-field:35 mA (exclusive of load) |
|---|---|
| Range | Opposed:20 m Polarized Retroreflective:2 m, range is specified using one model BRT-3 retroreflector Fixed-field:0-25, 0-50 or 0-100 mm cutoff, depending on models |
| Supply Protection Circuitry | Protected against reverse polarity and transient voltages |
| Output Rating | 150 mA max. (each); the total load may not exceed 150 mA
OFF-state leakage:less than 1 µA @ 30V dc ON-state saturation voltage:less 1V @ 10 mA dc; less than 1.5V @ 150 mA dc |
| Output Configuration | Sensing Output:PNP (current sourcing), light operate Alarm Output:PNP (current sourcing), normally open and conducts whenever the sensor's excess gain drops to 1-1.5x in light condition |
| Output Protection Circuitry | Protected against false pulse on power-up and continuous overload or short-circuit of outputs |
| Output Response Time | Response time is independent of signal strength
Opposed:3 millisecond ON; 1.5 milliseconds OFF Polarized Retroreflective and Fixed-field:3 milliseconds ON/OFF |
| Delay at Power-up | 100 milliseconds; outputs do not conduct during this time. |
| Repeatability | Repeatability is independent of signal strength
Opposed:375 microseconds Polarized Retroreflective and Fixed-field:750 microseconds |
| Indicators | 2 LED Indicators:Green and Yellow Green ON steady:power to sensor is ON
Green flashing:output is overloaded
Yellow ON steady:normally open output is conducting
Yellow flashing:marginal excess gain (1-1.5x) in light condition
|
| Construction | Thermoplastic polyester housing with polycarbonate or acrylic lenses. One jam nut is included with each sensor. |
| Environmental Rating | Leakproof design is rated NEMA 6P; IEC IP67 |
| Connections | 4-pin Euro-style quick-disconnect fitting. QD cables are ordered separately. |
| Operating Conditions | Temperature:-40° to +70° C Relative humidity:90% @ 50° C (non-condensing) |
