Overview
- Specially designed EZ-BEAM style optics and electronics for reliable sensing without adjustments
- 20-250V ac with SPST solid-state output
- 18 mm plastic threaded barrel sensor
- Available in opposed, polarized and non-polarized retroreflective, diffuse and fixed-field sensing modes
- Dual-LED multi-function indicators for monitoring sensor performance
Product Specifications
| Supply Voltage and Current | 20 to 250V ac (50/60 Hz)
Average current:20 mA Peak current:200 mA @ 20V ac, 500 mA @ 120V ac, 750 mA @ 250V ac |
|---|---|
| Range | Opposed:20 m Non-polarized Retroreflective:2 m, range is specified using one model BRT-3 retroreflector Polarized Retroreflective:2 m, range is specified using one model BRT-3 retroreflector Diffuse (long range):300 mm Diffuse (short range):100 mm Fixed-field:0-25, 0-50 or 0-100 cutoff, depending on model |
| Supply Protection Circuitry | Protected against transient voltages |
| Output Configuration | SPST solid-state ac switch; three-wire hookup: Light operate (LO) or dark operate (DO), depending on model
Light operate:Output conducts when the sensor sees its own (or the emitter’s) modulated light Dark operate:Output conducts when sensor sees dark |
| Output Rating | 300 mA max. (continious); Fixed-field derate 5 mA/° C above +50° C
Inrush capability:1 A for 20 milliseconds, non-repetitive OFF-state leakage current:less than 100 µA ON-state voltage drop:3V @ 300 mA ac; 2V @ 15 mA ac |
| Output Protection Circuitry | Protected against false pulse on power-up |
| Output Response Time | Response time is independent of signal strength.
Opposed:16 milliseconds ON; 8 milliseconds OFF Polarized retroreflective, Non-polarized Retroreflective, Diffuse and Fixed-field:16 milliseconds ON/OFF |
| Delay at Power-up | 100 milliseconds |
| Repeatability | Repeatability is independent of signal strength.
Opposed:2 milliseconds Polarized Retroreflective, Non-polarized Retroreflective, Diffuse and Fixed-field:4 milliseconds |
| Indicators | 2 LED Indicators:Green and Yellow Green ON steady:power to sensor is ON
Yellow ON steady:sensor sees light
Yellow flashing:marginal excess gain (1-1.5x) in light condition
|
| Construction | Thermoplastic polyester housing with polycarbonate or acrylic lenses. Two jam nuts are included with each sensor. |
| Environmental Rating | Leakproof design rated NEMA 6P; DIN 40050 (IP69K) |
| Connections | 2 m or 9 m attached cable, or 4 pin Micro-style quick-disconnect fitting. QD cables are ordered separately. |
| Operating Conditions | Temperature:-40° to +70° C Relative humidity:90% @ 50° C (non-condensing) |
| Vibration and Mechanical Shock | All models meet Mil. Std. 202F requirements. Method 201A (Vibration; frequency 10 to 60 Hz, max, double amplitude 0.06-inch acceleration 10G). Method 213B conditions H&I (Shock: 75G with unit operating; 100G for non-operation) |
