- Popular, compact MINI-BEAM package with a SPDT electromechanical (E/M) relay
- Available in opposed, polarized and non-polarized retroreflective, diffuse and divergent diffuse, convergent, and glass or plastic fiber optic sensing modes
- 18 mm threaded barrel or side mounting options
Product Specifications
| Supply Voltage and Current | 24 to 240V ac, 50/60 Hz or 24 to 240V dc (1.5 watts or 2.5 VA max.) |
|---|---|
| Range | Opposed (long range):30 m Opposed (short range):3 m Non-polarized Retroreflective:5 m, range is specified using one model BRT-3 retroreflector Polarized Retroreflective:10 mm to 3 m, range is specified using one model BRT-3 retroreflector Diffuse:380 mm Divergent Diffuse:130 mm Convergent:16 or 43 mm, depending on model Plastic and Glass Fiber Optic:Range varies by sensing mode and fiber optics used |
| Supply Protection Circuitry | Protected against transient voltages. DC hookup is without regard to polarity. |
| Output Configuration | SPDT (Single-Pole, Double Throw) (form C) electromechanical relay, ON/OFF output |
| Output Rating | Max. switching power (resistive load):90W, 250VA Max. switching voltage (resistive load):250V ac or 30V dc Max. switching current (resistive load):3 A Min. voltage and current:5V dc, 10 mA Mechanical life:20,000,000 operations Electrical life at full resistive load:100,000 operations |
| Output Protection Circuitry | Protected against false pulse on power-up |
| Output Response Time | Closure time:20 milliseconds max. Release time:20 milliseconds max. Max. switching speed:25 operations per second |
| Repeatability | 1 millisecond |
| Adjustments | Light/Dark-operate select switch and 15-turn slotted brass screw sensitivity (Gain) adjustment potentiometer, clutched at both ends of travel. Both controls are located on rear panel of sensor and protected by a gasketed, clear acrylic cover. |
| Indicators | Alignment Indicating Device system (AID) lights a rear-panel mounted red LED indicator whenever the sensor sees a light condition, with a superimposed pulse rate proportional to the light signal strength (the stronger the signal, the faster the pulse rate). |
| Construction | Reinforced thermoplastic polyester housing, totally encapsulated, o-ring sealing, acrylic lenses and stainless-steel screws |
| Environmental Rating | NEMA 1, 2, 3, 3S, 4, 4X, 6, 12 and 13; IEC IP67 |
| Connections | PVC-jacketed 5-conductor 2 m or 9 m cables. Opposed-mode emitter cables are 2-conductor. |
| Operating Conditions | Temperature:-20° to +55° C Relative humidity:90% @ 50° C (non-condensing) |
| Application Note | Install transient suppressor (MOV) across contacts switching inductive loads. |
