Operating Conditions

Temperature: −20 °C to +70 °C (−4 °F to +158 °F)
Maximum Relative Humidity: 100%

Connections

2 m (6.5 ft) or 9 m (30 ft) shielded 5-conductor (with drain) PVC

jacketed attached cable or 5-pin Micro-style quick-disconnect or 5-pin

Mini-style quick-disconnect fitting.

Environmental Rating

Leakproof design is rated IEC IP67; NEMA 6P

Vibration and Mechanical Shock

All models meet Mil Std. 202F requirements. Method 201A (vibration:

10 to 60 Hz max., double amplitude 0.06", maximum acceleration

10G). Also meets IEC 947-5-2 requirements: 30G 11 ms duration, half

sine wave.

Temperature Warmup Drift

Less than 1.0% of sensing distance upon power-up with Temperature

Compensation enabled

Application Notes

Objects passing inside the specified minimum sensing distance (200

mm) may produce a false response.
