Indicators
Range Indicator (Red/Green) and Teach/Output In-
dicator (Yellow/Red)
Range Indicator: Green - Target is within sensing
range; Red - Target is outside sensing range; OFF -
Sensing Power is OFF
Teach/Output Indicator: Yellow - Target is within
taught limits; OFF - Target is outside taught window
limits; Red - Sensor is in TEACH mode
Adjustments
Sensing Window Limits: TEACH-mode programming of
near and far window limits may be set using the push
button or remotely via TEACH input
Construction
ABS housing, TPE Push Button, ABS Push Button
housing, Polycarbonate lightpipes
Connections
2 m (6.5 ft) or 9 m (30 ft) 4-conductor PVC jacketed at-
tached cable, or 4-pin Euro-style integral QD (Q8), or
4-pin Pico-style integral QD (Q7), or 4-pin Euro-style
150 mm (6 in) pigtail QD (Q5), or 4-pin Pico-style 150
mm (6 in) pigtail QD (Q)
Environmental Rating
Leakproof design, rated NEMA 6P; IEC IP67 or IP68
depending on model; UL Type 1
Operating Conditions
Temperature: −20 to +60 °C (−4 to +140 °F)
Relative Humidity: 100% (non-condensing)
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
See Temperature Compensation on page 2
Application Notes
1. If supply voltage is > 24V dc, derate maximum out-
put current 5 mA/°C above 50°C.
2. NPN off-state leakage current is < 200 µA for load
resistances > 3 kΩ or optically isolated loads. For load
current of 100 mA, leakage is < 1% of load current.
3. Objects passing inside the specified near limit may
produce a false response.
