T30UX Specifications
Output Ratings
Discrete output models: 100 mA max.
OFF-state leakage current: NPN: < 200 µA @ 30V dc (see NOTE 1) PNP: < 10 µA @ 30V dc
ON-state saturation voltage: NPN: < 1.6V @ 100 mA PNP: < 3V @ 100 mA
Analog output models:
Analog Voltage Output: 2.5 kΩ min. load resistance
Minimum supply for a full 10V output is 12V dc (for supply voltages between 10 and 12, V out max. is
at least V supply -2)
Analog Current Output: 1 kΩ max. @ 24V input; max. load resistance = (Vcc-4)/0.02Ω
For current output (4-20 mA) models, ideal results are achieved when the total load resistance R = [(Vin – 4)/0.020]Ω. Example, at
Vin = 24V dc, R ≈ 1 kΩ (1 watt)
Output Protection Circuitry
Protected against short circuit conditions
Output Response Time
“A” suffix models: 45 milliseconds
“B” suffix models: 92 milliseconds
“C” suffix models: 135 milliseconds
Delay at Power-up
500 milliseconds
Temperature Effect
0.02% of distance/º C
Linearity (analog models)
0.25% of distance
Repeatability/Resolution

Environmental Rating
Leakproof design, rated IEC IP67 (NEMA 6)
Connections 2 m or 9 m shielded 4-conductor (with drain) PVC cable, 150 mm PUR Euro-style pigtail (QPMA), or 4-pin integral Euro-style
connector (Q8). QD cordsets ordered separately. See page 325.
Operating Conditions
Temperature: -40° to +70° C Relative humidity: 95% at 50°C non-condensing
Vibration and
Mechanical Shock
All models meet Mil. Std. 202F requirements. Method 201A (Vibration: 10 to 60Hz max., double amplitude 0.06", maximum
acceleration 10G). Also meets IEC 947-5-2 requirements: 30G, 11 milliseconds duration, half sine wave.
Application Notes
The temperature warmup drift upon power-up is less than 1% of the sensing distance.
