Sensing Range
30 to 300 mm (1.2" to 11.8")
Supply Voltage
10 to 30V dc (10% maximum ripple); 65 mA max. (exclusive of load), 40 mA typical @ 25V input
Ultrasonic Frequency
300 kHz, rep. rate 2.5 ms
Supply Protection Circuitry
Protected against reverse polarity and transient voltages
Output Configuration
Analog Output: 0 to 10V dc or 4 to 20 mA, depending on model
Output Protection
Protected against short circuit conditions
Output Ratings
Analog Voltage Output: 2.5 kΩ minimum load resistance
Analog Current Output: 1 kΩ max @ 24V input
For current output (4-20 mA) models, ideal results are achieved when the total load resistance
R = [(Vin – 3)/0.020]Ω. Example, at Vin = 24V dc, R ≈ 1 kΩ (1 watt). A worst-case shift of 1% of sensing
distance is caused by operating the sensor at Vin = 30V dc and R = 0 Ω.
Output Response Time
2.5 milliseconds: Black wire at 5-30V dc
(for a 95% step change)
30 milliseconds: Black wire at 0-2V dc (or open)
Consult factory for other response speed options
Delay at Power-Up
300 milliseconds
Temperature Effect
0.02% of distance/ °C
Linearity*
2.5 ms response: ±1 mm
Resolution*
2.5 ms response: 1 mm
Minimum Window Size
5 mm
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 (see page 3).
Indicators
Range Indicator (Red/Green)
Teach/Output Indicator (Yellow/Red)
Remote TEACH Input
Impedance: 12 kΩ
Construction
Threaded Barrel: Thermoplastic polyester
Push Button: Santoprene
Operating Conditions
Temperature: -20° to +60° C (-4° to +140° F)
Connections
2 m (6.5') or 9 m (30') shielded 5-conductor (with drain) PVC jacketed attached cable or 5-pin
Euro-style quick-disconnect (see page 10 for quick-disconnect cable options)
Environmental Rating
Leakproof design is rated IEC IP67; NEMA 6P
Vibration and Mechanical
All models meet Mil. Std. 202F requirements method 201A (vibration: 10 to 60 Hz max., double amplitude
Shock
0.06", maximum acceleration 10G). Also meets IEC 947-5-2 requirements: 30G 11 ms duration, half sine
wave.
Temperature Warmup Drift
Less than 1.7% of sensing distance upon power-up (see Temperature Compensation, page 2)
Application Notes
Objects passing inside the specified near limit may produce a false response.
Certifications
* Linearity and resolution are specified using a 50 mm x 50 mm (2" x 2") aluminum plate at 22°C under fixed sensing conditions.
