T18U Specifications
Sensing Range
(no minimum range)
NORMAL resolution mode: to 600 mm
HIGH resolution mode: to 300 mm
Supply Voltage and Current
12 to 30V dc, 10% max. ac ripple.
50 mA (emitters); 35 mA (receivers), exclusive of output load.
Ultrasonic Frequency
230 kHz
Minimum spacing
(adjacent pairs)
50 mm for emitter-to-receiver separations of up to 150 mm.
Add 10 mm of adjacent-pair spacing for every 100 mm of emitter-to-receiver spacing beyond 150 mm.
Receiver Output
Configuration
T18VN models: NPN sinking, NO and NC (complementary)
T18VP models: PNP sourcing, NO and NC (complementary)
Receiver Output Rating
150 mA max. each output at 25° C, derated to 100 mA at 70° C (derate ≈ 1 mA per ° C).
Both outputs may be used simultaneously.
ON-state saturation voltage: less than 1.5V at 10 mA; less than 2.0 V at 150 mA
OFF-state leakage current: less than 1 µA at 30V dc
Output protection: Overload and short-circuit protected.
No false pulse upon receiver power-up: false pulse protection causes a 100 millisecond delay upon power-up.
Output Response Time
NORMAL resolution mode: 2 milliseconds ON/OFF
HIGH resolution mode: 1 millisecond ON/OFF
Rep Rate
NORMAL resolution mode: 125 Hz max.
HIGH resolution mode: 200 Hz max.
Mechanical Sensing
Repeatability at 300 mm range
NORMAL resolution mode: less than 2 mm
HIGH resolution mode: less than 1 mm
Beam Angle (-3dB full angle)
15 ± 2˚
Indicators
Emitters have a green LED for dc power ON. Receivers have two LED’s, one yellow and one green.
Green: power ON
Yellow: sonic signal received (ash rate is proportional to received signal strength; ash is from full to half intensity).
See data sheet for detailed information.
Construction
T-style yellow PBT polyester housing with black PBT polyester back cover. Transducer housing is threaded M18 x 1. Mating jam nut is
supplied for mounting. Acoustic face is epoxy reinforced. Circuitry is epoxy-encapsulated.
Environmental Rating
IEC IP67; NEMA 6P
Connections
Emitters: 2 m long attached PVC- covered 2-wire cable or 4-pin Euro-style quick-disconnect tting.
Receivers: 2 m long attached PVC-covered 4-wire cable or 4-pin Euro-style quick-disconnect tting.
9 m long cables are available by request.
Mating Euro-style quick-disconnect cordsets are also available. See page 331.
Operating Temperature
-40° to +70° C
Vibration and
Mechanical Shock
All models meets Mil.Std 202F requirements method 201A (Vibration: frequency 10 to 60 Hz, max., and double amplitude 0.06",
maximum acceleration 10G) and method 213B conditions H&I (Shock: 75G with unit operation; 100G for non-operation).
Also meets IEC 947-5-2 requirements: 30G, 11 milliseconds duration, half sine wave.
