T18U Series Sensor
Specifications
Sensing Range
Normal Resolution: 600 mm (24")
High Resolution: 300 mm (12")
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.
Supply Voltage
12 to 30V dc (10% max. ripple)
Supply Current
50 mA (emitters); 35 mA (receivers), exclusive of output load
Receiver Output Configuration
NPN (sinking) or PNP (sourcing), depending on model; Normally Open (NO) and Normally Closed (NC)
(complementary)
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: < 1.5V at 10 mA; < 2.0V at 150 mA
OFF-state leakage current: < 1 microamp at 30V dc
Output Protection Circuitry
Protected against overload and short circuit conditions. No false pulse upon receiver power-up.
Delay at Power-up
100 milliseconds
Output Response Time
Normal Resolution Mode: 2 milliseconds ON and OFF
High Resolution Mode: 1 millisecond ON and OFF
Rep Rate
Normal Resolution Mode: 125 Hz max.
High Resolution Mode: 200 Hz max.
Mechanical Sensing
Repeatability at 300 mm (12")
Range
Normal Resolution Mode: < 2 mm (< 0.08")
High Resolution Mode: < 1 mm (< 0.04")
Beam Angle (-3dB full angle)
15 ± 2°
Indicators
Emitters have a Green LED for Power ON.
Receivers have one Green Power LED and one Yellow Signal LED.
Green Power LED: ON indicates power on
Flashing indicates output overload
Yellow Signal LED: sonic signal received (flash rate is proportional to received signal strength; flash is from full to
half intensity)
Construction
Patented T-style yellow PBT housing with black PBT
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.
Connections
Emitter: 2 m (6.5') attached PVC-covered 2-wire cable or 4-pin Euro-Style quick disconnect fitting
Receiver: 2 m (6.5') attached PVC-covered 4-wire cable or 4-pin Euro-Style quick disconnect fitting
9 m (30') cables available by request. A model with a QD connector requires a mating cable; see page 4.
Environmental Rating
NEMA 6P, IEC IP67.
Operating Conditions
Temperature: -40° to +70°C (-40° to +158° F)
Vibration and
Mechanical Shock
All models meet Mil. Std. 202F requirements method 201A (vibration: 10 to 60 Hz max. double amplitude 0.06",
max. acceleration 10G) and method 213B conditions H & I (Shock: 75G with unit operation: 100G for non-operation)
Also meets IEC 947-5-2; 30G, 11 ms duration, half sine wave.
