QT50U DC Speciﬁcations

Linearity (Analog Models)

+/- 0.2% of span from 200 to 8000 mm; +/- 0.1% of span from 500 to 8000 mm (1 mm minimum)

Resolution/Repeatability

1.0 mm

Hysteresis

5 mm

Output Response Time

Analog models: 100 to 2300 milliseconds

Dual-discrete models: 100 to 1600 milliseconds

Minimum Window Size

20 mm

Adjustments

Sensing window limits: TEACH-Mode programming of near and far window limits may be set using the push buttons or remotely

using TEACH input.

Indicators

Green Power ON LED: Indicates power is ON

Red Signal LED: Indicates target is within sensing range, and the condition of the received signal.

TEACH/Output indicator (bicolor Yellow/Red):

Yellow–Target is within taught limits Yellow OFF (Discrete)–Target is outside taught window limits

Red–Sensor is in TEACH mode Yellow Flashing (Analog)–Target is outside taught window limits

Remote TEACH

See data sheet

Construction

Transducer: Ceramic/Epoxy composite Housing: ABS/Polycarbonate

Membrane Switch: Polyester Lightpipes: Acrylic

Environmental Rating

Leakproof design is rated IEC IP67; NEMA 6P

Connections

2 m or 9 m shielded 5-conductor (with drain) PVC jacketed attached cable, or 5-pin Euro-style quick-disconnect or 5-pin Mini-style

quick-disconnect. QD cordsets are ordered separately. See page 312.

Operating Conditions

Temperature: -20° to +70° C Relative humidity: 100%

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

Temperature Warmup Drift

Less than 0.8% of sensing distance upon power-up with Temperature Compensation enabled

Application Notes

• Objects passing inside the specied near limit (200 mm ) may produce a false response

• For best accuracy, allow 30 minute warm-up before programming or operating

Min. voltage and current: 5V dc, 10 mA

Mechanical life of relay: 50,000,000 operations

Electrical life of relay at full resistive load: 100,000 operations

NOTE: Transient suppression is recommended when switching inductive loads.

Temperature Effect

Uncompensated: 0.2% of distance/° C Compensated: 0.02% of distance/° C

Repeatability

1.0 mm
