(exclusive of load) Dual-discrete models: 10 to 30V dc (10% max. ripple); 100 mA max. @ 10V, 40 mA @ 30V (exclusive of load) Ultrasonic Frequency 75 kHz, rep. rate 96 milliseconds Supply Protection Circuitry Protected against reverse polarity and transient overvoltages Output Protection Protected against short circuit conditions Delay at Power-up 1.5 seconds Output ConfigurationAnalog models: Voltage sourcing: 0 to 10V dc Current sourcing: 4 to 20 mA Dual-discrete models: Dual PNP or NPN, selectable via DIP switch; 150 mA., max. Temperature EffectUncompensated: 0.2% of distance/° C Compensated: 0.02% of distance/° C 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 TimeAnalog models: 100 to 2300 milliseconds Dual-discrete models: 100 to 160 milliseconds Minimum Window Size 20 mm AdjustmentsSensing 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 OFF –Target is outside taught window limits
MEASUREMENT & INSPECTION Red –Sensor is in TEACH mode Remote TEACH See data sheet p/n 70137 (Analog) and p/n 110112 (Discrete) ConstructionTransducer: 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 industrial drain) PVC jacketed attached cable, or 5-pin Euro-style quick-disconnect or 5-pin Mini-style quick-disconnect. QD cables are ordered separately. See pages 382 and 388. Operating ConditionsTemperature: -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 0.890% of sensing distance upon power-up with Temperature Compensation enabled Application Notes • Objects passing inside the specified near limit (200 mm ) may produce a false response• For best accuracy, allow 30 minute warm-up before programming or operating Certifications Hookup DiagramsAnalog Models: MI11 (p. 494) Discrete Models : MI10 (p. 494)
