Output Configuration	Analog models: Voltage sourcing: 0 to 10V dc Current sourcing: 4 to 20 mA
	Dual-discrete models: Dual PNP or NPN, selectable using DIP switch
Output Ratings	Analog Voltage Output: 0 to 10V dc
		Minimum load resistance = 500 Ω
		Minimum required supply voltage for full 0-10V output span = ( 1000 + 13)V dc
			RLOAD
	Analog Current Output: 4 to 20 mA
		Maximum load resistance = 1 kΩ or ( V supply - 5 ) Ω, whichever is lower
			0.02
		Minimum required supply voltage for full 4-20 mA output span = 10V dc or
		[(RLoad x 0.02)+5]V dc, whichever is greater. 4-20 mA output calibrated at 25° C with
		250 Ω load.
	Discrete Output: 150 mA max.

		PNP: less than 1.2V @ 10 mA; less than 1.65V @ 150 mA
Temperature Effect	Uncompensated: 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 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 p/n 70137 (Analog) and p/n 110112 (Discrete)
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 cables are ordered separately.
	See pages 415 and 421.
Operating Conditions	Temperature: -20° to +70° C		Relative humidity: 100%
Vibration and	All models meet Mil Std. 202F requirements. Method 201A (vibration: 10 to 60Hz max.,
Mechanical Shock	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 specified near limit (200 mm ) may produce a false response
	•	For best accuracy, allow 30 minute warm-up before programming or operating
