Electrical and Optical Characteristics (Ta = -10ºC to 65ºC)

Item	Symbol	Rated value	Remarks
Supply voltage	VCC	5 VDC± 10%	Ripple (p-p): 10 mV p-p max.
Output voltage	OUT	0.2 VDC to (VCC-0.3)V	(see note 1)
Response time	tr	100 µs max.	(see note 2)
LED pulse light emission control signal	PLS	3.5 VDC to VCC	(see note 3)

Note:	1.	Load impedance (between OUT-GND) is set at more than 10 kΩ.
	2.	The time for output voltage to rise from 10% to 90% of the full output range.
	3.	Apply the voltage ranging from 3.5 V to Vcc on the LED pulse light emission control signal terminal. In this case, a maximum of 2 mA (TYP 1 mA) current is sunk.

Characteristics (Ta = -10ºC to 65ºC)

Item	Value
Operating area (see note 1)	6.5 ± 1 mm
Sensitivity variation (see note 2)	-1.4 mV/µm ±10% max.
Resolution (see note 3)	±10 µm max. (Ta = 25ºC)
Linearity (see note 4)	2% F.S. (full scale) max.

Note:

Distance from the mounting reference plane.

"Sensitivity" is defined as "inclination of divided output line" and the variation value between individual products of fluctuating divided output voltage per unit length.

Sensitivity =

(mV/µm)

Where	V0:	Output voltage when d=5.5 mm
	V2:	Output voltage when d=7.5 mm
	d:	Distance from reference mounting plane to an object.

Value of electrical noise range of divided output signal converted to distance under the following conditions.

(1)	Ripple noise of power supply: 10 mV p-p max.
(2)	Sampling time of the sample and hold circuit: 50 µsec
(3)	Distance to object: Distance from the reference mounting plane is 6.5 mm± 1 mm ** When the testing conditions are deviated from the above conditions, resolution changes. For details, please consult OMRON sales representative.

The peak-to-peak value of the output error from the ideal line.
Calculation, based on a linearity of 2% F.S., is as follows:

(1)	The conversion value based on the full scale distance: 2 mm × 0.02 = 0.04 mm (40 µm)
(2)	The conversion value based on the output voltage: 1.4 mV/µm × 40 µm = 56 mV (When the product sensitivity variation is 1.4 mV/ µm)
