■Characteristics (Ta = –10°C to 65°C)

Object: N8.5 Munsell paper with a reflection factor of 70%.

Note: 1. Distance from the mounting reference plane.

2. “Sensitivity” is defined as “inclination of divided output line” and the variation value between individual products of fluctuating divided out-

put voltage per unit length.

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.

3. 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.

4. 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.)

tions of use which apply to the Product. This information by itself is not

sufficient f or a complete determination of the suitability of the Product i n combi-

nation with the end product, machine, system, or other application or use.

Buyer shall be solely responsible for determining appropriateness of the partic-

ular Product with respect to Buyer's application, product or system. Buyer

shall take application responsibility in all cases but the following is a non-

exhaustive list of applications for which particular attention must be given:

(i) Outdoor use, uses involving potential chemical contamination or electrical

interference, or conditions or uses not described in this document.

(ii)Energy control systems, combustion systems, railroad systems, aviation

systems, medical equipment, amusement machines, vehicles, safety

equipment, and installations subject to

separate industry or government regulations.

(iii)Use in consumer products or any use in significant quantities.

(iv)Systems, machines and equipment that could present a risk to life or

property. Please know and observe all prohibi tio ns of use appli ca ble to this

product.

re-

late it to actual application requirements. Actual performance is subject

Seller's Warranty and Limitations of Liability.
