E3S-C

Characteristic data (typical)

Nomenclature:

(Horizontal type)

(Vertical type)

*1. The output transistor can be selected with the NPN/PNP output selector.

*2. The operation mode can be selected with the L/OND/ON selector.

Note: The through-beam and retroreflective models are different in sensitivity

adjuster shape.

Operation

Sensitivity adjustment (diffuse reflective model, light-ON)

Unlike the conventional models, the E3S-C scarcely has sensitivity variations between products. Therefore, you need to make the

above adjustment on only one diffuse reflective model of E3S-CD that will be used for detection under the same conditions, and

match the indicator points of the other diffuse reflective models of E3S-CD with the above adjusted one. (You need not match the

sensitivity of each sensor.)

Adjustment procedure

A Point A

Place a sensing object in the predetermined position, turn the

sensitivity adjuster clockwise (increase sensitivity) until the

incident indicator (red) is turned ON, and define this position

as (A).

B Point B

Remove the sensing object, turn the sensitivity adjuster fur-

ther clockwise until the incident indicator (red) is turned ON

by a background object, and define this position as (B). Turn

the sensitivity adjuster counterclockwise (decrease sensitivi-

ty) from (B) until the incident indicator (red) is turned OFF,

and define this position as (C). When there is no background

object, define the maximum adjuster position (Max) as (C).

C Setting

---

Set the adjuster in the middle of positions (A) and (C) (opti-

mum sensitivity setting). Also make sure that the stability in-

dicator (green) is turned ON when there is an object and

when there is no object.

When the indicator is not turned ON, recheck the detection

method since there is a little allowance.
