E2C/E2C-H

Cable Lengths for Sensor-Amplifier Unit Combinations

Standard Models

Note: The standard cable length is 3 m. Models with 5-m or 10-m are manufactured upon order.

* Refer to page 14 for the operation of cable length switching.

Heat-resistant Models

Note: The standard cable length is 3 m. Models with 5-m are manufactured upon order.

Self-diagnostic Function

The self-diagnostic output transistor will turn ON in the following cases. (The output will turn ON for any of these conditions individually.)

(1) Sensor open circuit: Transistor will turn ON the instance there is an open circuit for the Sensor (including the cable).

(2) Detection:

The output will turn ON if a sensing object is within 93% to 100% of the sensing distance continuously for 0.3 s or longer (e.g.,

for sensing object position offset).

(3) No detection: The output will turn ON if a sensing object is within 100% to 107% of the sensing distance continuously for 0.3 s or longer (e.g.,

when background is influencing detection).

Indicators

• The detection indicator lights when a sensing object approaches the

sensing distance to indicate that a sensing object has been detected.

• The stability indicator lights when the sensing object approaches within

93% of the sensing distance or moves away from 107% of the sensing

distance to indicate a stable sensing or non-sensing condition.

* The self-diagnostic output may turn ON if the sensing objects moves a low

speed. In actual application, include an ON-delay timer circuit or other

suitable measure.
