Operation

■AMPLIFIER SWITCH SETTINGS

Operation Mode

NC Output transistor is ON when the

NO sensor detects a sensing object.

NC Output transistor is OFF when the

NO sensor detects a sensing object.

Cord Length Compensation

3 m Set to 3 m when the length of the

5 m sensor cable is 3 m long.

3 m Set to 5 m when the length of the

5 m sensor cable is 5 m long.

Note: 1. Use the caution label to prevent improper operation after sensitivity adjustment.

2. The mounting bracket is not required when DIN-track mounting.

3. Cord: 4.5 dia. (OD), 4-conductor, vinyl-insulated round cord, standard length: 2 m (6.45 ft)

(It is possible to extend the cord up to 200 m using an independent metal conduit).

Installation

Do not tighten the nut with excessive force. A washer must

be used with the nut.

Effects of Surrounding Metal

When mounting the E2C-H within a metal panel, ensure that the

clearances giv en in the f ollowing tab le are maintained. Failure to

maintain these distances may cause deterioration in the

performance of the sensor.

Model Torque

E2C-X1R5AH 20 kgf • cm (17.3 in-lbs)

E2C-X2AH 60 kgf • cm (52 in-lbs)

E2C-X5AH 150 kgf • cm (130 in-lbs)

Note: The above torque values apply when you use a

toothed washer with the nut that you tighten.

Mutual Interference

When installing two or more E2C-H sensors f ace to face or side

by side, ensure the minimum distances given in the following

table are maintained.

Mounting

Mount the front panel to a DIN track or mounting bracket first,

and then mount the rear part. The mounting brack et is provided

with the E2C-H.

Removal

You can remove the E2C-H b y pulling the yellow grip rail on the

lower part of the rear panel with a flat-blade screwdriver.

Miscellaneous

Do not expose the sensor to steam or install it in places where

water ma y be sprayed because the sensor is not water resistive.

Do not cut or extend the sensor cord or the sensor will not

maintain its characteristics.

After you adjust the sensing distance, apply the caution label

(provided with the E2C-H) to the amplifier and cov er the surface

of the sensitivity adjuster hole.
