Mounting

Retroreflectlve Sensors

NOTE:

To avoid unwanted trigger signals, make sure that there are no

objects other than the substrate that pass between the emitter/receiver

and the reflector during line operation.

NOTE:

Make sure that the emitter/receiver and reflector are mounted

no more than 7

(2.13 m) from each other {polarized model)

more than

15ft

{4.5

from each other {non-polarized model).

Check the intended mounting position to ensure that there is enough

space

mount the sensor(s) and bracket(s). See Figure 3.

11,

Figure 3.12, and Figure 3.13

Check the intended mounting position

make sure that there are no

objects other than the substrate that

will pass between the sensor

and substrate during

line operation.

3. Locate the emitter/receiver bracket so that it is no further from the

reflector than

a. 7

(2.13 m) for the polarized model,

15ft

(4.5

for the non-polarized model.

Securely connect the emitter/receiver bracket

the mounting

surface. Excessive movement

vibration can result in

intermittent

lse operation caused by loss

alignment

the

substrate.

5. Using the two mounting bolts provided with the bracket, secure the

emitter/receiver to the bracket (Figure 3.13).

Secure the reflector to the mounting surface opposite the

emitter/receiver.

Route

the

sensor leads through water-tight conduit (for an lP-54

enclosure rating) and the strain

relief connector and into the PC40.
