Notes
Keep the tape free from stress. If it is
pressed too much, its capability may
deteriorate.
Do not cut the tape.
It will deteriorate the sensing
performance.

Sensor mounting
bracket
MS-EX20-1
Back angled mounting bracket for front sensing type sensor
(The thru-beam type sensor needs two brackets.)
MS-EX20-2
Foot angled mounting bracket for side sensing type sensor
(The thru-beam type sensor needs two brackets.)
MS-EX20-3
L-shaped mounting bracket for front sensing type sensor
(The thru-beam type sensor needs two brackets.)
MS-EX20-4
Back angled mounting bracket for side sensing type sensor
(The thru-beam type sensor needs two brackets.)
Universal sensor
mounting bracket
[For EX-23□ only]
MS-EX20-5
It can adjust the height and the angle of the sensor.
(Two brackets are needed.)
Mounting spacer
For front sensing type
sensor only
MS-EX20-FS
It is used when mounting the front sensing type from the rear side.
(One set consists of 10 pcs.)
Sensor checker
(Note)
CHX-SC2
It is useful for beam alignment of thru-beam type sensors. The optimum
receiver position is given by indicators, as well as an audio signal.
