User Manual

2
When mounting the sensor with the optional mounting bracket, use the
attached M2 screws. The tightening torque should be 0.2N·m or less.
Six types of optional sensor mounting brackets are available.
Optional slit masks help the sensor detect small objects. The accuracy of
the position being sensed is also increased. However, the sensing range is
reduced.
 Attach the slit mask to the sensor before mounting the sensor.
If both the slit mask and the mounting bracket MS-EX10-1 or MS-EX10-11
are attached to the front sensing type sensor, use a spacer that is at least
0.2mm thick, as shown in the figure.
The following symbols are used in this section.
NPN output type
 Only the thru-beam receiver incorporates the output.
PNP output type
 Only the thru-beam receiver incorporates the output.
