The slit mask is only available for the thru-beam type sensor.
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.
Mounting method
The tightening torque should be 0.5N·m or less.
1
Slip the slit mask onto the sensor.
2
Align the holes and mount with the M3
screws provided.
The optional mounting spacer is only available for front sensing type
sensors.
Part no.
: MS-EX20-FS.
Mounting method
