Material: Stainless
Note: 1. The protective height of the F3SJ-E/B series that supports the contact mount bracket is limited.
Protective height allowed for mounting: 185 mm to 1,105 mm (225 mm to 545 mm for the model with the
suffix "-02TS")
2. Brackets of other models such as F39-LJB1 cannot be used simultaneously.

* Use F = 350 or less when none of the F values shown above are used.
When only F39-LJ3 free-location mounting brackets are used without standard brackets, allow a space of at least 350 mm between the brackets. The number of brackets required varies according to the protective height. For details about the number of required brackets, refer to the table below.
The standard included intermediate brackets are the same as the F39-LJ3 free-location mounting brackets. Purchase brackets as necessary if there are fewer intermediate brackets than required. When intermediate brackets are included, they can be used as free-location mounting brackets.

F3SJ-A to F3SJ-E/B replacement correspondence table (F3SJ-A mounting holes can be used without modification)
To check available brackets for replacement, refer to the table below.
To check dimensions when mounting brackets, refer to Catalog.
The values in the table correspond to in the model name, meaning the protective height (mm) of a sensor.
Note: 1. Protective height and detection capability vary according to replacement. Check the safe design of your device
before use.
2. The maximum protective height of F3SJ-E is 1,105 mm. Only the F3SJ-B can be replaced for the protective

Change of Dimensions due to Replacement
(1) Replacement by backside mounting
Dimensional drawing from mounting wall surface to optical surface
(2) Replacement by side mounting
Dimensional drawing of a protrusion from mounting wall
Replacement using intermediate brackets
For backside mounting, the F3SJ-A and F3SJ-E/B can be used without modification due to compatibility in mounting hole pitch. For side mounting, a new hole needs to be made due to the different mounting hole pitch.
