Direct Adhesive Mount Procedure
Direct Adhesive Mount Procedure
For restrictions of space or for convenience, most sensors (with the exception of integral stud models) can be
adhesive-mounted directly to the machine surface.
STEP 1 Prepare a smooth, flat mounting surface. A minimum surface finish of 63 µin [0,00016 mm] generally
works best.
STEP 2 Place a small portion of adhesive on the underside of the sensor. Firmly press down on the top of the
assembly to displace any adhesive. Be aware that excessive amounts of adhesive can make sensor removal
difficult.
