4.5.2 Installation of RF
Mounting of sensor electronics housing requires the use of
2 non-magnetizable screws M4×59.
NOTICE
A flexible sensor requires supports or anchoring to maintain proper
alignment between sensor rod and the magnet, otherwise the
sensor output signal can be interfered or lost.
Curvilinear measurements
Long sensors require a support tube (inner diameter of 9.4 mm
(0.37 in.)) of non-magnetizable material, straight or bent to the desired
For easy installation the sensor is supplied with a hex 46 flange (ac-
cessory) bored for above mounting screws.
