Mounting to exclude the application of force on the housing, the active surface of the head or cable. The sensors should be fastened using the nuts supplied.
Attention! In the sensor head area, the allowable torque for tightening the nuts is reduced by half! Permissible tightening torque for plastic housings – 1.5Nm.
