Using a different actuating element
The BT-F130-A actuator included can be replaced with a different actuator, provided that the
new actuator fits in the sensor opening. When using a different actuator element, the element
must fulfill all requirements relating to the material, dimensions and distance to the sensitive
surface on the sensor (see table). Failing to fulfill all of these requirements may reduce the
accuracy/resolution of the sensor or even prevent it from functioning.
The actuator (C) can be placed on the insulating ring made from non-conductive mate
-
rial (B) or inserted in this ring.
