Tilt Switch Probe - Model SL20

Supplier: Saimo Technology

When material rises to tilt the probe 15°or more from its vertical position, the internal steel ball rolls off center and its normally closed contacts will open.

Price Guide: POA

As material falls away from the probe body and the probe becomes upright, the ball returns to its original centered position, once again causing switch actuation with the contact closed.

The change in the internal switch status is user accessible for signaling alarms or lights with the aim of safety protection.
