mounted vertically for best results.
Two versions are available:
PP (Polypropylene) for water applications and
dilute acids
PA (Polyamide) for use in oil, gasoline (petrol) and
brake fluid
APPLICATIONS
• Liquid container monitoring in household
appliances, automotive applications, test and
measurement, and control technology.
The standard termination is a PVC cable with a
cross section of 0.14 mm2 and a length of 500 mm.
The cable can be modified on request.
DIMENSIONS
All dimensions in mm [inches]
FEATURES
• High power switches available
• Other cables, connectors and colors available
• Form A (normally open) and Form B (normally
closed) types are available
