LS02 Series MEDER electronic Level Sensors with Magnetic Floats DESCRIPTION Standard liquid level sensor. The sensor has to be 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 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. APPLICATIONS • Liquid container monitoring in household appliances, automotive applications, test and measurement, and control technology. FEATURES • High power switches available • Other cables, connectors and colors available • Form A (normally open) and Form B (normally closed) types are available • IP 68 (only to screw thread) ORDER INFORMATION Part Number Example Series Contact Form Switch Model Material Cable Length (mm) Termination LS02 - XX XX - XX - XXX X 66, 85 PA, PP 500 * W Options 1 Form A 1 Form B * Other cable lengths available.
