MEDER electronic LS02 Series Level Sensors with Magnetic Floats DESCRIPTION Standard liquid level sensor. The sensor has to be mounted vertically for best results. APPLICATIONS Two versions are available: PP (Polypropylene) for water applications and dilute acids PA (Polyamide) for use in oil, gasoline (petrol) and brake fluid * 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 * IP 68 (only to screw thread) MATERIALS Materials PA version Shaft, nut Polyamide black Float Polyamide black S eal Nitrile rubber Materials PP version Shaft, nut Polypropylene black Float Polypropylene black S eal Nitrile rubber www.meder.com Germany # ++49-(0)7733-94870, USA # 800-870-5385 231 LS02 Series MEDER electronic Level Sensors with Magnetic Floats MOVEMENT ORDER INFORMATION SERIES CONTACT FORM SWITCH MODEL MATERIAL CABLE LENGTH (mm) TERMINATION LS 02 - XX XX - XX - XXX X LS02 - 1A66 - PA - 500 1 Form A OPTIONS 66, 84 PA, PP 500 * Part Number Example W, X, Y 1 Form B * Other cable lengths available. 1A is the contact form 66 is the switch model PA is the material 500 is the cable length (mm) W is the termination TERMINATION For wire and termination details please consult factory. www.meder.com 232 Germany # ++49-(0)7733-94870, USA # 800-870-5385 W MEDER electronic LS02 Series Level Sensors with Magnetic Floats CONTACT DATA Switch Model --> Contact For m --> All data 20 0C Contact Ratings Conditions Switch 66 For m A / B Min.
