Madison Company's M4189 tilt float switch is an inexpensive, efficient and highly reliable level detector for open vessels, sumps and ponds. Standard cable length is 6.5' (2 meters) of PVC Jacket. The molded rubber float has an integral three conductor cable and operates on a micro-switch device that is located inside the float on an anti vibration mount. The rubber float is constructed of ethylene propylene diene (EPDM), a synthetic rubber with rigid and durable characteristics for long service life and resistance to heat, oxidation, ozone and aging due to weather. As a non-polar elastomer, EPDM has good electrical resistivity, as well as resistance to polar solvents such as water, acids, alkalies, phosphate esters and many ketones and alcohols. The basic operating principle is that as the fluid level rises the float will rise, causing the micro switch to tilt and generate a signal that can be used to start or stop a pump, open or close a valve or actuate indicator alarms as required. Float travel is approximately +/-45 degree are from its nominal position. Low cost, easy installation, versatile in application. Stem and float SG 2.16 g/cubic cm. 65 ft Maximum submerged depth. Directly 1 KW with 250 V circuit breaking capacity. Polypropylene sealed housing. Contact rating: 16 (8) A 250V ~ 16(4)A 380V.
