Fax: +44 (0) 1465 714974 Email: [email protected] Website: gentech-international.co.uk DESIGN FEATURES ● High or low level sensing ● Normally open or normally closed operation by float reversal ● Reed switch reliability up to 15 watt rating (UL File E153493) ● ● Polypropylene housing and float VCS SERIES VERTICAL LIQUID LEVEL SENSORS Operational Characteristics Contact Configuration Contact ratings maximum (resistive loads) Internal fit ● 1/8" NPT taper or M8 x 1.25mm thread ● Sealing 'O' ring on VCS-02 and VCS-04 suitable for a wide range of chemicals Minimum withstand across open contacts Initial contact resistance SPST 100 250 1.0 15 800 0.25 Volts DC Volts AC Amps Watts Volts Ohms The above contact ratings are for resistive loads. For inductive, capacitive and tungsten filament lamp loads refer to the circuit protection notebook. When the non magnet end of the float is positioned against the float stop (as shown in the drawings over) the switch contacts are closed. The switch function can be changed from contacts normally closed to contacts normally open by simply compressing the float stop arms, removing and reversing the float and reassembling. ● Temperature range up to 70°C ● 30mm or 22mm diameter float options Environmental Specifications ● Minimum SG 0.70 HOUSING AND FLOAT MATERIAL ● Overall length less than 60mm (21/2 inches) ● Interface control system available ● VCS-01 and VCS-02 foamed polypropylene float-magnet wetted ● VCS-03 & VC5-04 hollow polypropylene float-magnet (sealed) Polypropylene NITRILE ‘O’ RING OPERATING TEMPERATURE -30° to +70°C Detailed chemical resistance information for speciflc liquids is available on request.
