  • Potentiometer V.R-3 is a panel setting device for a maximum wattage ratting upto 3 watt.
  • V.R-3 has been specifically designed to have longer life, No discontinuity and smooth movement of shaft.
  • It has a feasibility to customize in several ways. Such as shaft modification, lug terminal arrangement, a vast range of ohmic value from 10 ohms to 100k ohms.
  • The capability of the company to produce a vast range of potentiometer is a USP on its own.
  • The Product can be made to Ingress protection upto IP65 and above on request.
  • V.R-3 has several other variants with model number V.R-3G (Ganged Potentiometer), V.R-3S (Endless Potentiometer), V.R-3CT (4 wire potentiometer), V.R-3SW (Potentiometer with switch)


For best performance of V.R-3 below points needs to be taken into consideration.
1) The hole in the panel should not be more than 9.5mm.
2) V.R-3 should be mounted with Star washer given along with the product and perpendicularity between the panel and axis of potentiometer should be maintained.
3). For applications with extreme vibration please use lock nut assembly which is being supplied on the demand.
