  • Potentiometer V.R-1CT is a panel setting device for a maximum wattage ratting upto 3 watt with Center tape.
  • V.R.-1CTis also known as 4 wire potentiometer
  • V.R-1S is mainly used for economical solution with low life cycle, 5% Linearity tolerance and high current consumption applications. This is a ideal product where we need to operate a relay directly from the sensor without use of any more electronics.
  • 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 30k ohms, with center tape provision to have differential output.
  • The capability of the company to produce a vast range of potentiometer is a USPon its own.
  • The Product can be made to Ingress protection upto IP65 on request.
  • V.R-1CT has several other variants with model number V.R-1G (GangedPotentiometer), V.R-1S (Endless Potentiometer), PM111 (panel setpotentiometer).

Mounting Specification / Acessories

For best performance of V.R-1CT below points needs to be taken into consideration.
1) The hole in the panel should not be more than 9.5mm.
2) V.R-1CT should be mounted with Star washer given along with the product and perpendicularity between the panel and axis of potentiometer should be maintained.
