Pankaj potentiometers has been the pioneer in development and manufacturing of wire wound potentiometers in india since 1959. Continuing with our track record of regularly bringing to the market new products developed with our in-house expertise, we now introduce rotary conductive plastic servo potentiometers (model rcp-50).
"Pankaj", keeping in line with the policy of pioneering to manufacture potentiometer with 100% own technology, introduces Short Stroke Potentiometer, Type LCP-20 Housed in 20mm square, strong glass reinforced engineering plastic, flange type mounting with M4 screws. Output connections are through tinned copper TEFLON wires. Major application is foot / hand operated actuators, automotive, switch gears, feedback controls viz.: Displacement, Pressures in hydraulics & pneumatics, variable limit switch, variable brakes sensor etc.
This product is the result of PANKAJ's Policy to develop new products as import substitute. The efforts were acknowledged by winning an award for BEST PRODUCTS DEVELOPED BY AN INDIAN EXHIBITOR at ELECRAMA 2002. The product has wider application in linear motion measurement & controls. Few applications are Press Break, Vaccum Circuit Breakers, Industrial machines & others.

10 bit Absolute Analogue Servo Encoder (A2SE) type NCP-307
Absolute Analogue Servo Encoder (A2SE) is operating on Hall's effect principle. There is no metallic moving wiper contacting to element and hence no wear and tear or sliding electical noise. Shaft is rotating endlessly in double ball bearings giving very smooth movement. It has excellent mechanical response with no hystersis in the output. A2SE is enclosed in anodized aluminium housing with IP-65 protection. It is ideal for harsh environment applications.
A2SE incorporates excellent concept of providing Two simultaneous absolute analog outputs without any extenal device viz: 0-10 VDC, 4-20 mAmp and SSI corresponding to 0-3600. Voltage output can be utilized to monitor the position while at the same time current output can be used to transmit the signal at the remote for control. Various outputs can be factory programmed to suit the different use of angular position. Its 10 bit SSI output (optional) can be directly coupled with micro controller for further use.
A2SE can be used in numerous applications, few of which are: As a Feedback element in Dancer application, Tilt sensor, Angular Displacement Measurement, valve Positioning Controls, Robotics, Mobility services / Aids, Marine Instrumentation, CCTV, Camera Positioning, Medical Scanners, Construction Vehicles, Vending Machines, Industrial Power Tools, Workshop Equipments, Front Panel Rotary Controls, Automotive Applications, Wind Direction monitoring, Replacement of Conventional Servo Potentiometer for long maintenance free life.
