RPC Linear Potentiometer
- Manufacturer: ELCIS Encoder
- Category: Displacement, Linear Potentiometer, SENSORS, Potentiometric linear sensors, Linear Transducers
The RPC linear potentiometer is an absolute (analog) potentiometric transducer with a stainless steel shaft and guides inside the housing.
The manufacturer's English data sheet indicates applications in hydraulic and pneumatic cylinders, plastic molding, packaging, textile machinery, etc.; the Italian data sheet lists plastic molding and woodworking machinery, etc. Please confirm with Guemisa before ordering. Electrical connection is made via a DIN 43650 IP65 – ISO 4400 swivel connector.
It is manufactured in standard strokes from 50 mm to 900 mm with linearity of ±0.05 %, infinite resolution, resistance values of 5 kOhm and 10 kOhm, and options for ball joint head (option 1), axial ball joint (option 2), or IP65 sealing (option 3). Available in guemisa.es.
- Adjustable connector DIN 43650 IP65 – ISO 4400.
- Maximum operating speed of 10 m/s and a lifespan exceeding 100 × 10⁶ cycles.
- Element of conductive plastic with infinite resolution and linearity of ±0.05 %.
- Standard races of 50 mm to 900 mm with resistors of 5 kOhm and 10 kOhm.
- Options patellar head, axial joint and IP65 sealed.
Technical Frequently Asked Questions
What type of connector does the RPC linear potentiometer use?
The electrical connection is made using an adjustable connector according to DIN 43650 IP65 – ISO 4400.
What axle mounting options are available?
Ball joint head (option 1) or axial ball joint (option 2); option 3 is the IP65 sealed version.
How should the RPC be used in the measurement circuit?
It should be used as a voltage divider with a maximum current of 1 µA at the cursor contact; if the connected system requires more current, an additional circuit will be necessary.
