RPB Linear Potentiometer
- Manufacturer: ELCIS Encoder
- Category: Displacement, Linear Potentiometer, SENSORS, Potentiometric linear sensors, Linear Transducers
The RPB linear potentiometer is an absolute (analog) potentiometric transducer with a stainless steel shaft and guides inside the housing.
It is easy to assemble thanks to its cylindrical body and double connection with integrated ball bearings. It is suitable for applications in mechanics, automation, robotics, and industrial vehicles.
It is manufactured in standard stroke lengths from 50 mm to 900 mm with linearity of ±0.05 % and resistance values of 5 kOhm and 10 kOhm. It features standard IP65 protection and a C193 swivel connector. It is supplied with CE marking and a two (2) year warranty from the date of delivery. Available in guemisa.es.
- Dual connection with built-in ball bearings and cylindrical body.
- Axis of stainless steel with internal guides and useful life of more than 100 × 10⁶ cycles.
- Resistive element of conductive plastic with infinite resolution and exit.
- Standard races of 50 mm to 900 mm with linearity of ±0.05 %.
- Protection IP65 standard and swivel connector C193.
Technical Frequently Asked Questions
What range of strokes and resistive values does the RPB cover?
Standard strokes from 50 mm to 900 mm (other lengths available upon request), with 5 kOhm ±20 % up to 600 mm and 10 kOhm ±20 % for strokes of 750 and 900 mm. In the order code, 05 corresponds to 5 kOhm and 10 to 10 kOhm.
How should the RPB 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.
What protection, maximum speed, and mounting options does it offer?
Standard IP65 protection, maximum operating speed of 5 m/s and fixing with movable metal feet.
