RH 200 

The RH 200 metric wheels are designed for specific industrial applications where is required to measure a linear movement (i.e. continuous sheet cutting machines of wood, textiles, glass, etc.). Precise reading and high-stress resistance are the main features of these encoders. The body is entirely designed of aluminium and mounted using an oscillating arm pivoted on the shaft. It comes with an integrated self-lubricating compact box to assure a long operation period without any maintenance. The weight of the metric wheel keeps a stable contact with the material, allowing an accurate measurement of both length and speed. The wheel surface can be in crossed-knurl aluminium, special anti-oil or anti-sliding rubber.

EP rotary encoders series with potentiometric output signal. The potentiometer is fitted in a sturdy housing and it's supported by two bearings, assuring excellent lifetime, speed and accuracy.

Rotary encoders are electro-mechanical devices used to monitor and control the position and angular speed of rotating shafts. In particular, incremental encoders track positional changes relative to a defined reference point. As a result, they operate independently of the direction of rotation. By generating electrical pulses, they measure rotation, speed, and acceleration. However, the reference (zero) position must be reset at each system start-up.

Rotary encoders are electro-mechanical devices designed to control the position and the angular speed of mechanical axles in motion. Rotary incremental encoders are so defined since they track the increase (variation) in respect to a position taken as a reference point and independently from the direction of the rotation.
