R35iL rotary encoders

As a particularly low-profile and low-weight alternative to the R35i, RENCO also offers the R35iL rotary encoder. It can be used in the same types of applications but, thanks to its low height of just 8.6 mm, lends itself particularly to applications with critical installation parameters and limited space.

Even with its low footprint, the RENCO R35iL still offers state-of-the-art performance capabilities. These include a resolution of up to 5000 signals per revolution, commutation signals (U, V, and W), and an operating temperature range of –30 °C to +115 °C.

With its integrated mounting aid, the R35iL is also equipped for convenient, self-centering installation. The R35iL runs on a supply voltage of either 3.3 V or 5 V.
