The Hengstler RI32 incremental rotary encoder is designed to be economical; it is light, versatile and compact with an external body diameter of only 30mm, and due to its small size and the plastic outer casing it is typically used for light-duty applications.

Mounting options are pilot flange only with resolutions up to 1,500 pulses, available with shaft diameter sizes of 5mm and 6mm and shaft protection class ratings of up to IP40.

Cable outlets can be radial or axial; standard cable length is 1.5 metres, it is possible to produce encoders with an additional cable length.

The supply voltage is 5V or 10 to 30V DC; output signals are push-pull only.

Encoders are RoHS compliant, UL approved, and CE marked.
