The Hengstler RI41 incremental rotary encoder offers high performance at an economical price for use in industrial applications where reliability and high pulse frequencies are required.

The Hengstler RI41 incremental encoder is economical; the 40mm diameter aluminium housing ensures it is light yet robust, equally suited to industrial or light duty applications.

Mounting options are pilot flange with resolutions up to 3,600 pulses, available with a shaft diameter size of 6mm and shaft protection class ratings of up to IP40.

Cable outlets are radial only; standard cable length is 1.5 metres, it is possible to produce the RI41 encoder with additional cable lengths.

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

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