Hengstler RI41-O incremental rotary encoders offer exceptional performance in industrial applications where reliability and high pulse frequencies are necessary and competitive pricing is a priority.

Hengstler RI41 incremental encoders are 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 of 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; the standard cable length is 1.5 metres, producing the RI41 encoder with additional cable lengths is possible.

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

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