Hengstler hollow hub shaft incremental rotary encoders have body sizes between 36mm and 63mm diameter. Unlike through shaft encoders the rotating shaft is completely enclosed within the casing therefore the shaft will be restricted to a maximum length. The housing of the encoder is secured via a spring tether or stator coupling and the rotating shaft is secured in most examples by means of a clamping ring and set-screw. Typical hub shaft sizes are between 4mm and 16mm with protection class ratings of up to IP67 and resolutions of up to 10,000 PPR (Pulses Per Revolution). Output signals include 10-30V DC push-pull, push-pull complimentary or 5V DC RS422 with a sense or an alarm output option. See the individual data sheets for exact product specifications. Solid shaft rotary encoders are RoHS compliant, UL approved and CE marked. Typical applications include; actuators, motors and general industrial use.
