Product Description:

The HS35R00607305 is a hollow-shaft incremental encoder manufactured by Danaher for the Dynapar Encoders series. It mounts on the end of a motor or fan shaft and translates mechanical rotation into electrical pulses. Drives or PLCs can count these pulses for speed or position regulation in automated equipment.

This model delivers a resolution of 60 PPR, meaning one full revolution produces sixty evenly spaced pulses that a controller can use for coarse velocity tracking or commutation. A minimum frequency response of 100 kHz keeps those pulses accurate even when the application demands rapid acceleration. The internal bearings permit a maximum shaft speed of 3600 rpm, and they are rated for 80,000 h at 3600 rpm to support long maintenance cycles. An enclosure rating of NEMA 4/IP66 protects the electronics from dust ingress and high-pressure water spray during washdown. The encoder uses an open-collector output, so it sinks current to ground and can be wired directly to common sourcing inputs. The device emits a single-ended, unidirectional A channel, and it draws no more than 5.0 oz-in of starting torque, reducing the load on small drive systems. A moment of inertia of 7.9 × 10⁻⁴ oz-in-s² allows quick speed changes without introducing lag. The overall diameter is 3.54 in, and the slotted fan-cover mount allows the housing to be rotated for cable alignment after clamping. The electrical connection uses a 6-pin plug, and the mating connector half is supplied.

The mechanical interface supports an axial load of 30 lb and a radial load of 40 lb, protecting the bearing set when belts, couplings, or overhung fans pull on the shaft. A 1/2 in bore passes completely through the unit, allowing the encoder to slide over a standard motor shaft. The encoder locks in place with a split collar, so no additional stub shaft is required.
