Product Description:

The HS35R20488577 Sealed Hollowshaft Encoder delivers consistent and reliable operation across a broad range of industrial applications involving varying speeds, temperatures and signal requirements.

This HS35R20488577 sealed hollowshaft encoder exhibits a minimum frequency response of 100 kHz. This corresponds to its ability to accurately process input signal changes up to 100,000 cycles per second. This threshold ensures reliable output signal integrity at high rotational speeds. This model supports applications where pulse rates and edge transitions occur at high frequencies without loss or distortion. It operates reliably across a wide range of ambient conditions with a standard operating temperature range of - 40 °C to + 70 °C. For high temperature applications, it supports an extended operating range up to +100 °C. Thermal management components and internal circuitry of this encoder are designed to maintain performance stability and prevent thermal drift or degradation across the specified temperature span. To prevent overheating during high rotational speeds, temperature derating is applied: for shaft bores of 5/8 inch or smaller, derate 5 °C per 1000 RPM above 1800 RPM; for bores larger than 5/8 inch, derate 10 °C per 1000 RPM beyond the same threshold.

This model is capable of withstanding extreme environmental stress with a storage temperature rating from - 40 to + 90 °C. Its electrical output flexibility allows integration with different drive systems and control interfaces. The open collector output of this encoder is designed to handle higher voltage levels while the push pull and differential drivers offer improved noise immunity and signal integrity across longer cable distances. High current capability from the 4469 driver supports robust signal transmission. Wake Industrial has this Danaher Encoder in stock and offers one year replacement warranty as well.
