HB6M Product Description
The HB6M is a high-resolution hollow bore (hollow shaft/thru-bore) optical encoder with a machined aluminum enclosure and an anodized protective finish. The HB6M optical incremental encoder is designed to easily mount to an existing shaft to provide digital feedback information. Typical applications include motor feedback, process control, robotics, textile machines, and elevator controls.
The HB6M bearing style encoder features a hollow bore that accepts shaft diameters from 0.236 in. to 0.750 in. in diameter. The encoder slips over the shaft and is locked into place with two 6-32 set screws. A flexible anti-rotation mount makes the encoder more tolerant of shaft runout than a standard kit encoder. The HB5M can accommodate shaft axial play up to ±0.030 in. and shaft runout up to 0.010 in. The flexible tether provides single-point mounting for bolt circle diameters from 2.5 in. to 5.0 in.
The HB6M housing comes standard with a closed cover or an optional hole in the body to allow a shaft to pass completely through the encoder.
A secure connection to the HB6M Series encoder is made through a 5-pin (single-ended versions) or 10-pin (differential, high-voltage or open-collector versions) latching connector. The mating connectors are available from US Digital with several cable options and lengths.
