A standard line of rotary encoder collars providing sensing capability from their O.D. or face is now available from Stafford Manufacturing. According to the company’s press release, the collars mount directly onto any shaft and feature corner-mounted steel targets. Made of anodized aluminum, these two-split designs come in 11 standard sizes and are unaffected by oils and coolants.

Applications for the rotary encoder collars include electromagnetic sensor mounting assemblies that are compatible with all popular sensors. Special bore configurations, target locations and custom sizes for shafts up to 10" O.D. are also offered. Collars are priced to size and quantity; literature is available upon request.
