Rotary Encoder Collar can be used to sense shaft speeds.

Press Release Summary:



Aluminum clamp-type collars can be configured with metallic targets to permit shaft speed sensing. Metallic targets can be read by customer-supplier variable reluctance sensors. Collars are unaffected by oils and coolants, and smooth bore will not damage shafts. They are available in one- and two-piece clamp-type designs with bore sizes from 1/2 in. and ODs up to 12 in. Applications include positive feedback in closed-loop systems.

Rotary Encoder Collars Solve Rotational Measurement Problems


A lightweight series of aluminum clamp-type collars that can be custom configured with metallic targets to permit shaft speed sensing is available from Stafford Manufacturing Corp. of Wilmington, Massachusetts.

Stafford Rotary Encoder Collars are made from aluminum and feature metallic targets which can be read by variable reluctance sensors (customer supplied) aimed at them. Allowing shaft speed sensing to solve rotational measurement problems, these encoder collars can be custom fabricated with user-defined target positioning and are unaffected by oils and coolants.

Suitable for new and retrofit installation, Stafford Rotary Encoder Collars can be supplied in one- and two-piece clamp-type designs in bore sizes from 1/2" and O.D.s up to 12" with target spacing to specification on the face or O.D. Applications include shaft synchronization and positive feedback in closed-loop systems. These smooth bore collars will not damage shafts.

Stafford Rotary Encoder Collars are custom fabricated and priced according to configuration and quantity.
