• Track speed of rotating shafts or axles.
• Steel or magnetic targets permanently affixed to the face or O.D. of the collars.
• Wide range of bore styles and target patterns.

Stafford’s line of rotary encoder shaft collars provide targets to let variable reluctance sensors track the speed of rotating shafts or axles.

Manufactured in aluminum, featuring steel or magnetic targets permanently affixed to the face and/or O.D. to let variable reluctance sensors track the speed of rotating shafts or axles.

Designed for new and retrofit applications, standard and custom designs are offered to add rotational speed sensing on shafts from 1/2” to 10” I.D.

Available in one- and two-piece styles, Stafford Rotary Encoder Collars can incorporate a wide range of target patterns. 

To match existing shafts the bores can be round, square, hexagonal or threaded. 

Unaffected by oils and coolants, the collars can be anodized in various colors to match equipment.
