Rotary Encoder Collars
Stafford Manufacturing Corp. offers a full line of rotary encoder collars that can be mounted on any rotating shaft or axle to measure speed and provide direct feedback. Stafford Rotary Encoder Collars are aluminum one- and two-piece designs that can be mounted directly onto a shaft or axle and feature permanently affixed steel targets that are accessible from the face or O.D. Unaffected by oils and coolants, these encoder collars are ideal for new and retrofit applications and allow speed sensing using a variable reluctance sensor. Available in 11 standard sizes from ½-inch to 3-inch I.D. with 2-inch to 5-1/2-inch O.D., and target spacing depending upon size, Stafford Rotary Encoder Collars can also be supplied in custom sizes. Special finishes and bore sizes up to 10-inch I.D. and O.D. sizes with targets to match specific customer requirements are offered.
