Dynapar. Innovation, Customization, Delivery.

Dynapar makes the broadest line of trusted brands in motion feedback control, including Dynapar and Hengstler brand incremental encoders and absolute rotary encoders, heavy-duty Northstar encoders and high-performance Harowe brand resolvers.

Dynapar offers the world’s broadest range of reputable brand name encoder products to satisfy a full range of industrial factory, motor speed, cut-to-length and positioning applications. A recognized leader in absolute rotary encoders, commercial light-duty, industrial incremental and motor mount feedback controls, Dynapar has supplied encoder system solutions to customers the world over for over 50 years - effectively establishing themselves as a recognized leader in motion feedback controls.

Absolute Rotary Encoders

Keep track of position at all times and provide a cost-effective solution in many motion control and industrial automation applications. Acuro Series rotary encoders solve the age old problem of establishing a home position without causing costly downtime or scrap. They always know their position whereby factors such as inactivity for long periods of time and/or moves at a slow rate have no effect on these encoders.

General-Purpose Incremental Rotary Encoders

Deliver precise digital feedback for fractional horsepower motors in relatively clean environments. Dynapar Incremental Rotary Encoderswith integral shaft size from 1/8” to ˝” and housing size ranges from 1 to 2.5 diameter include electrical interface via side or end mounted MS connectors with choice of flange, servo of face mounting configuration options.

Flexible Shaft Couplings

Excessive shaft loading and poor environmental isolation are the leading causes of encoder failure and operational errors.

Even the most carefully designed machinery will produce shaft forces due to inherent thrusts, and eccentricities. Since encoder shafts and bearings must be engineered to have very restricted axial and radial play, using a Dynapar brand CPL Series coupling affords maximum protection against these common hazards.

CPL Series couplings are carefully matched to the requirements of our encoders and are an excellent, low cost way to protect your investment and avoid equipment downtime.

A unique 3-beam design divides the coupling's helix into three segments.

This feature maintains transfer accuracy by restricting windup during torque, yet retains full protective flexibility.

In addition to controlling mechanical shaft and bearing loads, the coupling further protects the encoder by providing a high degree of electrical and thermal isolation between coupled shafts. This is accomplished with a phenolic insulator-insert that blocks passage of potentially damaging heat, electrical currents and static charges.

Each CPL Series coupling is supplied with two insulator-inserts (three for metric models) that allow it to fit standard shaft diameters (see Models table, Secondary Bore).

Attachment at both ends is via integral 360° clamps that firmly grip the encoder shaft and input shaft, remaining slip-free to the rated torque of the coupling.
