Avtron HS25A Encoders easily fit shafts from 3/8" to 3/4", using a durable shaft insert. Units may be resized by replacing or removing the insert, enabling our factory, distributors, and customer stockrooms to swiftly meet any need. The shaft insert (3/8" to 5/8") also provides isolation from motor shaft currents, while permitting case grounding to meet NEC requirements.

Stork Veco manufactures custom designed encoder discs, masks and strips for motion control applications ranging from the commonplace to the specialized. These unbreakable metal components are ideal for meeting rugged motion control requirements and the electroforming manufacturing process assures excellent product quality. Electroformed encoder discs/strips/masks are characterized by very uniform aperture sizes with sharp straight edges.

Our technical flexibility allows us to produce a wide range of designs. The maximum disc diameter is 6" (150 mm) and the maximum strip length is 39" (1 meter). The +/- 0.0004" (0.010 mm) tolerance assures excellent window to window repeatability and tight center hole concentricity which eliminates the extra assembly work required with other types of materials. With a minimum pitch of 0.0026" (0.065 mm), pulse counts up to 1024 PPR can be achieved in a disc size of approximately one inch and much higher for larger sized discs.

Stork Veco has the ability to produce parts in different batch sizes which allows for competitive pricing for both small and large production runs. Most of the film tooling work is done in house to keep start up costs low. All we need is a mechanical drawing of the part you require and an estimate of the annual volume and we can provide a price quotation.

HS35A encoders fit shafts from 1/2"to 1" easily, using a durable shaft insert.Models from 1/2" to 7/8" [12mm to 20mm] may be resized by replacing the insert, enabling our factory, distributors, and customer stockrooms to swiftly meet any need.The shaft insert also provides isolation from motor shaft currents, while permitting case grounding to meet NEC requirements. Avtron encoders have superior shaft seals and bearings that stay sealed to keep out contamination caused by temperature cycling and liquid sprays. Our encoder seals are protected by mechanical barriers to prevent flexing or failure, and Avtron's superior bearings feature synthetic lubricants for even longer life. Many competitive optical encoder designs risk sensor damage from any vibration or shock: sensors ride less than four thousandths of an inch from the thin, often flexible, optical disk spinning at full motor speeds. Some designs even use thin glass disks in "industrial" products! Avtron uses only unbreakable disks and a sensor to disk gap over 8X larger than the competition. Our optical HS35A encoders use superior sensor, disk, bearing, and seal technology to give top performance in industrial conditions. In many cases you cna replace competative models without rewiring. The encoder fits on end of shaft and through shaft applications. It can be supplied with a rugged protective basket. IP65/Nema 4, 13 Rating: Dust and Liquid Tight, -20°C to +100°C Operation allow us to offer it with a 2 Year No-Hassle Warrenty.

The heavy duty rail proven NorthStar HSD44 optical encoder is a anodized aluminum encoder that can survive high levels of shock and vibration, wide temperature extremes and operating environment contaminants.

The 1024 pulses per revolution are provided by a rugged stainless steel disc which is read from a specially designed optical sensor. An enormous .025" sensor gap reduces sensitivity to shock vibration and motor bearing wear. The counter spiral shaft-coupler provides a flexible mount that eliminates resonance throughout the operating range and will not fatigue under vibration. Electronics are condensed down to a single ASIC, reducing the likelihood of electronic component failure.

The NorthStar HSD44 is designed for end-of-motor application. Adapter plates are available for common motor styles and custom adapter plates can be created to fit any application.
