Turn a shaft encoder into a linear measurement solution

Programmable encoder for versatility

If you need to program the specifications in your encoders, the programmable Model 25SP Accu-CoderPro® is your answer. There are 6 output options, 32 waveforms to choose from, and you can choose any resolution from 1 to 65,536 CPR – that's 262,144 counts using 4x quadrature counting.

This shaft encoder is designed for the challenges of an industrial environment and offers a variety of shaft sizes, a range of connectors, and sealing up to IP67. The Model 25SP Accu-CoderPro® comes standard with dual bearings rated 80 lbs axial or radial, and offers up to IP67 sealing. Some configurations are in stock and ready to ship. And we've made it easy for you to configure: you can simply order a kit for your Programmable Linear Measurement Solution.

Additional bearing load with an industrial housing

For applications requiring additional bearing load, the Model 725I Accu-Coder® features an extra-heavy-duty industrial housing. In addition to the rated bearing load of 80 lbs, the fully isolated encoder-within-an-encoder design provides an additional layer of protection by using an internal flexible mount and independent set of bearings, which further protect the encoder from the effects of severe axial and radial shaft loading.

Multi-turn absolute feedback

Our new bracket is specifically designed to fit our Size 25 shaft encoders, and that includes our absolute Model A25SB. The Model A25SB multi-turn absolute encoder is ideal for a wide variety of industrial applications that require an encoder with the capability of absolute positioning output, even in power-off scenarios. Offering either SSI or CANopen® communication protocols, the Model A25SB features absolute feedback with resolution up to 16 bits single turn and 43 bits multi-turn. Its fully digital output and innovative use of battery-free, multi-turn technology make the Model A25SB exceptionally reliable. The Model A25SB's robust and durable magnetic technology and available IP67 seal readily handle the harshest industrial environments, including those with elevated electrical noise.

Two Options for Your Bracket

Both types of bracket allow for convenient mounting of an encoder and measuring wheel over the surface being measured, and both allow the assembly to adjust pitch for variations in material height.

• The Single Pivot Bracket is gravity loaded and uses the combined weight of the encoder, measuring wheel, and bracket to provide surface torsion.
• The Spring Loaded Single Pivot Bracket uses a spring-loaded bracket, which provides an adjustable surface torsion. This allows the encoder and measuring wheel to be mounted in almost any orientation, even upside down.

Measuring Wheels

Encoder Products Company offers measuring wheels in four different contact surfaces, all made of high grade aluminum alloy. For more information on choosing the right measuring wheel for your application, refer to Technical Bulletin TB-108 Encoders with Measuring Wheels.

Rubber Insert

Rubber insert wheels have less surface area in contact with the material, so more pressure is applied, resulting in less slippage. Rubber insert wheels are good for materials such as (but not limited to): paper, film, foil, hard plastic, and other smooth materials.

Polyurethane

This smooth, versatile material comes in different durometer ratings (that is, degrees of hardness). Polyurethane is good for materials such as (but not limited to): metal pipe, sandpaper, matting, cardboard/packaging, belting, insulated wire, metal, etc.

Knurled Aluminum

Knurled aluminum offers good traction, but should not be used with delicate materials. It is a good choice for materials such as (but not limited to): metal pipe, sandpaper, matting, cardboard/packaging, belting, insulated wire, metal, coarse fabric, cloth tape, rubber, rough wood, carpet, foam, insulation, or other rugged materials that won’t damage easily from constant contact with the wheel.

Hard Anodized Knurled Aluminum

Anodizing hardens the aluminum and prevents corrosion, so these wheels are good for harsh environments where there may be washdown or exposure to corrosive elements. These wheels are also not meant for delicate materials, and are excellent for materials such as (but not limited to): coarse fabric, wood (i.e., lumber cut-to-length), or other durable materials.
