PLMS | Programmable Linear Measurement Solution

  • Programmable Incremental Feedback
  • Absolute Feedback

PLMS Description

The BEPC Programmable Linear Measurement Solution allows for the selection of the encoder type (absolute or programmable incremental), output type or protocol, measuring wheel type and size, optional mounting bracket, and optional programming kit (for the programmable incremental encoder). This wide array of component choices permit a flexible, robust measurement solution that can be fine tuned to meet the exact requirements of your application.


PLMS Step 1: Start with your spring loaded mounting bracket

Spring loaded mounting bracket

Stock #176742-02

This spring loaded mounting bracket fits 2.5” (63.5mm) shafted encoders with servo mounts, and 58 mm shafted encoders with clamping flanges. It allows convenient application of an encoder and measuring wheel solution directly to a surface being measured. The bracket features a torsion spring, adjustable to up to 10 lbs of force, which permits the encoder and measuring wheel to be mounted in almost any orientation, even upside down. The single pivot action allows the assembly to adjust travel and wheel pressure for variations in material height. All units in inches and mm unless otherwise noted.

*The MG flange is also an option, but it will limit the orientation of the encoder to 120° increments

PLMS Step 3: Select your measuring wheel

Measuring Wheels

British Encoder Products Company offers to measure 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 our Measuring Wheels Datasheet and also our Technical Bulletin TB-108 Encoders with Measuring Wheels. Please specify 3/8" as the bore size to match encoder above.

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.


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 a 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.

PLMS Step 4: Consider your accessories

Angled Mounting Bracket

Stock #176389-01


This bracket simplifies installation of your linear measurement solution. Designed specifically for BEPC products, this bracket allows you to mount and install your encoder, bracket, and measuring wheel quickly and easily, without having to design, machine, or source a mounting solution .

USB Programming Kit

Stock #PR1-001 + Connector Cable


The USB Programming Kit is required for field programming capability for the Model 25SP, and is available with any connector. See below for the User Guide, Quick Start Instructions, the video to see how simple it is to program your Model 25SP.
