ENCODER PRODUCTS COMPANY
ABOUT ENCODER PRODUCTS COMPANY
Encoder Products Company (EPC) is a global motion sensing device creator. EPC started out as a modest, home-based firm in 1969, creating a line of custom encoders (the original Cube series). EPC is now one of North America's largest privately held encoder producers, with the industry's most comprehensive portfolio of incremental and absolute rotary encoders.

PRODUCT HIGHLIGHT
TRP TRU-TRACPRO™
ALL-IN-ONE PROGRAMMABLE WHEELED ENCODER WITH MEASURING WHEEL & SPRING-LOADED TORSION ARM
As an upgrade to the TR1 Tru-Trac®, the TRP Tru-TracPro™ is a programmable incremental encoder that offers versatile options for tracking velocity, position, and distance over many surfaces at speeds of 3,000 feet per minute. These encoders can be easily programmed and re-programmed to fit any system's requirements, given you maximum flexibility and control. When used with the PR2 Programmer, users also gain access to many other features.
The TRP Tru-TracPro™ has a durable construction that allows it to be used in the most harsh industrial environments. It’s ideal for everything from automation to packaging, printing, vision systems, material handling, and more. Since it has an identical form factor to the TR1 Tru-Trac®, it can be easily dropped into an existing automation system.

TRP TRU-TracPro™ Features
- Resolutions from 1-100,000 CPR
- Operates over a variety of surfaces at speeds up to 3,000 feet per minute
- Choose from 40 options with a customizable waveform output
- Fast implementation and activation with PR2 programmer and free software download
- Can be installed in a vertical, horizontal or upside-down orientation
- Choose your exact CPR without changing wheel sizes
- Can be field calibrated for high performance and accuracy
- Fast installation for mounting on any surface
- Teach index location
- Simplified design allows for reduced cost and inventory
- Gear option is available when used with an optional rack
- Easy wheel pressure adjustments with spring loaded torsion arm
- Restore factory settings and reprogram as needed to match your system’s requirements
MODEL A36R ABSOLUTE ENCODER
Multi-turn thru-bore or blind hollow bore encoder | 36 mm (1.42") | BiSS C or SSI communications
The Model A36RTB (thru-bore) or A36RHB (blind hollow bore) offers a high-performance solution to your absolute feedback needs. Its innovative blue LED and reflective sensor technology deliver accurate high-resolution feedback in a compact thru-bore housing. The XXL multi-turn option adds a low power turns-counting circuit offering a variety of backup options including EPC’s embedded battery cable, which has a long-life battery built directly into the controller-end of the cable.
This encoder is especially suited for applications where position information must be retained after loss of system power. The use of blue LED and reflective technology along with excellent shock and vibration ratings make it a highly versatile encoder. Available with bore sizes up to 10 mm and a wide selection of flexible mounting options, the Model A36R is easily designed into a variety of applications.
Model A36R Features
- Single turn/multi-turn absolute encoder (22 Bit ST / 24 Bit MT)
- BiSS C or SSI communication
- Standard 36 mm dia. package (1.42")
- Low profile – 1.0" (25.4 mm) depth
- Flex mount options eliminate couplings and are ideal for motors
- Optional battery/backup power interface for data retention in the absence of primary power
- Available with bore sizes up to 10 mm
BiSS C Encoder Interface
The A36R is compatible with the BiSS C interface. BiSS C is similar to SSI and can be used unidirectionally like SSI, and stands for Bidirectional interface for Serial/Synchronous.
Unlike SSI, BiSS C also supports bidirectional communication and operates at speeds up to 10 Mbits/sec. BiSS-C can address internal registers in the encoder that can be read by and written to by the master with data about the encoder or motor and controller. BiSS-C encoders can also carry other digital data (temperature, etc.) and transmit the data to the master on demand, without interfering with real-time operation.
This communications protocol is used by industrial automation devices and a common high speed reliable digital solution between absolute encoders and motion controllers.
