Net Forward Encoder Interface

Electro Cam Corp. is pleased to offer this sneak preview of our new PS-2252-12-TP1 Net Forward Encoder Interface (NFEI). Ideal for applications requiring perfect alignment, the NFEI eliminates erroneous encoder pulse counts caused by uncontrolled backward movement, and counts forward pulses until reverse motion occurs. It then stops counting pulses (reverse or forward) until encoder position exceeds the last forward position before reverse.

For example, when a web process stops, some backward movement will occur. Upon re-start, the process will overlap a portion of the web, resulting in mis-registration. The NFEI counts pulses until reverse occurs, then withholds pulses until the exact point the process stopped, resulting in perfect registration! If the process stops halfway through a character, the character will be finished when the process restarts. Scrap is eliminated and downtime is reduced.

The new NFEI works with standard quadrature encoders.

Applications include:

• Web Processes
• Printing
• Bar Codes
• Conveyors
• De-Reelers
• Wire & Cable Cut-Off
• Labeling & Packaging Equipment
• Any application requiring absolute registration
