PD50 – Auto Stop System

Automatic/semi-automatic length stop gauge featuring a heavy-duty rack and pinion drive system.

The Kentucky Gauge PD50 allows you to improve cut accuracy, eliminate mistakes and increase part yield. Equipped with a rack and pinion drive and a high-accuracy, non-contact linear encoder, the PD50 is built to last and ready for integration with any new or existing production and fabrication equipment. Eliminate setting manual stops and setup time completely with the PD50 automatic length stop gauge.

The PD50 is perfect for any ferrous and non-ferrous fabricating equipment:

  • Cold Saws
  • Upcut Saws
  • Column Saws
  • Band Saws
  • Drills
  • Ironworkers
  • Punch Presses
  • Shears
  • Press Brakes
  • Custom machinery and more!

Key Features

5-Micron Linear Encoder - Non-Contact and Wear-Free

5-Micron Linear Encoder – Non-Contact and Wear-Free

Our linear encoders boast a resolution of 0.005mm, allowing you to achieve unparalleled length accuracies. The non-contact nature of these encoders ensures high-accuracy measurements for a lifetime.

Unlike rotary encoders, there are no moving parts. All the mechanical components found in rotary encoders (flange, shaft, bearings, etc.) are not needed, which eliminates mechanical failures.

Rack and Pinion Drive - Rugged and Reliable

Rack and Pinion Drive – Rugged and Reliable

Unlike belt drive systems, our rack and pinion drive isn’t prone to wear or fatigue. Moreover, we’re not limited by the belt length. We can build the PD50 to measure ANY LENGTH that you require.

Fully Programmable with I/O's for any Equipment or Tool

Fully Programmable with I/O's for any Equipment or Tool

Our controllers are fully programmable to do exactly what you need them to do. The controllers are simple to program at the keypad without requiring specialized training. If you require nesting and optimization, programs can be optimized using Excel and downloaded to the controllers using our supplied software.

We also include a free-standing controller stand that allows you to place the controller where it’s most convenient for your operators.
