The LC-2 is an ON/OFF Electronic Limit Switch

Sensing vertical movement in a slack loop of conductive material. Spring probes maintain smooth stock delivery between the adjustable upper and lower limits.

The LC-3 is a Proportional Loop Control

Designed to interface with a variable speed AC or DC drive. The drive changes speed automatically in response to signals from the touch probes for smoother payoff and take-up. The LC-3 can also be converted to a No-Touch Sensor System with the use of proximity sensors, which are available upon request.

 

 



 

Reduce Die Breakage and Machine Downtime

Prevent the smashup of ONE die and this sensor pays for itself. The P/A Stock Detector uses a resistance-sensing controller to monitor material position as it enters the press or moves through the die.

The Stock Detector Operates Through Customer-Supplied Contact Senors

Or probes to signal either an Emergency Stop or Top Stop of the press. Stock buckling, run-out, and misfeeds are detected before a serious problem develops. P/A will help you select the probes and sensors best suited to your application.

 



 

The RF System Uses a Shielded Antenna

And a Radio Frequency Field to sense conductive material. As the loop changes height, the radio signal changes in response causing the variable DC drive of the Reel or Straightener to maintain a constant loop.

The RF System

Is not susceptible to Ultrasonic interference which makes it an attractive alternative to sonar sensing systems.

 

 



 

The P/A Ultrasonic Loop Control Utilizes Sonar, Or "Echo Location"

To determine and maintain a constant loop height. This gives the operator the flexibility of using the longer loops required when stamping long progressions.

Microprocessor-Based Control Eliminates Signal Drift

While the coded sound bursts reject interfering sound waves.
