The Rugged Model 30M Fits into Tight Spaces

We don’t get many walk-ins in our Sagle, Idaho, headquarters. So when Brad Newman of  Newman Brothers Logging came through our door with his equipment in hand, it was an interesting day for our technicians. When Brad came in, he said,  “I’ve got this log follower from my Kesla 30RH that needs a really small encoder. Can you guys help us out?”

Of course we can!

In this machine, the encoder is in the roller part of the processing arm, the log follower. (See photo at right.) That part rides along the log, and the encoder sends a digital pulse back to the controller, so the machine cuts the log at the correct length. (Here's a video of the Kesla 25RH in action, very similar to the 30RH.)

The right encoder for this job would need to meet some very specific requirements:

  • First and foremost, it’ needed to fit into a tight space. The encoder would have to be very compact – no more than an inch in diameter.
  • It would have to be rugged enough to operate in backcountry logging equipment, surviving temperature extremes and all the elements. 
  • It had to be able to take a lot of bounce and movement and still provide reliable feedback.
  • This application called for bidirectional feedback, so the right encoder had to offer Quadrature.
  • The existing controller required Open Collector output, so the encoder needed that output option.

After considering all the needs of this application, there was one, obvious, perfect solution: the Model 30M Magnetic Encoder Module.

At just 30 mm in diameter, it is definitely compact enough. With the optional IP69K seal, it is certainly rugged enough. And with the 30M's various options, it is highly configurable. So we were able to find exactly the configuration needed to get the log processing machine up and running again.

Brad was back out the door, with his log follower operational, later that day.
