Dynapar has an announcement! In the coming months, Dynapar will replace the NorthStar SLIM Tach HS60 (part numbers beginning with H6 and D6) with its successor: the RIM Tach NexGen HT55 encoder. Sadly, the SLIM Tach HS60 has reached its end-of-life.

The RIM Tach NexGen HT55 encoder is a released product and is now available for order. Here are links to the Data Sheet and Installation Manual. All other technical specifications and dimensions are available on the Dynapar website. Here are the

Series HT55: New and Improved!

Change often comes with improvement. So, here are the many technical benefits that the NorthStar HT55 model provides over the HS60:

• The HT55 is best-in-class! Its reliable magnetic hollow shaft encoder with heavy-duty bearings improves performance for TEFC AC motors.
• NorthStar has redesigned its diagnostic LED indicator. Now, the HT55 offers a real-time visual indication of successful power to encoder and encoder output.
• Upgraded line driver and on-board diagnostics deliver unfailing encoder output over long distances.
• It is compact in design! This means a higher operating temperature range, higher shock resistance, more top shaft speed, and higher frequency response rating.
• Expanded resolution up to 4096 PPR is now available.
• Accommodates more extensive shaft size range from 1/2” to 2-7/8”.
• It has a robust and durable stainless steel and anodized aluminum construction.
• Single or dual isolated outputs available with field-serviceable connector.
