Series R45 Rotopulser® Incremental EncodersSeries R45 Rotopulser® Incremental Encoders

Quick Specs…

  • Direct mount to NEMA 56C through 184C AC or DC motors
  • Field replaceable readhead for easy service
  • Complete electrical protection and proven noise immunity
  • Optional line driver outputs, screw terminal connections
  • Thin profile – only 5/8″ thick

Overview / Design Principle:

The separately mounted ring and gear are designed to function without any setup or adjustments. Operation is reliable even in wet, dirty, and extreme industrial temperature environments. No flexible shaft coupling is required, and there are no bearings to wear out, meaning greater mechanical reliability.

Coupled with a frequency-to-voltage converter, such as the Dynapar brand FV3, the R45 Rotopulser® provides a precise, brushless feedback, at a lower cost than expensive DC tachometer-generators.

An optional, X2 speed output provides twice the number of pulses per revolution for improved low speed operation. Line driver outputs are available for installations with long cable runs. A screw terminal option further simplifies field wiring. The Series R45 Rotopulser® comes with all necessary mounting hardware included.

Features and Benefits:

  • Unique hub design uses a split collar clamp that provides better gear retention than set screws and will not raise burrs on the motor shaft which can make removal difficult.
  • Thinnest package available, allowing more through shaft extension for clutches and brakes.
  • “Overhung” conduit box allows mounting to the rear accessory flange of larger motors without mechanical interference.

The Dynapar Advantage:

  • Innovative, high quality leading edge technology encoder products
  • Broad commercial – industrial grade product line
  • Fast 3 Day Delivery and customized built to order solutions available
  • Global Manufacturing & Service Support
  • Fast-Friendly Customer Service & Technical Support with Multi-Lingual Capabilities
  • Global Network of Authorized Resellers
  • Competitive Product Warranty: 2 Years

Applications:

The Dynapar brand Series R45 Rotopulser® mounts directly to motors with a front or rear 4-1/2 NEMA C-face to provide digital feedback for RPM readout, speed control, and positioning
