SLIM Tach® RL67 Incremental Rotary EncoderSLIM Tach® RL67 Incremental Rotary Encoder

Quick Specs…

  • Unique mechanical design for Reliance RPM™ motors
  • Rugged, zero-speed, magnetoresistive sensing technology is unaffected by grease, salt water, dust, and other common contaminants

Overview / Design Principle:

The hard anodized aluminum alloy frame provides strength, ruggedness, and corrosion resistance. The hardened encapsulated electronics offer outstanding reliability under heavy machine vibration and accidental impacts. The electronics range from +5 to +15 volts DC and include the latest in short circuit proof design on all output pins. High power, complementary, line driver outputs assure clean, crisp signals over long cable lengths. These outputs are compatible with most drives or other input devices. The advanced magnetoresistive sensing technology operates with an unparalleled immunity to grease, oil, salt water, dirt, fibers, and other contaminants. This eliminates the need to seal the encoder.

The compact SLIM Tach® RL67 adds only 1.5” to the motor length. Designed to maximize the ease of field installation, the RL67 retrofits onto older existing motors as well as new motors. In some cases, it may be necessary to change the accessory stub shaft in the motor. This stub shaft is also available from us.

The SLIM Tach® RL67 will mount directly in the 6.75” machined accessory recess of the 4.5” accessory flange found on the motor. This unique modular design mounts quickly and easily with no adapter plates, bearings, or flexible couplings. Installation can be completed in minutes, without gap adjustments or special tools. The encoder can be removed then reinstalled just as easily.

Features and Benefits:

  • Modular, bearingless, low profile “pancake” design adds only 1.5” to motor length
  • 5-15 VDC operation with bi-directional quadrature and signals, with high power differential line driver outputs
  • 64, 128, 256, 512, 1024 & 2048 pulses per revolution (PPR) with optional Index pulse
  • Up to 120°C operational temperature


The SLIM Tach® RL67 heavy duty encoder is a breakthrough innovation in feedback technology. Incorporating dual mounting features, the RL67 was designed especially for Reliance Electric, Inc. RPM® AC or DC motors.
