Overview / Design Principle:

The shaft mounted MagCoder HS35M incorporates magnetoresistive technology making it immune to common contaminants such as grease, oil, water, and dirt. It fits a wide variety of motor shaft sizes and is a perfect choice for use in applications requiring accurate velocity feedback.

Its short circuit protection and reverse polarity protection prevent common causes of encoder failure. The MagCoder HS35M offers a variety of output voltage options, including the choice of regulated output, making it compatible with devices that accept only a specified voltage. An optional high powered line driver is available for further assurance of clear signals over long cable lengths. This unique driver is the strongest offered in the encoder industry.

The entire MagCoder HS35M rides on large motor style bearings, maximizing its operational life. Its flexible design allows the encoder to move axially, radially, and at a tangent. It is toughly constructed of stainless steel and epoxy coated zinc alloy. The simple design of the HS35M is pre-aligned, does not require user adjustments, and mounts without accessory hardware, further reducing installation cost and time.

Features and Benefits:

  • Short circuit protection and reverse polarity protection
  • 5-26 VDC operation with bi-directional quadrature and with high power differential line driver outputs
  • 128, 256, 512, & 1024 pulses per revolution (PPR) with optional Index pulse
  • Up to 80°C operational temperature


The MagCoder HS35M hollow shaft digital encoder is ideal for motor and machine applications at resolutions to 1024 PPR. Flexible mounting and adjustable anti-rotation arm, provide high tolerance of shaft vibration.
