The Danaher / Dynapar / NorthStar SLIM Tach SL85 Magnetoresistive Encoder is a breakthrough innovation in feedback technology. This high resolution, bearingless encoder is optimized for AC vector motor applications. The model SL85 provides resolutions of 512, 1024, or 2048 pulses per revolution, much higher resolutions than traditional gear tooth ring kits.

The magnetoresistive sensor of the SL85 operates with an unparalleled immunity to grease, oil, salt water, dirt, fibers, and dust, thereby eliminating the need for sealing. The sensor generates A and B phase quadrature signals and their complements (A & B). The module provides transient and noise suppression, reverse polarity protection, and operates with DC power from +5 to +15 volts. A high power, complementary, line driver output assures clean, crisp signals over long cable lengths. The hardened encapsulated electronics of the SL85 make it especially resistant to heavy machine vibration and accidental impacts.

The rugged construction of the SL85 offers the user wide flexibility in a variety of applications. The SL85 occupies only 1.250” of the motor shaft length, enabling the encoder and a flexible coupling or pulley to be mounted on the motor. The simple and sturdy design can be mounted in any attitude quickly and easily. Mounting the SL85 onto the 8.5” (180 C) face of a motor is quick and easy with no adapter plates, bearings, or flexible coupling. Installation can be completed in seconds with no gap adjustments or special tools. The encoder can be removed then reinstalled just as easily. The latching industrial connector requires only a simple screw driver to install. To replace a module, simply remove four screws and replace with a new module. No electrical adjustment or alignment is required.

The SL85 pulse wheel assembly is imprinted with magnetic poles that provide higher pulse counts than traditional gear tooth wheels. The higher resolution provides greater accuracy and more precise speed control in your applications. For flexible usage, wheel assemblies are available in a variety of mounting configurations. They are manufactured using a rugged material capable of withstanding hot, wet, and dirty environments.
