XT45 severe duty hollow shaft magnetic incremental quadrature rotary encoders fit shafts up to 1 1/8" [30mm]. For even larger shaft applications up to 2 3/8" [60mm], M6 models are available.
The XT45 is built to withstand extreme conditions: Cold, heat, shock, vibration, oil, salt water, and electrical overloads. XT45 is ideal for non-hazardous oil drilling applications such as top drives.
We started with our Wide-GapTM magnetic sensor system, potted to protect against liquids and dirt. We added universal 5-24V operation and high power outputs protected against short circuits and wiring problems.
Then we built an ultra-rugged shaft assembly with huge bearings and 2000lb shaft clamping to hold tightly and keep turning smoothly, even under continuous shock and vibration.
This incredible mechanical and electronic engine is protected by a cast aluminum housing and non-contacting labyrinth seals that work in any orientation. Of course, the XT45 features diagnostics and a remote alarm contact so you are certain your XT45 is providing top-quality signals.
XT45 keeps your rigs drilling and your machines running!

Product Glossary

  • A Quad B

    A Quad B refers to the set of output quadrature signals from an incremental quadrature encoder to indicate speed and direction, including complements: A, A NOT, B, B NOT (, , , ). Most Avtron encoders offer A Quad B output at no extra cost.  For more information on quadrature- Wikipedia: http://en.wikipedia.org/wiki/Quadrature_phase

  • Anti-Rotation Arm

    A device used to prevent hollow shaft encoders from spinning with the shaft rotation. It is also called a tether or a torque arm. To prevent encoder bearing damage, anti-rotation arms are very flexible and permit all movements, including axial shaft movement but not rotation.

  • Axial Shaft Movement

    Motor shaft movement in or out, relative to the ends of the motor. Often motors that use roller or sleeve bearing construction have more axial shaft movement. Most Avtron modular encoders tolerate +/- 0.050" of axial movement maximum. Use hollow shaft encoders for high axial movement motor styles, such as MD motors. Most competitors’ modular encoders tolerate much less axial movement than Avtron products.

  • Encoder

    A device which indicates position and speed via a set of digital outputs. Incremental encoders output quadrature (A Quad B) signals, and may add a marker pulse once per revolution.  Absolute encoders typically indicate position via a digital message, a set of parallel outputs, or analog values.

  • Magnetic Encoder

    Magnetic and magnetoresistive encoders typically use a magnetized rotor with north and south poles lined up around the perimeter of the disk. A magnetoresistive sensor detects the transitions, and these are the counts or pulses generated by the encoder. Magnetic encoders withstand dirt, dust, water, and temperature changes far better than optical encoders.

  • MS Connector

    The most used encoder connector style in North America. Available in 6, 7, and 10 pin versions, with 10 pins being the most common. Avtron offers pin-for-pin exact replacements for competitors’ models using MS connectors. MS connectors are extremely reliable but require soldering. Many users prefer industrial EPIC ® style connectors instead. EPIC® is a registered trademark of the Lapp Group.

  • Severe Duty

    Severe Duty encoders have the best ability to withstand temperature cycling, extreme temperatures, contaminants, bearing loads and physical abuse.

  • Wide-Gap Technology

    Avtron encoders use special optical sensors and magnetoresistive sensors, combined with proprietary circuit designs to allow the sensor to be located much farther from the magnetic rotor or optical disk. This eliminates sensor crashes and makes mounting easy and forgiving of mechanical variation.
