Description

The THIN-LINE series of rotary pulse generators, (also known as incremental encoders and digital tachometers) consists of three models: M56, M67, M85. All three have the same rugged magnetoresistive sensing circuit, but each has a different mechanical configuration in order to fit the most popular AC and DC motors.

Features

• No Bearings or Couplings
• 57% Larger Air Gap
• Lower Installed Cost
• Thin Profile

Outputs

The standard electrical output from a THIN-LINE pulse generator is a two phase, square wave signal with complements (A,A\, B,B\). A once per revolution marker pulse (Z,Z\) is included on all units. The choices of pulse per revolution (PPR) ratings include 128, 256, 512, and 1024.

Motor Mounting Options

THIN-LINE pulse generators can be easily installed on most AC and DC motors equipped with accessory mounting faces. The standard mounting face diameters are 4.50″, 6.75″, and 8.50″. The accessory face can be machined directly on the motor or it can be machined onto a fan cover.

All three models are modular designs consisting of two basic components, the rotor and the stator. This design simplifies the installation and eliminates time consuming alignment procedures. Also, a modular pulse generator has no bearing, no couplings, or other wearing parts, making it one of the most reliable configurations available.

WIDE-GAP Sensor Technology

The quality of the electrical signal generated by a magnetoresistive pulse generator depends upon the proper air gap between the sensor and the rotor. To improve the performance and ensure proper operation of the THIN-LINE pulse generators, Avtron uses a new, Wide-Gap sensor.

The Wide-Gap sensor technology that is used on the M56, M67, and M85, has several advantages over conventional magnetoresistive sensors, the most beneficial of which is a 57% larger operating air gap between the sensor and the rotor.

Another feature of the new sensor technology is Edge-Guard. The Edge-Guard sensor is mounted perpendicular to the rotor, which protects the critical sensor elements.
