ABL005

The ABL Series GT Sensors are differential sensor elements that provide an analog sinusoidal output signal when used with a bias magnet and gear tooth or a magnetic encoder. These chips use NVE's proprietary GMR sensor elements, featuring an extremely large output signal from the raw sensor element, which is stable over the rated temperature and voltage range. As a result, ABL Series GT Sensors feature excellent airgap performance and an extremely stable operating envelope, as well as the robust reliability characteristics that NVE sensors are known for.

Three different standard spacings are available, for use with fine and coarse pitch encoders and gear teeth. Both single bridge and double bridge configurations are also available; double bridges are used to generate sine/cosine outputs. In addition to the standard spacings, NVE can provide custom spacings and multiple sensor elements tailored to the individual customer's application for a nominal design and tooling charge.

Contact NVE for further details. For digital output applications, these sensors can be used with NVE's DD001-12 signal processing IC, which converts their output into a 50% duty cycle modulated current signal. This IC allows placement of the ABL sensor in a very small housing, with wires running from the sensor to the signal processing IC in a remote location. In this fashion ABL series sensors can be used in M8 and smaller housings.
