ASR022 noncontact TMR encoder sensors provide precise pulses indicating angular motion, and is more accurate and smaller than other non-contact encoders.
An ABZ interface allows the ASR022 to replace legacy optical encoders.
The sensor combines precise, low-power Tunneling Magnetoresistance (TMR) sensing elements with sophisticated digital signal processing.
The sensor is factory calibrated, with coefficients stored in internal memory.
The ASR022 is designed for harsh industrial or automotive environments with ESD protection, and full −40 °C to 125 °C operating temperature range.
ADT005-10E Rotation Sensors provide two binary digital outputs to accurately indicate the absolute rotational quadrant of a rotating magnet. The two outputs are 90 degrees out of phase to also provide directional information.
The ADT005 is higher hysteresis than the ADT002 for high noise immunity in applications such as speed sensing and counting rotations or where motion is in only one direction.
To minimize power, the ADT005 does not include
the high-field detection circuitry included in the ADT001 version, and is slightly less accurate due to lower-power circuitry.
The sensors use NVE’s unique Tunneling Magnetoresistance (TMR) technology to minimize power consumption and size.
The sensors are typically used with
radially-magnetized disk magnets or split pole magnet.
An Evaluation Kit is available with an angle sensor, magnet, circuit board with indicator LEDs, and a plastic magnet locating fixture.
Note: Please purchase in increments of 100 when purchasing quantities of 100 or more.
