00:00:02.880 --> 00:00:06.033
We're at the Angst+Pfister booth at 
Sensor Test.

00:00:06.364 --> 00:00:08.895
Angst+Pfister is a leading NVE distributor,

00:00:09.226 --> 00:00:15.086
and they're demonstrating 
an NVE ABT series TMR gear tooth sensor.

00:00:16.936 --> 00:00:23.680
As shown on the laptop, the sensor provides sine 
and cosine outputs, with one cycle per tooth.

00:00:24.560 --> 00:00:28.608
This allows micron-range position sensing
for a rack gear like this,

00:00:29.028 --> 00:00:32.678
or a thousandth of a degree resolution for a round gear.

00:00:33.698 --> 00:00:37.660
Large output signals allow direct
interface to microprocessors.

00:00:38.620 --> 00:00:43.500
The sensor is back-biased with 
a small magnet and connected to an Arduino.

00:00:45.440 --> 00:00:49.385
These are dual-channel sensors consisting of 
two passive Wheatstone bridges

00:00:49.625 --> 00:00:53.505
made with NVE state-of-the-art TMR technology.

00:00:54.284 --> 00:00:57.320
Back biasing allows the sensor
to detect gradients

00:00:57.320 --> 00:01:00.000
from passing ferromagnetic gear teeth.

00:01:01.621 --> 00:01:05.841
The sensors are pitch matched
to the gear for optimal performance.

00:01:09.220 --> 00:01:14.820
The ABT series covers a wide range of pitches, 
from tiny gears for miniature robotics

00:01:15.060 --> 00:01:17.720
to large gears in heavy machinery.

00:01:18.500 --> 00:01:20.258
Other features include:

00:01:20.498 --> 00:01:22.937
micron range resolution,

00:01:23.300 --> 00:01:25.722
large output signals,

00:01:26.022 --> 00:01:29.097
low hysteresis for excellent repeatability,

00:01:29.697 --> 00:01:33.137
and low noise to enable ultra high resolution.
