Detecting
Tiny Gear Teeth |
|
|
ABL-Series Gear-Tooth
sensors can detect sub-millimeter pitch gear teeth. We did a demonstration to
prove it to skeptical customers.
We use an ABL006 Gear-Tooth sensor biased by an inexpensive ferrite magnet.
A high-speed motor spun a fine-tooth gear, and we could vary the motor speed.
A digital meter displayed the speed measured by the sensor, and a microcontroller
ran the motor and read the sensor.
The demonstration gear was module 0.26 mm; the pitch was 0.83 mm, and
tooth depth was only 0.55 mm:
The sensor provided accurate speed measurement from DC to 10,000 RPM. This requires
a fast, sensitive sensor, and ABL Gear-Tooth sensors fit the bill.
Key features and specifications include:
• Sensitive to small teeth
• 1 MHz operating frequency
• Single- and dual-bridge versions
• Up to 30 V supply
• 150°C operating temperature
• Miniature MSOP8 and 2.5 mm x 2.5 mm TDFN6 packages

An article on magnetic
angle sensors and magnets in Magnetic Business & Technology:
“TMR sensors are more sensitive and have wider operating field ranges
than Hall-effect sensors.”

A paper in the latest edition of the IEEE Sensors Journal, titled “Non-Invasive
Measurement of Glaucoma Disease at Earlier Stage Through GMR Sensor AH Biomagnetic
Signal From Eye and RADWT Algorithm,” describes NVE sensors to measure
the biomagnetic signal of the aqueous humor for glaucoma detection.
