NVE Introduces Noncontact ABZ TMR
Magnetic Encoder Sensor
PRAIRIE, Minn.May 4, 2020NVE Corporation today expanded its industry-leading
line of angle sensors with the new ASR022-10E ABZ TMR Magnetic Encoder Sensor.
The ASR022 is based on the same TMR sensor element and digital processing core
as the ASR002 SPI sensor and ASR012 I²C sensor, but with an industry-standard
ABZ encoder interface. The new part also provides a direction output.
More Rugged than Optical Encoders
The familiar ABZ interface allows easy replacement of optical encoders. But unlike
optical encoders, the new sensor is noncontact, has wide mechanical tolerances,
and is not susceptible to dust or contamination.
Small, Fast, Accurate, and Low-Power
With their unique TMR technology, ASR022 sensors are smaller, faster, more accurate,
and lower power than other magnetic encoders. Key ASR022 features include:
Ultraminiature 2.5 by 2.5 by 0.8 millimeter
High-speed 12500 samples per second
Precise 512 virtual lines (128 cycles) per revolution
Flexible 2.2 to 3.6 volt supply range
Low power four milliamps typical supply current
Robust airgap and misalignment tolerances
Full -40 to 125 degree Celsius operating range
ASR022-10E sensors are available now for immediate delivery, and priced at $2.22 each
in 1000-piece quantities.
The ASR022 Demonstration Board (part number AG964-07) is powered by two AAA batteries
(included) and includes an ASR022-10E sensor, a magnet assembly, magnet fixturing,
a four-digit display to indicate rotation, and light-emitting diodes (LEDs) to indicate
the sensor outputs. Boards are priced at $195 each.
