Sensor provider TE Connectivity (TE) has released a new magnetic encoder IC, the KMA36, which offers high resolution rotational or linear measurement in high temperature environments. TE is positioning the new magnetic sensor, with maintenance-free operation and high bandwidth, as a solution for dynamic Internet of Things (IoT) applications in harsh environments, such as industrial process control, robotics, exoskeletons, and medical device feedback.

The KMA36 has up to 15-bit (0.01 degree) resolution, and provides measurements over temperatures ranging from -13°F to 185°F (-25°C to 85°C) with a large air gap tolerance. The KMA36 includes a reduced power sleep mode over I2C and programmable parameters that provide options for a variety of configurations. Anisotropic Magnetoresistive (AMR) technology in the KMA36 enables contactless 360-degree measurement over an external magnet.

“At TE Connectivity, we continue to evaluate market trends and fulfill demand needs in the sensor industry,” said TE’s Michiel Boermans. “The KMA36 Magnetic Encoder IC is an excellent choice for applications where digital output and precise measurement are required. Complete with AMR technology, the KMA36 is a high-performing sensor that gives maximum design freedom and functionality for our customers.”
