Motor Coil Temperature KTY Sensor

Description

In the motor control loop, there are several types of sensors that provide feedback information. These sensors are also used to detect fault states that may damage the system, thereby improving system reliability. The role of sensors in motor control is particularly important, especially in current detection amplifiers, Hall sensors, variable reluctance (VR) sensors, and motor coil temperature sensors.

Temperature sensors are used to measure the temperature of automotive motor coils. The sensor chip has linearity and long-term stability, and the temperature resistance characteristic curve is customized for the customer's measurement system equipment. The chip and wire are crimped together and protected and enclosed by insulating material.
