OH49E Analog Hall Effect Sensor

The OH49E Analog Hall Effect Sensor is a highly sensitive magnetic field detector with an analog voltage output that varies linearly with the strength of the magnetic field. This makes it a versatile choice for a wide range of applications including position detection, RPM measurement, current sensing, and contactless switching.

Packaged in a standard TO-92 form factor, this sensor is easy to mount on PCBs using through-hole technology. Its high sensitivity, fast response time, and low-noise operation make it ideal for dynamic environments like automotive systems, robotics, and embedded electronics. Designed to operate within a wide temperature range and voltage input, it ensures reliable performance under tough industrial or consumer settings.
