It is optimized for use in automotive, medical, industrial and consumer applications.

Application Field

The MM18-70ANS-ZCK Magnetic sensor is applicable for products in the automotive, medical, industrial and consumer industries. Automotive – This type of sensor is often used for proximity sensing, speed, and direction detection, allowing vehicles to better detect and interact with their external environment. Medical – Magnetic sensors are used in medical applications to detect the position of various body parts, such as fingers or toes. This data can be used to control medication pumps and body temperature regulators. Industrial – Magnetic sensors are used in industrial environments to detect positioning, proximity, and speed. This data is then used to control various processes. Consumer – Magnetic sensors can be used in consumer electronics such as tablets or laptops to detect movement and position.

Working Principle

The working principle of the MM18-70ANS-ZCK Position, Proximity and Speed (Modules) Sensor is based on Hall-Effect. Hall Effect is an electro-magnetic phenomenon linked to changes in the magnetic field. When an electrical current passes through a conductor such as a wire, a magnetic field is created. When this magnetic field is exposed to a material with a constant magnetic field, such as a permanent magnet, a detectable signal is created in the conductor. This signal can then be analysed to detect the position, proximity, and speed of an object.

The MM18-70ANS-ZCK Magnetic Sensor is designed to detect small changes in the magnetic field. An integrated Hall Effect Sensor together with a signal amplifier and a Schmitt Trigger is used. The Hall Effect Sensor tracks changes in the magnetic field strength, the signal amplifier amplifies the small electrical current which is detected by the Hall Effect Sensor, and the Schmitt Trigger stabilizes the signal and filters out noise from the detected signal. This allows for accurate and reliable measurements of the magnetic field.

Conclusion

The MM18-70ANS-ZCK Position, Proximity and Speed (Modules) Sensor is a popular choice for various applications in the automotive, medical, industrial and consumer industries. This type of sensor operates on the working principle of Hall-Effect and is designed to detect small changes in the magnetic fields, allowing for accurate measurements to be taken. It is an excellent choice for detecting speed, position, and proximity in applications ranging from motors to medical pumps.
