Intelligent Sensing Solutions

Sensors are widely used in many different applications. In many instances, sensor technology has become a fundamental enabling technology. Surging interest in sensors has been driven by numerous applications, such as intelligent manufacturing processing, automotive, healthcare, etc., in which sensors can provide a large benefit. Sensors are of great importance in safety-related areas too.

Murata’s sensors have been designed and developed by specifically targeting applications that require high precision and high reliability. Our sensors have great potential for other wider ranging applications and high hopes for the future.

AMR Sensors (Magnetic Switches)

Exploiting the magnetoresistive effect, AMR sensors have an IC to detect changes in the magnetic resistance of a magnetoresistive element affected by an external magnetic field.

Murata AMR sensors are used for cylinder position detection, smart meter, and open/close detection for equipment (e.g. video cameras, refrigerators, etc.). Murata braod lineup of AMR sensors come with different package sizes and sensitivity ranges.

Position/Rotation Detection: This series of versatile sensors can detect a broad range of magnetic movements - position sensing and rotation detection. The great diversity offers customer a choice of AMR sensors ideal for the conditions of their environment of use (e.g. temperatures, sensing movement , supply voltages, etc.).
Rotation Dectection: This series of AMR sensors features stable output characteristics. They are ideal for the precise detection of rotational displacements.
Applications:: AMR sensor is one of the best fits for its usage such as non-contact switches for mobile devices.

Open/Close detection: - Digital cameras, mobile phones, notebook PCs, etc.
- Refrigerators, washing machines and other home appliances
- Security equipments (doors/windows)
Rotation detection: - Smart gas meter

Ultrasonic Sensors

Ultrasonic sensors emit ultrasonics waves in the air that reflect off of objects. The reflected sound is then received by the sensor. This technology is used for detection of objects in burglar alarms and automatic doors as well as for range measurement in automotive parking assistance systems.

Using its unique piezoelectric ceramics manufacturing technology developed over many years, Murata has developed various types of ultrasonic sensors which are compact and yet have very high performance.

Features:: 1. Compact and light-weight
2. High sensitivity and high sound pressure
3. High reliability
Applications:: - Intrusion alarm systems
- Backup sensor for automotive
- Factory automation equipment
