A lineup of various sensors respond to the sensing needs of various applications for automobile, wearable, medical care and health care.

Termperature Sensor

Capable of sensing heat, temperature sensors are widely used to protect equipment and circuits.
NTC thermistors are elements whose resistance falls with an increase temperature, while PTC thermistors display an increase in resistance as temperature rises. Their characteristic temperature-resistance curves allow them to be used as temperature sensors.
NTC thermistors find a wide range of uses since they feature high precision and good thermal response. PTC thermistors are employed in many applications that detect certain temperature levels using extremely simple circuits.
Murata thermistors come in chip and lead types.

Ultrasonic Sensors

Ultrasonic sensors emit ultrasonic 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. 

Infrared Sensors

Pyroelectric infrared sensors detect infrared rays using the pyroelectric effect of pyroelectric ceramics, a kind of piezoelectric ceramics.

Shock Sensors

Based on long unique piezoelectric ceramic technology in-house, Murata shock sensors are developed unique and high performance acceleration sensors used for detecting vibration and impact (mechanical shock).

Accelerometers

Murata is the global market leader in low-g acceleration sensors for automotive applications. The extensive accelerometer product range includes high performance digital and analog accelerometers for both safety critical automotive and industrial applications. Murata accelerometers are based on the company's proprietary 3D MEMS technology and they offer a number of excellent product features and benefits for the most demanding applications. The sensing element and the measuring ASIC are assembled in a dual-in-line or dual-in-flat-line plastic package with pins for surface mount and re-flow soldering. They are environmentally protected with silicone gel resulting in excellent performance and reliability in a humid environment and at temperature cycling. In addition, the robust sensing element design with over damped frequency response enables excellent performance even in harsh and vibrating environments. The measuring direction is parallel or perpendicular to the mounting plane. The ASIC includes an on-chip EEPROM memory with the calibration coefficients for unit interchangeability. Murata accelerometers include enhanced failure detection: digitally activated self-test, calibration memory parity or check sum check and continuous connection failure detection. The products are intended for horizontal or vertical measurements.The zero point temperature dependence is less than 1mg/°C.

Inclinometers

Murata inclination sensors are an optimum choice for high accuracy leveling and inclination measurement instruments. The highest accuracy is available with SCA103T series that use differential measurement principle to compensate all common mode error and noise effects.

The best shock durability of the MEMS market provides trouble-free measurements in moving machines, vehicles, airplanes, construction machines and hand held devices.

Gyro Sensors

Murata Electronics develops and manufactures gyroscope components and combined sensors (including gyroscope and accelerometer) based on the company's proven 3D MEMS technology and highly integrated electronics.

Industrial gyroscopes offer a performance level that typically has been available only for expensive module products. Sensing elements and the measuring circuitry are assembled into a pre-molded plastic dual-in-line (DIL) package, protected with silicon gel and covered with a stainless steel lid. All products are RoHS compatible and suitable for lead free reflow soldering.

Rotary Position Sensors

A category of position sensors, rotary position sensors can measure rotational angles from output voltages. The principle: The rotation to be measured is linked to the motion of a slider to cause changes in resistance, which the sensor circuit converts into changes in output voltage. Unlike trimmer potentiometers, rotary position sensors are extremely durable due to their high rotational life characteristics.

AMR Sensors (Magnetic Sensors)

These products are magnetic sensors using AMR elements whose resistance varies according to the strength or direction of the magnetic field. Combination with a magnet permits non-contact rotation detection or position detection.
