Murata announces world's smallest pyroelectric infrared sensor

Hoofddorp, Netherlands: The latest version of Murata's pyroelectric infrared (PIR) sensor is the world's smallest at just 5.0 x 4.7 x 2.4 mm, enabling the sensor to be used in compact, low profile electronic devices and equipment. The IRS-B210ST01-R1 is also the only surface-mount PIR sensor on the market. It features high sensitivity and signal to noise ratio, excellent stability against temperature changes and white light and enhanced RFI immunity.

Murata's long lead thermistor for hard to reach areas gains automotive qualifications

Hoofddorp, Netherlands: Murata's Thermo-String long lead thermistor range for monitoring the temperature of areas that are hard to reach with surface-mount thermistors is now fully qualified for automotive use. Hot spots may not always be on the PCB or motherboard, so Thermo-String's long leads of up to 150mm allow the head of the thermistor to be situated as close to the problem area as possible, even in narrow or small locations.

Murata reduces the size of its AMR magnetic switches for open/close detection in consumer electronics

Hoofddorp, Netherlands: Murata has reduced the size of its AMR magnetic switches, saving space and cost in consumer electronics applications. AMR (Anisotropic Magneto Resistance) magnetic switches are primarily used for open/close detection in home appliances such as white goods and security equipment as well as other consumer electronics devices like mobile phones, laptop PCs, digital cameras etc. Murata's range of AMR switches is now available in an ultra small package measuring 1.0x0.9x0.5mm, in addition to industrial standard package sizes such as SOT23 and SON4.

Murata's PRF thermistor series protects power FETs in multiple locations in POL converter applications

Hoofddorp, Netherlands: The latest addition to Murata's PRF family of chip ceramic thermistors (POSISTORs) is the PRF18xx5RB series, designed for overheat detection of power FETs in point of load (POL) DC-DC converters and other power supply applications. Each part has two temperature sensing points and features characteristic curves that rise very sharply. The series has a resistance of 470Ω at 25°C, rising to 4.7kΩ between 65 and 145°C, rising further to 47kΩ between 80 and 150°C, depending on the part number. The PRF series is available in tiny 0603 packaging, and is also suitable for detecting overheat conditions in battery packs, motors, power devices and other systems.

Murata’s SMD pyroelectric infrared movement sensor saves board space

Hoofddorp, Netherlands: Murata’s surface mount pyroelectric infrared (PIR) movement sensor is now available in a surface mount package that is both smaller and lower cost than its thru-hole counterpart. Murata’s IRS-A200ST01-R1 SMD PIR sensor is constructed with H shaped electrodes, as is the through-hole version, the IRA-E700ST.

Murata pattern recognition sensors for compact banknote readers have excellent gap characteristics

Hoofddorp, Netherlands: Murata has released four new products in its BS05 series of magnetic pattern recognition sensors. The BS05M1HFAL, BS05M1KFCA, BS05M1KFFA and BS05M1KFBB magneto-resistive sensors are designed for ATMs, banknote counters, detectors and other validator applications. The devices are suitable for detection of magnetic thread or magnetic ink, and enable simple and quick mounting. These parts retain around 70% of their output voltage at a 0.1mm gap between sensor and substrate, compared to just 4% for typical coil head sensors. Along with their stable frequency characteristic, which is independent of the scanning speed, this makes them suitable for high-speed processing devices that demand superior accuracy.
