Murata Reduces Size of AMR Magnetic Switches
Murata Electronics North America introduced its smallest anisotropic magneto resistance (AMR) switch to its product portfolio. Measuring only 1.0 x 0.9 x 0.5 mm, the AS series is ideal for open/close detection in white goods (home appliances such as refrigerators and dishwashers), security equipment and other consumer electronics including cell phones, laptops and digital cameras. Murata's magnetic switches are a cost-effective replacement for traditional mechanical switches, which typically have wear and tear problems over the life of the product. Murata's more reliable magnetic switches are also designed to be waterproof, which is especially appealing to white good manufacturers.
"Demand for magnetic switches is expected to increase as equipment makers look to replace larger and less reliable mechanical switches," said Peter Tiller, Senior Group Product Manager for Murata Electronics North America. "Murata's materials expertise allows us to produce quality magnetic switches that meet current and future design needs."
The AS series complements Murata's comprehensive lineup of AMR switches that features industrial standard package sizes such as the SOT23 and the SON4 series. Murata's switches come in both high (1.5mT) and low (3.0mT) sensitivity models making them suitable for a wide variety of applications. The switches also feature low power consumption, as they require only 1.6 µA/1.8 V or 4.7 uA/5 V. Murata's AS switches are available for 25 cents per 10,000 pieces. Lead time is approximately 12 weeks.
