Honeywell sensing technology takes wireless detector design” to new levels”

Honeywell has introduced a new device that allows the manufacturers of fire and security detection technologies to design smaller, less obtrusive wireless-based products without sacrificing reliability or performance. Solutions in the new Anisotropic Magnetoresistive (AMR) Sensor ICs, Nanopower Series have higher sensitivity and more reliability than ‘traditional’ sensors yet consume less energy. They’re also smaller and therefore allow greater flexibility in design at a lower cost. Typical product applications include smoke detectors and door/window alarms. In the case of the latter, the sensor will immediately send a signal to a wireless module which then transmits that signal to a central control unit for processing as soon as a door or window is opened, removing the magnet out of the sensor detection range. On smoke detectors, the sensor is used as an alarm test switch where an external magnet is brought into the detection range of the sensor to check correct operation. Smaller, more durable and reliable than reed switches, at the same sensitivity and essentially the same cost, the new AMR Sensor ICs, Nanopower Series is ideal for battery-powered applications where previously only reed switches could be used due to very low power requirements and large air gap needs. Nicholas Roche, product leader at Honeywell Sensing and Control, states that the new Nanopower technology is a game changer.” It’s highly sensitive,” explained Roche,” and more reliable than ‘traditional’ switches that can break and tend to be less stable over time.” Roche added:” Most important of all is the fact that our new AMR Sensor ICs consume less power which means batteries need to be replaced less often” a major advantage to manufacturers and installers alike. This overcomes one of the major hurdles regarding the wider take-up of wireless detectors.” The sensors are designed for use in a wide range of battery-operated applications. They can also be used in medical equipment for hospitals, medication dispensing cabinets, infusion pumps and for consumer electronics such as notebook computers, tablets and cordless speakers.
