element14 Pty Ltd introduces Honeywell’s nanopower anisotropic magnetoresistive sensor ICs designed to provide the highest level of magnetic sensitivity, as low as 7 Gauss typical, while requiring nanopower up to 360 nA in value.
Smaller, more durable and more reliable than reed switches, Honeywell’s new nanopower sensor ICs operate with the same sensitivity for the same cost. The new sensor ICs from Honeywell can replace reed switches in battery-powered applications with low power requirements and large air gap needs.
Suitable for use in a wide range of battery-operated applications including water and gas meters, electricity meters, industrial smoke detectors, exercise equipment, security systems and scanners, the new sensor ICs are also ideal for white goods such as dishwashers and refrigerators, medical equipment such as hospital beds and infusion pumps, and consumer electronics such as computers and tablets.
The omni-polar sensor ICs can be activated by a north or south pole, eliminating the need to identify magnet polarity and reducing system cost by simplifying the installation process.
Honeywell’s new sensor ICs do not require external resistors for the push-pull (CMOS) output, simplifying operation for engineers. Electrical noise generated by the sensor is eliminated thanks to a non-chopper stabilised design. The subminiature SOT-23 surface mount package, supplied on both tape and reel is smaller than most reed switches, allowing for use in automated pick-and-place component installation that reduces production costs.
The sensor IC is available in two magnetic sensitivities: ultra-high sensitive SM351LT (7 Gauss typical operate, 11 Gauss maximum operate, 360nA current draw) and very high sensitivity SM353LT (14 Gauss typical operate, 20 Gauss maximum operate, 310 nA current draw).
Honeywell’s sensor ICs are the latest additions to element14’s impressive line of durable, reliable switch and sensor solutions.
