A1180LUA-T

The A1180LUA-T from Allegro MicroSystems is a magnetic interface Hall-effect device that integrates magnetics, logic and latches into a switch. As a zero-speed magnetic switch, the A1180LUA-T provides an output signal of either high impedance open or low impedance closed contact states. The logic output requires no external pull-up or pull-down resistor and is capable of sinking as much as 10mA. The switch has no internal connections, therefore, provides a reliable, contactless closed or open response.

Features of the A1180LUA-T

• Wide operating voltage range from 4.5V to 16.5V
