A3144
by JSMSEMI(杰盛微)
A3144 is a Hall-effect switch from JSMSEMI, used to detect a magnetic field without mechanical contact. In a board design it can provide a digital sensing point for magnet position or proximity, with only three connections at the symbol and footprint. The free verified KiCad set includes the three-pin symbol, SOT-23-3_L2.9-W1.6-P1.90-LS2.8-BR-CW footprint with three SMD pads, and a 3D model. The converted import has been used by 1 ProtoFlow engineer in real designs, supporting the editor mapping. This sensor can be opened directly in ProtoFlow.
