A1143LUA-T Overview
ldeally, the magnetic switch should be packaged in the Bulk for protection against damage. The magnetic switches are put into 3-SSIP packages for safety protection. The magnetic switches are capable of supplying 17mA as their maximum current. The document has 3 terminations. Switches like this should supply voltages no higher than 24V. It is normal for this switch to supply 12V voltage for reliable operation. This magnetic switch can provide a voltage of 3.5V as its minimum voltage.
