A1101LUA-T Overview
This Bulk package protects the magnetic switch from damage. For safety reasons, magnetic switches are packaged in 3-SSIP packages. When these switches are working, 25mA is the maximum current they can output. It is possible to supply 7.5mA current with these switches. During operation, the switches have 3 pins. In total, 3 terminations have been recorded. Switches should generally produce 20mA current. Normally, this switch should supply a maximum voltage of 24V. The switch normally supplies 12V to ensure reliable operation.
