A1145LLHLT Overview
Designed to protect magnetic switches from damage, the Tape & Reel (TR) package contains the switches. Safety precautions are taken by packaging the magnetic switches in SOT-23W packages. A good performance can be achieved with magnetic switches that can deliver 17mA as the maximum current. To make the switches work, they have 3 pins. This document contains 3 terminations. In order for this switch to function correctly, it should provide a maximum voltage of 24V. The switch normally supplies 12V to ensure reliable operation.
