<h2>Overview</h2>
<p>The <strong>Allen-Bradley 100-SA02</strong> is a side-mounting auxiliary contact block manufactured by Rockwell Automation. This compact accessory provides additional contact functionality for standard industrial contactors and control relays. With its straightforward 2 NC (normally closed) configuration and screw terminal connections, the 100-SA02 is ideal for adding logic or status signal capability to existing contactor assemblies without requiring major control system redesign.</p>
