<h2>Overview</h2>
<p>The <strong>Conveyor Components CMS-1G</strong> is a compact motion detection switch engineered for real-time monitoring of conveyor belt systems and rotating equipment. This NEMA-rated sensor provides direct-drive control to detect when machinery has ceased rotation, triggering protective shutdown or alarm signals.</p>
<h2>Key Features</h2>
<ul>
<li>Compact motion sensing control with integrated mechanical and electronic components</li>
<li>Double Pole Double Throw (DPDT) relay rated for 3A @ 120VAC, 240VAC, and 480VAC</li>
<li>Bi-directional sensing—detects motion loss in either clockwise or counterclockwise rotation</li>
<li>Maximum operating speed of 1000 RPM with 12-segment brass encoder disk</li>
<li>NEMA 3S, 4, and 4X enclosure ratings for washdown and corrosive environments</li>
<li>IP65 compliant with T6 operating temperature class (85°C / 185°F)</li>
<li>Bolted directly to conveyor pulleys or return idler rollers via four 5/16″ holes</li>
</ul>
<h2>Technical Specifications</h2>

<li><strong>Operating Temperature:</strong> T6 class (85°C / 185°F)</li>
<li><strong>Ambient Temperature Range:</strong> −10°C to 55°C (14°F to 131°F)</li>
<li><strong>NEMA Enclosure Rating:</strong> 3S, 4, 4X</li>
<li><strong>IP Rating:</strong> IP65</li>
<li><strong>Mounting:</strong> Four 5/16″ diameter holes</li>
<li><strong>Rotation Direction:</strong> Bi-directional (clockwise and counterclockwise)</li>
<li><strong>Mounting Position:</strong> Any orientation</li>
</ul>
<h2>Typical Applications</h2>
<p>The CMS-1G is ideal for protecting critical conveyor system assets including:</p>
<ul>
<li>Belt conveyors and bucket elevators</li>
<li>Screw conveyors and rotary feeders</li>
<li>Pulley and return idler roller monitoring</li>
<li>Food processing, aggregate handling, and manufacturing plants</li>
<li>Ready-mix concrete production systems</li>
</ul>
<p>Output contacts can signal either machinery shutdown or alarm circuits to prevent compound damage from inoperative or failed conveyors.</p>
