<h2>Overview</h2>
<p>The <strong>Lenord+Bauer GEL 2444TN1R 3K150-E</strong> is a MiniCODER incremental rotary encoder designed for precise speed and position measurement in industrial automation, motion control, and machine tool applications. This compact sensor module uses magnetoresistive sensing technology to contactlessly scan a precision target wheel, delivering direction of rotation, rotational speed, and position data without mechanical wear or maintenance.</p>
<h2>Key Features</h2>
<ul>
<li>Contactless measurement with magnetoresistive sensor technology—no bearing wear or maintenance required</li>
<li>Compact form factor (38 × 22 × 16 mm) for space-constrained installations</li>
<li>1 Vpp differential signal output (sin/cos or TTL/RS422 options available)</li>
<li>Frequency range 0–200 kHz with configurable interpolation for high pulse resolution</li>
<li>Extended operating temperature range: −40 °C to +120 °C</li>
<li>IP 68 rated housing with fully screened metal construction for EMI immunity</li>
</ul>
