DOL Sensors DOL 43R Capacitive Sensor - 90-250VAC

The DOL 43 Capacitive Relay Sensor with Smooth Housing is a reliable solution for detecting feed, grain, and other solid materials in livestock and agricultural systems. Designed for flexible installation, the smooth (non-threaded) housing allows for easy mounting in a variety of applications, including use with glands, flanges, or custom setups in feeders, hoppers, and silos.

Built for performance in harsh environments, the DOL 43 features fully encapsulated electronics that protect against moisture, dust, and high-pressure cleaning. Its integrated 5A relay enables direct control of feeding and conveying processes, making it ideal for level detection, as well as managing filling and emptying operations.

The sensor includes adjustable delay-off functionality, allowing users to control how long the relay remains active after detection stops—helping improve system efficiency and reduce unnecessary cycling. LED indicators provide clear visual feedback, while NO/NC outputs and simple adjustment controls make setup quick and user-friendly.

Engineered for durability and long-term reliability, the DOL 43 is a low-maintenance, high-performance choice for modern livestock facilities.
