Overview

The Dart Controls PU-4R (SKU: PU-4R) is a rugged 2-pulse-per-revolution (PPR) speed sensor designed for reliable motor speed monitoring in harsh industrial environments. It features a NEMA 4 rating, making it suitable for outdoor use and washdown applications. The sensor operates within an ambient temperature range of -40°C to +100°C. Installation is simplified with a single-screw mounting design that requires no alignment. The encapsulated Santoprene head provides protection against dust, dirt, and moisture. A standard 6-foot UV-resistant cable is included, with the option to extend up to 300 feet. The PU-4R outputs a sharp square wave signal (5–24VDC supply) compatible with PLCs, SCADA systems, Dart tachometers, and closed-loop controls. It is ideal for applications requiring motor not-running feedback in industrial automation.
