Overview

The Dart Controls PU-2E (SKU: PU-2E) is a cost-effective, NPN-output speed sensor designed for indoor industrial applications. It features a Santoprene-molded head for dust and dirt resistance, a 6-foot UV-resistant cable, and supports shaft speeds up to 5000 RPM with a 1 pulse-per-revolution output. The sensor operates on 5 to 24 VDC and provides a sharp square wave output for tachometers, PLCs, SCADA systems, or counters. Installation is simplified via a single screw mount with a drilled and tapped target shaft. Ideal for motor not-running feedback in closed-loop control systems.
  • 1 pulse per revolution (PPR) output for precise speed monitoring
  • Operates on 5 to 24 VDC supply voltage with NPN output (sinks 50mA max)
  • Santoprene injection-molded head resists dust, dirt, and industrial contaminants
  • Supports shaft speeds up to 5000 RPM for high-performance applications
  • 6-foot UV-resistant cable included; extendable up to 300 feet
  • NEMA 12 rated for indoor industrial environments
  • Simple single-screw installation with drilled and tapped target shaft
