New Original Keyence PR\u2011M51N3 Thrubeam Photoelectric Sensor<\/h1>\n

Product Overview<\/h2>\n

This original new mini slim thrubeam photoelectric sensor belongs to Keyence PR\u2011M series. It consists of transmitter and receiver units with integrated amplifier. It detects workpiece presence when objects block the red light beam. The compact metal housing suits limited installation space for part counting and object detection in automated assembly and packaging equipment.<\/p>\n

Main Functions<\/h2>\n
    \n
  1. Realize object detection by interruption of infrared red light beam<\/li>\n
  2. Provide dual NPN open collector outputs with Light\u2011ON and Dark\u2011ON mode<\/li>\n
  3. Equip multi color LED indicators to show power supply and detection status<\/li>\n
  4. Suppress interference from surrounding ambient light for stable operation<\/li>\n
  5. Complete high speed detection for moving small parts on production lines<\/li>\n<\/ol>\n

    Technical Features<\/h2>\n
      \n
    • Four element point red LED light source at 650 nm wavelength<\/li>\n
    • SUS316L stainless steel housing for splash and dust resistance<\/li>\n
    • Built\u2011in protection against reverse power connection and output over current<\/li>\n
    • Fast response time adapts high speed cyclic detection<\/li>\n
    • 3 meter long fixed cable for flexible field wiring layout<\/li>\n<\/ul>\n
