New Original Autonics PR12-4DN PR Series Cylindrical Inductive Proximity Sensor<\/h1>\n<\/div>\n
\n

1. Product Overview<\/h2>\n<\/div>\n
\n
The Autonics PR12-4DN belongs to the PR series cylindrical inductive proximity sensor. It adopts shielded M12 nickel-plated brass threaded housing with a rated sensing distance of 4 mm. This unit is a 3-wire DC NPN normally open inductive sensor with built-in reverse polarity protection and short-circuit protection. It realizes non-contact detection of ferromagnetic metal objects and converts proximity signals into digital switching signals. Widely used for workpiece detection, position feedback, counting and travel limit control on automated assembly lines, machine tools, conveyor systems and packaging machinery. The supplied unit is brand new original genuine Autonics product.<\/div>\n<\/div>\n

3. Main Functions<\/h2>\n<\/div>\n
\n
    \n
  1. Detect ferromagnetic metal targets without physical contact to avoid mechanical friction, collision and wear.<\/li>\n
  2. Output NPN digital switching signals to trigger PLC input modules, relays and other control components.<\/li>\n
  3. Red LED status indicator facilitates on-site inspection and rapid fault diagnosis during commissioning.<\/li>\n
  4. Achieve position confirmation, workpiece counting and travel limit protection for automatic production equipment.<\/li>\n
  5. Support continuous high-frequency repeated switching to meet long-cycle operation requirements of automation machinery.<\/li>\n
  6. Shielded structure allows flush embedded installation to prevent mechanical impact damage on the sensing face.<\/li>\n
  7. Provide reliable detection signals for equipment safety interlock and automatic process logic control.<\/li>\n<\/ol>\n<\/div>\n
    \n

    4. Technical Features<\/h2>\n<\/div>\n
    \n
      \n
    • Standard M12 threaded metal housing, matched with lock nuts for convenient installation and position adjustment.<\/li>\n
    • Shielded design supports flush mounting without reducing the rated sensing distance.<\/li>\n
    • IP67 sealing structure effectively resists dust, splash water and oil mist in industrial workshops.<\/li>\n
    • Complete built-in circuit protection prevents sensor damage caused by miswiring and load short circuit.<\/li>\n
    • Excellent anti-electromagnetic interference performance for stable operation under complex industrial electromagnetic environments.<\/li>\n
    • High repeat accuracy of sensing distance to maintain consistent detection performance during long-time operation.<\/li>\n
    • Compact cylindrical structure, suitable for installation in limited mechanical spaces.<\/li>\n
    • Wide operating temperature range, adaptable to variable-temperature factory environments.<\/li>\n
    • Stable output characteristics under fluctuating load conditions.<\/li>\n
    • Good vibration resistance to adapt to continuous running industrial equipment.<\/li>\n<\/ul>\n<\/div>\n
