Inductive Proximity Sensor Detection Switch PNP DC5-36V 5mm Normally Close (NC)
The Inductive Proximity Sensor Detection Switch PNP DC5-36V 5mm Normally Close (NC) is a reliable and precise sensing device used to detect the presence of metallic objects without physical contact. Built for industrial automation, robotics, and embedded projects, it operates on the principle of electromagnetic induction to identify metal targets within a 5mm sensing range.
When a metallic object approaches the sensor’s detection face, it triggers an internal electronic switch that changes the output state — in this case, a PNP Normally Closed (NC) output. This means the output remains active (connected to +V) until a metal object is detected, causing the output to open (disconnect).
Thanks to its wide operating voltage (DC 5–36V) and robust construction, this proximity sensor ensures stable, high-speed, and noise-resistant performance, making it ideal for use in CNC machines, 3D printers, robotic arms, automated counters, and safety systems.
Integrate it easily with Arduino and Accessories or other microcontroller-based systems for real-time object detection and automation control.
