Description
Take your automation projects to the next level with the NJK-5002C Hall Effect Sensor, a reliable, non-contact magnetic switch ideal for detecting the presence of ferromagnetic objects. This NPN-type, normally open (NO) 3-wire sensor is perfect for use with Arduino, Raspberry Pi, or other microcontroller platforms, and operates in a wide voltage range of 4.5V to 30V DC, making it suitable for both low-power and industrial applications.
Whether you're designing a smart can crusher, door sensor, or automated counter, the NJK-5002C ensures consistent and accurate triggering in the presence of a magnetic field.
✅ Features:
NPN Normally Open (NO) Output
Activates output only when magnetic field is detected.Wide Operating Voltage (4.5V – 30V DC)
Flexible power compatibility for DIY and industrial applications.3-Wire Configuration (Brown: VCC, Blue: GND, Black: Output)
Simple wiring and easy integration with most microcontrollers.Non-Contact Magnetic Detection
Detects the presence of magnets without physical contact, increasing durability and lifespan.Built-in LED Indicator
Visual feedback when magnetic field is detected.Fast Response Time
Ideal for automation systems where quick sensing is critical.Rugged and Compact Design
Suitable for harsh environments or confined spaces.
Tips for Arduino Users:
Sensor Output is Active LOW when a magnet is nearby — even though it's labeled “NPN NO”, the output pin pulls LOW when active.
If you're using INPUT_PULLUP on the Arduino, the
digitalRead()
will return LOW when the sensor detects the magnet.Connect the Black wire to Arduino pin, Blue to GND, Brown to 5V (or 12V with appropriate voltage divider or optocoupler).
Always test the output using a multimeter or LED before connecting to the Arduino to verify behavior.
