Description

The SN04-N2 inductive proximity sensor utilizes an electromagnetic field to detect the presence of ferrous and non-ferrous metal targets without physical contact. Its 2-wire DC normally open design simplifies installation by requiring only a power supply and load connection, with the output switching closed upon target detection.

Constructed for industrial durability, the sensor’s compact cylindrical body is engineered to withstand challenging environments common in automation, robotics, and manufacturing. The 4mm sensing diameter provides focused detection, minimizing interference from adjacent metallic objects and ensuring reliable performance in high-cycle applications.

Key Features

  • Non-contact inductive sensing principle for wear-free, long-life operation.
  • High switching frequency suitable for fast-paced production and counting applications.
  • Normally open (NO) output configuration compatible with standard PLC digital inputs.
  • Integrated 1.5-meter output cable for flexible installation and connection.
  • Durable housing designed for resistance to industrial contaminants like dust, oil, and moisture.
  • LED indicator provides immediate visual confirmation of sensor activation and output state.
  • Compact M12 or equivalent threaded barrel design for easy mounting in confined spaces.

Applications

  • Position sensing and end-of-travel detection on automated linear actuators and cylinders.
  • Object presence verification in assembly lines, packaging machinery, and conveyor systems.
  • Metal part counting and sorting in material handling and logistics automation.
  • Replacement for mechanical limit switches in high-cycle industrial machinery.
  • Safety interlock and door position monitoring in robotic work cells and enclosures.

Frequently Asked Questions

What is the wiring configuration for the SN04-N2's 2-wire DC output?

The SN04-N2 uses a 2-wire design where the same two wires carry both the power supply (6–36V DC) and the switched output signal. Connect one wire to DC+ and the other to your load (e.g., PLC input, relay coil). The sensor acts as a switch, closing the circuit (NO operation) when a metal target is within the 5mm detection range.

What types of metals can this inductive sensor detect?

The SN04-N2 can detect both ferrous (iron, steel) and non-ferrous (aluminum, copper, brass) metals. The actual sensing distance may vary slightly depending on the target material's conductivity and permeability, with steel typically providing the full 5mm nominal range.

What is the maximum current the sensor output can handle?

The sensor's output is rated for a maximum load current of 200mA. Ensure the connected device (PLC input module, relay, or indicator) draws less than this current. Exceeding 200mA may damage the internal switching transistor.

How do I interpret the status LED on the sensor?

The integrated red LED illuminates when the sensor's output is active (i.e., when a metal target is detected within range and the internal switch is closed). This provides immediate visual feedback for setup, troubleshooting, and operational monitoring.
