Description

The Panasonic NA2-N20-PN is a sophisticated photoelectric area sensor engineered for reliable object detection across a wide area. It employs a through-beam sensing principle, where an array of 20 infrared LED emitters projects beams to a corresponding receiver. An object interrupting any beam triggers the PNP output, making it ideal for monitoring conveyor belts, entryways, or automated assembly lines.

Built for industrial environments, the sensor operates on a standard 12-24V DC supply common in control panels and features robust construction with an IP40 ingress protection rating. Its design ensures stable performance across a temperature range of -10°C to 60°C and humidity levels from 35% to 85% RH, providing dependable operation in demanding settings.

Key Features

  • Multi-beam through-beam detection for reliable area monitoring.
  • High 380mm detection height combined with a 5m sensing distance.
  • Infrared LED light source ensures stable operation unaffected by ambient light fluctuations.
  • PNP open collector output provides direct compatibility with PLCs and industrial controllers.
  • Integrated short-circuit and reverse polarity protection for enhanced system safety.
  • IP40 rated enclosure for protection against dust and limited moisture.
  • LED indicators for power, output status, and beam alignment diagnostics.
  • Optimized for detecting opaque objects with a diameter of 30mm or larger.

Applications

  • Conveyor belt object presence and counting systems in packaging and material handling.
  • Entry/exit monitoring and personnel detection for automated doors or safety light curtains.
  • Large-area object detection in automated storage and retrieval systems (AS/RS).
  • Machine guarding and intrusion detection on industrial machinery and robotic cells.
  • Package dimension verification and sorting on logistics and assembly lines.

Frequently Asked Questions

What is the output type of the NA2-N20-PN sensor and how do I connect it to a PLC?

The sensor features a PNP (sourcing) open collector transistor output. Connect the output wire to your PLC's digital input module. The PLC input common must be connected to the negative side of the sensor's power supply (0V) for proper operation, as the PNP output switches the positive voltage to the load.

What is the minimum object size this sensor can reliably detect?

The NA2-N20-PN is designed to detect opaque objects with a minimum diameter of 30 mm (φ30 mm). Smaller objects may not reliably interrupt the infrared beam, leading to missed detections. For consistent operation, ensure target objects meet or exceed this size specification.

What is the operating voltage range and power requirements?

The sensor operates on a 12-24V DC supply with a tolerance of ±10%. It is designed for standard industrial control voltages. Ensure your power source is within this range and can provide sufficient current, typically under 100mA, for stable operation and to activate the output load.

Can this sensor be used outdoors or in wet environments?

No. With an IP40 rating, the sensor is protected against solid objects larger than 1mm (like tool wires) but offers no protection against water ingress. It is suitable for indoor industrial environments free from dripping water, splashing, or condensation that could exceed its specified 35-85% RH operating humidity.
