Description

The Panasonic CX-423 photoelectric sensor employs a diffuse reflective principle, where the emitted red LED light reflects off a target object back to the integrated receiver. This non-contact sensing method is ideal for detecting objects without requiring a separate reflector. The sensor’s built-in amplifier conditions the signal to provide a clean, switch-like NPN output for direct interface with PLCs, relays, or microcontroller digital inputs.

Engineered for industrial durability, the CX-423 features a robust housing with an IP67 ingress protection rating, making it resistant to dust ingress and capable of withstanding temporary immersion in water. Its wide -25°C to +55°C operating temperature range ensures stable performance in challenging environmental conditions common in factory automation, packaging, and material handling applications.

Key Features

  • High-precision diffuse reflective sensing with adjustable sensitivity
  • Industrial 12-24V DC wide-range voltage compatibility
  • NPN open-collector output for sinking current to common ground
  • IP67 protection against dust and temporary water immersion
  • Red LED indicator for easy status and alignment verification
  • Robust construction for reliable operation in harsh industrial environments

Frequently Asked Questions

What is the operating voltage range for the Panasonic CX-423 sensor?

The Panasonic CX-423 photoelectric sensor operates on a wide-range DC supply from 12V to 24V. This makes it compatible with standard industrial control voltages, ensuring easy integration into existing PLC and automation systems without requiring additional voltage regulation.

What type of output does the CX-423 provide and how do I wire it?

The CX-423 provides an NPN open-collector output. This is a sinking output, meaning the sensor's output pin acts as a switch to ground (0V). To use it, connect your load (e.g., a PLC input, relay coil) between the positive supply voltage and the sensor's output wire. The Brown wire is typically +V, Blue is 0V/GND, and Black is the NPN output signal.

Can the CX-423 sensor be used outdoors or in wet conditions?

Yes, the CX-423 is rated IP67, meaning it is dust-tight and can withstand temporary immersion in water up to 1 meter for 30 minutes. This makes it suitable for use in damp industrial environments, washdown areas, or outdoors where it is protected from direct, high-pressure water jets.

How do I adjust the sensing distance or sensitivity?

The sensing range of 70mm to 300mm is typically adjusted via a potentiometer located on the sensor body. Turning this potentiometer changes the receiver's sensitivity threshold, allowing you to fine-tune the detection point for different object colors, sizes, and surface reflectivities to prevent false triggers.
