Photoelectric Sensor Panasonic CX424 CX400 Series — Diffuse Reflex Light Sensor, 100 mm Range (CX424)

The Panasonic CX424 from the CX400 series is a compact photoelectric diffuse/reflex light sensor designed for short-range object detection. With a rated detection distance of 100 mm, the sensor detects the presence or absence of parts by measuring reflected light from target surfaces. The CX424 is intended for straightforward proximity sensing in industrial automation tasks where reliable short-range detection is required.

Advantages

The sensor offers a compact housing suitable for tight mounting spaces and a diffuse/reflex detection method that simplifies installation because no separate reflector or emitter-receiver alignment is required for many applications. The 100 mm detection range provides predictable sensing in assembly and conveyor contexts, while the robust Panasonic build supports continuous operation in industrial environments. The design focuses on simple integration with control systems and reliable detection of varied surface types within the specified range.

Suitable for

• Short-range object presence detection on assembly lines
• Part counting and gap detection on conveyor systems
• Basic proximity sensing for pick-and-place stations
• Quality control tasks requiring non-contact detection

Key specifications

• Detection principle: diffuse/reflex photoelectric sensing
• Rated detection distance: 100 mm
• Sensing target: reflective surfaces or objects within detection range
• Housing: compact form factor for constrained mounting spaces
• Typical applications: short-range automation and conveyor monitoring

How to use

Mount the CX424 so that the sensing face is aimed toward the expected position of the target objects at a distance up to 100 mm. Ensure the sensor cable or connector is compatible with your system wiring and follow the manufacturer’s wiring diagram for power and output connections. Adjust sensor position and, if applicable, sensitivity settings so targets reliably reflect sufficient light to be detected within the specified range. Test detection with representative parts and fine-tune orientation to minimise false triggers from nearby surfaces.

Usage recommendations

Place the sensor at a stable, vibration-free mounting point and avoid direct exposure to intense ambient light sources that may affect diffuse sensing. For targets with low reflectivity, reduce the distance or adjust angle to improve reflected signal. Regularly inspect the sensing face for dust or contamination and clean with a soft, dry cloth to maintain reliable performance.
