Information About 42GDP-9004-QD8

The 42GDP-9004-QD8 belongs to the Allen-Bradley 42G General Purpose (GP) photoelectric sensor series, engineered for versatile detection tasks in industrial automation. This model is a standard diffuse sensor, which detects objects based on reflected light without requiring a separate reflector. It is powered by 90–264 VAC and includes diagnostic functions that simplify troubleshooting and system maintenance. The unit is designed with a quick-disconnect connection (QD8) for easy installation and replacement. With rugged construction, it is suited for demanding environments where reliable object detection is required. The 42GDP-9004-QD8 was discontinued by the manufacturer in 2016 but remains in use in legacy systems.

Key Features:

  • Series: Part of the Allen-Bradley 42G General Purpose photoelectric sensor family.
  • Sensor Type: Standard diffuse photoelectric sensor for general detection.
  • Power Supply: Operates on 90–264 VAC.
  • Diagnostics: Built-in diagnostic functions for monitoring and troubleshooting.
  • Output: AC/DC diagnostic output configuration (Type 4).
  • Connection: Quick-disconnect (QD8) design for easy wiring.
  • Operation: Detects targets using reflected light, no reflector required.
  • Application: Suitable for object detection and presence sensing in automation systems.
  • Durability: Rugged design for industrial use.
  • Status: Discontinued by manufacturer on September 19, 2016.

The 42GDP-9004-QD8 provides dependable photoelectric sensing performance and diagnostic capability for legacy automation systems.

Frequently Asked Questions about 42GDP-9004-QD8
Question: What is the Allen-Bradley 42GDP-9004-QD8 used for?
Date Update:27/05/2025
Answer:

The 42GDP-9004-QD8 is a diffuse diagnostic photosensor designed for object detection in industrial automation. It detects the presence or absence of objects by sensing the reflected light from a target surface. Its diagnostic capabilities allow it to monitor signal strength and operational status. This helps improve system reliability and supports predictive maintenance.

Question: Does the sensor require alignment or calibration?
Date Update:27/05/2025
Answer:

As a diffuse sensor, it does not require external reflectors, but correct alignment is still important for optimal performance. The sensitivity may need to be adjusted depending on object color, distance, and surface reflectivity. Diagnostic feedback simplifies setup by confirming when detection is stable. Factory calibration typically handles basic configuration.

Question: How is the sensor mounted?
Date Update:27/05/2025
Answer:

This sensor is typically mounted using standard sensor brackets or surface-mounting hardware. It should be positioned so the emitted light hits the target surface at a proper angle. Vibration and shock-resistant mounting is recommended to maintain alignment over time. It is compact and can fit into tight spaces on automation equipment.

Question: What is the electrical rating or voltage for this sensor?
Date Update:27/05/2025
Answer:

The electrical rating is not fully detailed in the summary, but sensors of this type commonly operate at 10–30V DC. Always consult the official datasheet to confirm voltage, current, and output type. The sensor typically has PNP or NPN outputs based on the model variant. It is designed for direct connection to PLC digital inputs.

Question: Is the Allen-Bradley 42GDP-9004-QD8 still being manufactured?
Date Update:27/05/2025
Answer:

No, the 42GDP-9004-QD8 has been officially discontinued since September 20, 2016, according to Rockwell Automation. There is no planned replacement in the RA product line. Customers are advised to remove references to this model in current designs and look for suitable alternatives from third-party providers or other RA sensor families.
