WS Series Aviation Connectors Types, Materials, and Specs

Selecting the Right Connector for Combine Harvester Grain Flow Sensors

When choosing a connector for the grain flow sensor in a combine harvester, the primary decision hinges on environmental resilience, signal integrity, and mechanical durability. The M12 series (IP67) is a recommended solution for this demanding application.

Key Selection Criteria for Harvester Sensor Connectors

• Signal Transmission: A 3-pin configuration is sufficient for transmitting flow signals with an accuracy of ±0.1 kg/s.
• Environmental Protection: The IP67 rating ensures protection against dust ingress and temporary water immersion, which is critical in dusty field conditions.
• Mechanical Strength: The PA66 + glass fiber shell provides impact resistance to withstand grain impact and vibration up to 15g.
• Corrosion Resistance: Nickel-plated contacts offer resistance to grain dust and pesticide corrosion, extending the connector's service life.
• Maintenance Cycle: With a plug-in life of ≥5000 cycles, the connector supports maintenance during the annual idle period.

Application Fit and Performance Notes

This connector is specifically suited for the vibration and dusty environment of a combine harvester. The material and plating choices are directly aligned with the operational demands of agricultural machinery, ensuring reliable performance throughout the harvesting season.

Selection Advice for Your Harvester Setup

When integrating this connector, verify that the mating cable assembly matches the 3-pin layout and IP67 rating. For applications with similar environmental demands, consider reviewing other agricultural machinery connector solutions to ensure compatibility with your specific sensor interface.
