Technical Specifications to Verify

Verifying the contact material and insulation properties is essential for ensuring long-term reliability. Brass contacts are commonly observed, offering good conductivity, while PPS insulation provides thermal stability and chemical resistance. The contact resistance is a critical parameter, with some listings specifying values around 3.8mΩ, which impacts signal integrity and power loss. Buyers must confirm the contact type, whether solder or PCB mount, to ensure compatibility with their assembly process. The number of contacts, ranging from two to nineteen or more, must align with the circuit design to avoid unnecessary cost or performance gaps.

The IP68 rating indicates protection against dust and temporary immersion in water, but buyers should verify the specific test conditions and mating cycles. The latching mechanism, described as push-pull self-latching, must withstand the specified lifetime of 5000 mating cycles without degradation. Shell models, such as plug fixed sockets, and shell sizes like 0K, 1K, 2K, and 3K, define the physical interface. Key codes, including Key G or A, B, C, prevent misconnection in multi-connector systems. Buyers should also check the operating frequency, as some connectors are optimized for low frequency while others support high-frequency signals, ensuring the component meets the application's electrical demands.

Compliance and Safety Documentation

Compliance with international standards is crucial for global market access and safety assurance. While specific standards like IEC 61076-2-101 are mentioned in background knowledge, buyers must verify if the supplier provides test reports confirming adherence to these norms. RoHS certification is a key indicator of restricted hazardous substance compliance, which is mandatory in many regions. Buyers should request certificates of conformity and material safety data sheets to ensure that the connectors meet environmental regulations. The presence of ISOCE certification suggests adherence to quality management systems, but buyers should confirm the scope of the certification.

Safety documentation should also include information on the connector's performance under extreme conditions. Buyers should inquire about the results of environmental testing, such as temperature cycling and salt spray tests, which validate the IP68 rating. The warranty period, often linked to the mating cycle count, provides insight into the manufacturer's confidence in their product. Buyers should ensure that the supplier provides clear documentation on the connector's electrical ratings, including voltage and current limits. Proper documentation reduces the risk of non-compliance and ensures that the connectors can be safely integrated into the final product.

Cost Drivers and Commercial Terms

Several factors influence the cost of IP68 push pull circular connectors, including material composition, pin count, and certification status. Brass contacts and copper alloy housings are more expensive than alternative materials but offer superior performance.
