Technical Specifications Explained

Understanding the technical specifications of the 491-B is essential for proper component selection and optimal system performance. Manufacturing tolerances are held to industry standards, ensuring dimensional consistency across production batches. This precision is critical for reliable mechanical performance and preventing assembly issues during installation. When specifying this component, design engineers should consider operating temperature range, environmental conditions (humidity, chemical exposure), mechanical loading (static vs. dynamic), and installation requirements. Proper specification ensures long-term reliability and minimizes field failures in deployed systems.

Integration Guidelines & Best Practices

Successful integration of the 491-B requires careful attention to design best practices and installation procedures. Follow manufacturer installation guidelines carefully, paying attention to specified torques, clearances, and environmental requirements. Verify that all mating components are compatible and that assembly sequence prevents damage to the component or surrounding systems. Common integration challenges include proper component alignment, adequate fastening torque, and environmental protection. Address these proactively during design phase to minimize field issues. After installation, perform functional testing to verify mechanical integrity, proper fit, and absence of stress concentrations. Documentation should include torque values applied, thread engagement verification, and any deviations from standard installation procedures. This traceability is essential for aerospace and defense applications requiring full installation records.

Industry Standards & Compliance

The 491-B meets comprehensive regulatory and industry standards requirements to ensure compliance for global markets and regulated industries. RoHS (Restriction of Hazardous Substances) compliance ensures this component is manufactured without lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), or polybrominated diphenyl ethers (PBDE). This compliance is mandatory for electronic equipment sold in the European Union and increasingly required in other global markets. RoHS certification reduces environmental impact and ensures regulatory compliance for your finished products. Industry compliance includes adherence to MIL-STD (Military Standard) specifications for defense applications, IPC/JEDEC standards for electronics manufacturing, and ISO 9001:2015 quality management systems certification for consistent manufacturing processes. For aerospace applications, AS9120B certification ensures proper handling, storage, and traceability of aviation components throughout the supply chain. Certificates of Conformance (C of C) documenting compliance with manufacturer specifications are available for all shipments. For aerospace, defense, and medical applications requiring enhanced traceability, full material certifications and test reports can be provided. Contact our quality assurance team to discuss specific documentation requirements for your application. REACH (Registration, Evaluation, Authorization, and Restriction of Chemicals) compliance ensures this component meets European Union chemical safety regulations. This regulation restricts Substances of Very High Concern (SVHC) and ensures chemical safety throughout the product lifecycle. REACH compliance is essential for products distributed in EU markets and increasingly referenced in global supply chains.
