Overview of A1 and A2 Series 2.54mm Pitch High Density Connectors
The 2.54mm Pitch High Density Connector A1 and A2 Series comprise high-density mounting connectors designed for longitudinal alignment on a 2.54 mm mesh board to maximize space utilization. The A1 series offers 16 variations with 6 to 64 contacts, and the A2 series presents 20 variations ranging up to 20 contacts, enhancing design flexibility for various applications. These connectors are built to be compatible with the HIF3B series cable side and HIF3H receptacle, ensuring wide applications across different electronic devices.
Product Specifications
The connectors are rated for a current of 3A and an operating temperature range of -55 to +85°C. They can withstand voltages up to 200V AC and can operate within moisture ranges of 40 to 80%, accommodating different environmental conditions. Further reliability is demonstrated by an insulation resistance of 1000M ohms minimum and a contact resistance capped at 15m ohms. Testing protocols include enduring vibrations with no electrical discontinuity of 1µs or more and maintaining insulation resistance after steady-state humidity conditions. They are also tested for durability through temperature cycles and resistance to soldering heat without performance loss.
Material Composition
Materials used in the construction of the segments of the connectors include PBT, brass, and polyamide for the insulator pin header, contact crimping socket, and crimping contact respectively. Components feature a selective gold-plated finish and compliance with UL94V-0, attesting to the quality standards and flammability criteria they meet. The connectors are available in both black and selective gold plated finishes.
Applications and Ordering Information
These connectors are essential in connecting electronic components within computers, VTRs, and a wide array of electronic equipment. Ordering codes for the product series are provided, detailing the series name, number of contacts, contact pitch, and type. Additionally, information is furnished for crimping sockets and contacts, such as series number, contact alignment, connection type, applicable cable size, and packaging type.
