Overview
This datasheet details the specifications for the Header Assembly, a single row Printed Circuit Board (PCB) connector manufactured by Tyco Electronics Corporation. The document includes a variety of part numbers associated with different configurations of the connector, which may be broken to the desired number of positions to accommodate various applications.
Construction and Design
The connector is characterized by its 0.51[.02] or 0.025 square post and is unshrouded. The housing is made from a black, flame-retardant thermoplastic. Critical dimensions and tolerances are outlined, ensuring compatibility with PCB designs and secure fitting during assembly. A key feature of this component is the true position tolerance of the post tips, which is essential when the header is held flat against the PCB.
Part Numbers and Dimensions
Each part within this series has a unique identifier, depicted as varying series of numerical sequences formatted as 1-146477-x, where ‘x’ varies to indicate the specific part number. The document details the number of positions available for each part, from 6 to 40 positions, along with precise measurements for each dimension, ranging from the length and width of posts to spacing between them. For instance, dimensions such as 2.54[.100] for spaces and 27.94+0.25 [1.100+.010] for specific lengths are noted.
Finishing and Compliance
Important to the functionality and durability of the Header Assembly are its finish options—bright tin-lead and matte tin, both over nickel plating, ensuring proper conductivity and resistance to corrosion. The exact thickness of the plating is carefully controlled and specified within the datasheet.
Additional Information
The datasheet specifies that this is a controlled document, revised as of March 31st, and it includes reference to the individual responsible for its approval. This suggests an emphasis on quality control and conformity to internal and potentially external standards.
Instructions for Use
For appropriate assembly, a recommended hole layout is prescribed, indicating the exact measurements for drill holes on a PCB to fit the connector. The dimensions apply specifically at the intersection of the post and the housing to maintain consistency and reliability.
Important Notices
The datasheet explicitly highlights the reserved rights and publication standard of Tyco Electronics Corporation, implying proprietary information and restrictions on the circulation of the document.
