Tyco Electronics HD-20 Right Angle Plug Header

Category: Connectors, Electronics, Te Connectivity

Overview

The datasheet pertains to the HD-20 Right Angle Plug Header, Mark I+ developed by Tyco Electronics. This component is designed for secure electrical connections in various applications and features a range of specifications essential for its correct implementation and usage.

Material and Plating

The shell of the HD-20 Right Angle Plug Header is constructed from bright tin-plated steel. Grounding is ensured by 2×12 grounding springs with a pitch of 3.6 mm. For its housing, glass-filled polyester in black is used to provide robustness and durability. The contacts consist of phosphor bronze with specific plating capabilities and tin-plated steel for the internal thread (either 4-40 UNC or M3). Additional components such as the female screwlock, insert, bracket, and boardlock are made from tin-plated phosphor bronze or steel, which affords a consistent electrical connection. A post-alignment plate made from black glass-filled nylon is also included in the design.

Dimensions and Specifications

Key dimensions include a 3.1 mm diameter insert, alongside various other detailed measurements to ensure compatibility with corresponding parts and PCB layouts. The screwlock feature provides options for both 4-40 UNC and M3 internal threads. Accessories for the HD-20 are identified with a specific item number and their plating suffix, while the presence or absence of a groove on the connector indicates the version type.

Electrical and Mechanical Characteristics

The contacts are plated with gold over nickel as per performance level 2 (DIN 41652) and the solder part consists of 2.5um tin over nickel. The design ensures that air and creepage distances comply with DIN 41652 standards.

Coding and Identification

The datasheet specifies that cavity identification, the part number, and date code are on the front side only. Furthermore, an indicator groove designates the version with a 4-40 UNC inner thread; the absence of such a groove implies an M3 inner thread.

Additional Information

Datasheet revision details are outlined, including the amendment number (AMP 1471-9 REV 31MAR2000) and the drawing number. The documentation emphasizes that the dimensional specifics, unless stated otherwise, follow the specified PLC product, PLC application spec, angles, finish, and weight metrics, as per Tyco’s standard industry practices.

Drawing and Documentation

Important notes regarding the control status of the document are evident, reinforcing that this drawing is a controlled document that has been checked and approved by designated Tyco Electronics personnel. The datasheet is presented as a customer drawing with the size defined as not to scale (NTS), relating to the physical dimensions stipulated in the specifications.

Applications

While specific applications are not detailed within the first two pages of the datasheet, the design considerations such as grounding springs, robust materials, and compliant plating suggest suitability for a variety of electronic connection scenarios demanding reliability and adherence to industry standards.
