5-555174-2 Modular Plug Assembly Datasheet

Category: Connectors, Electronics, Te Connectivity

Overview

The Tyco Electronics datasheet documents a Modular Plug Assembly, part number 5-555174-2. This component is designed for establishing electrical connections and is characterized by its precision-enforced dimensions, high-quality materials, and gold-plated contacts for reliable conductivity. It is a shielded, long body plug that accommodates stranded wires and is suitable for flat oval cable applications.

Materials and Construction

The datasheet specifies the use of durable materials in the construction of the modular plug assembly. The housing is made from clear polycarbonate, providing a robust shell for the internal connections. Electrical contacts are fabricated from 0.36[.014] thick phosphor bronze, ensuring good electrical conductivity and resistance to corrosion. These contacts are finished with:

1.27 μm [.000050″] thick gold plating in the localized gold plate area.
A gold flash over the remainder of the contact surface.
2.54 μm [.000100″] thick nickel underplate beneath the gold layers for additional corrosion resistance and durability.

The external metallic shield is constructed from 0.25[.010] thick copper alloy with a satin nickel finish, potentially serving both as a physical protection for the wiring as well as a means to reduce electromagnetic interference.

Dimensions and Design

The datasheet emphasizes the precision of the plug’s dimensions, pointing out that all measurements provided are maximums unless specified otherwise. Specifics include the plug accommodating a wire diameter of 0.74-0.99[.029-.039] with 26 or 28 American Wire Gauge (AWG), underlining the plug’s compatibility with standard wire sizes for telecommunications and data applications.

Crucial for the function of the plug is the latch which, post-crimping, should remain in the detailed position to ensure secure attachment to the counterpart socket. The maximum terminated dimension allowed is specified to be 6.15[.242].

Packaging and Compliance

Each package contains 500 assemblies, streamlining the supply process for bulk users. In accordance with contemporary environmental standards and regulations, the plug assembly is marked as lead-free, making it suitable for use in various international markets that demand adherence to strict hazardous substance regulations.

Documentation and Quality Control

The datasheet itself is marked as a controlled document, referencing a specific ECO (Engineering Change Order) -08-020668 and dated the 27th of August 2008. The release of such detailed information underscores Tyco Electronics’ commitment to transparency and quality.

The plug assembly has been approved and specified on the drawing as per company protocol, with Gene Reed being noted as the responsible individual. The document is drawn to scale and provides a detailed “A” section, highlighting the after-crimping latch position at a scale of 10:1, emphasizing the precision and attention to minute details typical for modular plug assemblies.
