The 281739-5 is a popular rectangular connector header from Amphenol with a 2.00mm pitch and a maximum current rating of 2.5 Amps. The header is typically made from a thermoplastic material with tin-plated copper alloy sleeves and uses standard surface mount technology for reliable and secure mounting. It is designed to meet the requirements of demanding and high-density applications in the telecommunications, consumer electronics, automotive, and medical industries.

It features a two-piece, zero-insertion-force design that provides superior holding power and reduced installation time. The header contains four rows of four-pin terminals arranged in vertical and horizontal directions. Its male pins are made of phosphor bronze, have a gold plating, and a 0.5mm dia. The header’s construction uses a combination of thermoplastic and metal shells, together with retention features that provide secure connections.

The 281739-5 is ideal for applications that require reliability and high durability. It has a very low profile, making it well suited for space-constrained assemblies. It offers high packing density and is available in multiple rows, allowing it to accommodate larger numbers of contacts. The pin contacts are easily pushed into the header’s receptacles, providing a secure connection with the target board. The connector is also designed to ensure that the contacts are picked up from the PCB reliably and accurately when removed.

The 281739-5 offers a number of useful features designed to help make the connection process faster and more reliable. These include quick-release hardware, cable retention features, and an anti-vibration clip. It also allows for quick connector mating and un-mating with the use of a threaded mating locknut. In addition, the header has wire guards that provide excellent protection against accidental or intentional shorting.

The 281739-5 is a durable and reliable rectangular connector header with excellent mechanical and electrical performance. It is specifically designed for applications in the telecommunications, consumer electronics, automotive, and medical industries. It features a low profile, high packing density, and quick connector mating and un-mating.
