TE Connectivity (TE) has expanded its range of AMPMODU interconnection solutions with the introduction of 2mm centerline board connectors. These new connectors occupy 38% less space than traditional 2.54mm centerline products, while reliably and economically meeting the packaging and inter-connection requirements of today's miniature, sophisticated electronics. 

The products are designed for use across multiple industry segments where space constraints are of particular concern. Target applications include PLC and other I/O devices, servo drives, industrial automation and controls, industrial robotics, instrumentation and test equipment, and building and home automation devices. 

The new 2mm offerings will include breakaway headers and board-to-board receptacles, both supporting automated surface-mount, through-hole reflow (pin-in-paste), and traditional through-hole mount processes for ease of manufacturing.

The 2mm breakaway headers can be mounted onto boards with thicknesses of 1.6 and 2.4mm, providing customers with a wide range of options for PCB assembly. Through-hole headers feature straight or right-angle posts with a mating post length of 4.0mm and a lead length of 2.8mm and several other lead lengths, depending on board thickness and soldering method. 

They are molded in a flame retardant (UL94 V0) thermoplastic housing material that is resistant to reflow soldering temperatures and provides a high level of safety in harsh environments. The product offering includes single and double row variants and is available in bulk, tube, and tape and reel packaging offering flexibility in manufacturing. Shrouded headers are under development and will come to market in the near future.

The 2mm board-to-board receptacles are housed in a high-temperature-resistant liquid crystal polymer (LCP) and utilise phosphor bronze contacts with dual cantilever beams that are available in three gold plating thicknesses. The dual-beam design provides for increased contact surface between the header pin and the receptacle contact to allow reliable signal transfers. The complete portfolio includes various top- and dual-entry vertical and horizontal receptacles that offer multiple options for board-to-board stacking of header and receptacle combinations.

“We are excited to be able to grow our AMPMODU portfolio to now include a 2mm centerline offering that provides customers with a wide variety of rugged, reliable and versatile board connectors. This extension supports the trend in our industry of board miniaturisation while continuing to meet the high reliability and quality standards that our customers expect from TE,” said Sameer Trikha, Global Product Manager for TE’s Board Signal products.
