Military Latch/Ejector Header Overview

This datasheet provides detailed information on a 100″ x 100″ 3-wall Latch/Ejector Header that can be installed in either a straight or right-angle orientation and is designed to meet military specifications. It includes high-temperature options and a variety of features aimed at ensuring reliability and versatility in demanding applications. The header comes equipped with a 3M 3518 polarizing key, center bump polarization for correct mating, optional low-profile ejector latches, the provision of mounting holes for secure attachment to a printed circuit board, and a three-wall shroud for design flexibility. These headers also offer different tail options and the availability of optional polarizing posts. Customers can choose between rolled pin and snap-in latches according to their needs.

Physical Characteristics

The insulating material used in the header is a Glass Filled Polyester (PBT), with the option of a high-temperature variant using Glass Filled Polyester (PCT). Classified under the UL 94V-O flammability standard, this component comes in gray or beige color choices for the high-temp version. Each piece features the 3M logo, a part identification number, and an orientation triangle. The headers utilize copper alloy contact materials with various plating options. The underplate is made of nickel, while the plating on the wiping area is gold, and the solder tails are coated with a tin-lead alloy, with wrap tails having a gold flash finish.

Electrical and Environmental Specifications

From an electrical perspective, the header has a current rating of 1 A, insulation resistance greater than 1 x 10^9 Ω at 500 Vdc, and can withstand a voltage of 1000 Vrms at sea level, ensuring safe and reliable operation in electrical systems.
Environmentally, the header is robust, with a temperature rating from -55°C to +105°C, making it suitable for use in various climatic conditions. It is recognized under UL File No: E68080, indicative of its compliance with safety standards as set by Underwriters Laboratories.
