Rectangular Connectors - Headers, Receptacles, Female Sockets

The 861-83-035-10-001101 is a rectangular connector, specifically a socket header from the 860 family, which is designed to mate a surface mount card with a 3.5mm pitch, standardized on a 2mm height. It features a top-entry (“reverse”) style which is ideal for quick connect/disconnect conditions, with gold-plated contacts for optimal signal integrity. The standard 8.5 mm centerline distance between rows allows for easy remote mounting of the board and component.

Application Field

The 861-83-035-10-001101 socket header is designed for use in many industries. On the military and aerospace side, it can be used in mission-critical applications such as unmanned aircraft, satellite communication systems, and cryogenic payloads, using the industry-standard OS173 connector system from Ancor Aerospace. It can also be used for medical instrumentation, imaging equipment, and implantable medical devices, as well as communications and industrial equipment.

Working Principle

This socket header consists of eight-position row of alternating male and female contacts. The standard 2.54mm (0.1") pitch allows for a snug fit and excellent signal quality. The contacts are gold plated for superior conductivity and easy insertion. The solder tails feature solder-cup-style tails for improved solder retention to the board. The header is designed to mate with the OS173 connector system, which requires a 1mm gap for full engagement.

The 861-83-035-10-001101 features a top-entry (“reverse”) style design, which allows the contacts to be held in place using friction, rather than welding. This ensures a tight fit and reliable contact without any force required. There is also a high degree of shock and vibration resistance as the connection is secure and durable against movement.

This socket header is designed to be easily assembled and used. It can be installed on the board with thr use of solder paste or wave soldering. The socket header also provides excellent signal integrity due to its gold-plated contacts and 2.54mm pitch. The small size of the socket header also allows for it to be used in tight spaces.
