Connector Pin Receptacles & Interconnects
Mill-Max Mfg. Corp. is the leading U.S. manufacturer of machined connector pins and receptacles. Our highly automated facility houses hundreds of production machines and a state-of-the-art plating department allowing us to ship in excess of 4 billion components annually. Mill-Max complements high speed-turning with a comprehensive selection of pre-tooled "multi-finger" spring contacts. Receptacles are made by press-fitting one of these contacts into a precision machined shell.
Our discrete connector line consists of:
PIN RECEPTACLES
Pin receptacles are individual component lead sockets primarily used for the plugging and unplugging of components on pc boards. Pin receptacles are made by press-fitting a pre-tooled "multi-finger" contact into a precision machined shell. These receptacles will accept round pins ranging in diameter from .008" to .102" as well as square & rectangular component leads and are available in several shapes and sizes.
WRAPOST (WIRE-WRAP) RECEPTACLES
Wrapost receptacles are individual component lead sockets with .025" or .045" square pin termination for wire wrapped interconnection. Wrapost receptacles will accept round pins ranging in diameter from .015" to .047" as well as square & rectangular component leads.
PRINTED CIRCUIT PINS
Printed circuit pins are machined, individual pins and are used for various plug-in applications and board to board interconnection. They are commonly fastened to pc boards by being press-fit, swaged or soldered.
WRAPOST (WIRE-WRAP) TERMINALS
Wrapost terminals are individual pins .025" or .045" square termination for wire wrapped interconnection. They are commonly fastened to pc boards by being press-fit, swaged or soldered.
SOLDER TERMINALS
Solder terminals are machined terminals used primarily for attaching wires to circuit boards. Turret, slotted and pin types are available. They are commonly swaged (riveted) and soldered to pc boards.
SPRING LOADED (POGO) PINS
Spring-Loaded Pins provide a reliable electrical connection in the most rigorous environments. Made of Precision-machined gold-plated components and a low-resistance spring maintain a consistent electrical path. Pins are tested to a minimum of 50G shock and 10G vibration with no spikes >1μs and >1.15V with 0.5A applied and are capable of 1,000,000 cycles.
APPLICATION SPECIFIC SOLUTIONS
Mill-Max's specialization in high-speed turning technology allows custom shells to be machined in a fraction of the time required by processes using swaging or stamping dies and at considerably less cost. A custom interconnect can be easily realized by selecting one of the 35 pre-tooled contact types and having it press-fit into a custom machined shell. The inner contacts (clips) are made from precision stamped beryllium copper and are designed in a multi-tine (or "multi-finger") style enabling them to accommodate round, square and rectangular component leads, and will accept pin diameters ranging from .008" to .102", encompassing most design applications.
