For high-reliability applications, Harwin has introduced the Datamate L-Tek, J-Tek and Mix-Tek connectors, which offer an improved accuracy of co-planarity in situations requiring horizontal or vertical board mounting.
The Datamate L-Tek and J-Tek horizontal, surface-mount connectors use a new contact system that guarantees co-planarity of mould and contact. These male connectors come in a range of mounting options, with the ability to withstand very high bending and shear forces. They are available with latches, jackscrews or jackscrew board mounts and can be used reliably with pick-and-place equipment.
Conventionally, horizontal board-mount connectors employ a straight pin which is bent twice to produce a horizontal contact. This method can make it difficult to maintain the accuracy of co-planarity (the degree to which the component sits square on the board). If bent incorrectly, the connector will not sit on the board properly, creating handling problems with pick-and-place equipment. Datamate L-Tek and J-Tek connectors eliminate this hazard by using a contact system which is pre-stamped, avoiding the need for bending.
The Datamate Mix-Tek connectors come in through-hole and surface-mount configurations and use the new contact system described above that guarantees co-planarity of mould and contact. Mix-Tek connectors combine signal, RF and power (10 to 20 A/contact) in the one small connector with a range of mounting options and are available with latches, jackscrews for board mounting, cable mounting or panel mounting.
Harwin's Datamate is a high-reliability connector system employing a four-finger beryllium-copper contact clip. It conforms with British Standard 9525-F0033 and can withstand high levels of shock and vibration in addition to a large number of mating cycles, all without loss of performance.
