Two-piece connector system carries up to 5 A

-December 13, 2013

Engineered for board-to-board and board-to-wire interfaces, the DF64 series of horizontally mated two-piece connector systems from Hirose handles up to 5 A, depending on the wire gauge, and provides a voltage rating of 350 V AC/DC. They feature a common receptacle that mates with the header and the cable plug. The 4.5-mm–pitch connector system has dimensions of 20.4×14.4 mm and a mated height of just 4.7 mm.

A stress-free floating-contact structure absorbs movement and misalignment between PCBs, allowing the connectors to compensate for manufacturing tolerances and thermal expansion. Movement tolerance range in the X axis is ±0.5 mm; movement tolerance range in the Y axis is 2 mm maximum. Additionally, a creepage distance of no less than 3.2 mm helps prevent arcing.

The DF64 devices are capable of operating at temperatures of up to 105°C. Connectors are UL-recognized, RoHS-compliant, and halogen-free. Typical applications for the DF64 series include LED lighting, medical devices, copiers, factory-automation controllers, and general board-to-wire connections.
