EXTreme Guardian Power Connector System

Molex has announced the addition of 2, 3, 4, 5, and 6 circuit harness connector components to its EXTreme Guardian Power Connector system. The new components include non-overmoulded latching cable receptacle housings, terminal position assurance clips (TPAs) and latchable vertical and right angle headers providing power supply manufactures with more options when designing for the high current density needs in the computing and telecommunication markets. The EXTreme Guardian system delivers power of 80.0A per blade (185.0A per inch) in a small form factor while providing electromagnetic interference (EMI) and radio frequency interference (RFI) shielding options.

“Accelerating computing demands are putting pressure on manufacturers to deliver greater power capabilities. At the same time, requirements for reliable, redundant power force associated subassemblies to take up less physical space,” said Jeff Torres, global product manager, Molex. “The EXTreme Guardian solution was designed to meet these challenges by delivering the high-power requirements for today’s networking and datacom equipment while offering a small centerline spacing of 11.00mm, greatly reducing the PCB footprint when compared to legacy power products.”

The EXTreme Guardian solution is UL and CSA certified and capable of handling up to 600V, supporting high voltage with the lowest feasible voltage drop and I2R (irreversible dissipative power) losses. It has recessed terminals and features first-mate/last-break (FMLB) capability to allow hot-swapping of power units for reduced network downtime. The PCB headers use locating pegs that allow accurate through-hole positioning of the connector on the board and are available in through-hole solder and press-fit for additional manufacturing options. The harness crimp terminals accept 10, 8, 12/12 or 6A WG wire and can minimise terminal back out issues with a terminal position assurance (TPA) option while an integral latch secures the cable from accidental disconnection.
