Exceed high-current and reliability requirements in top-
end server and high-power applications with Molex’s
compact, EXTreme Guardian™ Power Connector System,
providing EMI/RFI shielding, overmolding and discrete-
wire options for design flexibility
EXTreme Guardian™ header and cable assemblies, previously named EXTreme
Power™ Interconnect (EPIC), feature small package sizes with a centerline
pitch of 11.00mm. The system supports up to 80.0A per contact, provides
good shielding characteristics in EMI-sensitive environments, features hot-
plugging capabilities and UL safety features.
Headers are available in 2-circuit, single-flanged and 3-circuit, dual-flanged
versions. Cable assemblies are available in 3-circuit, straight, shielded and
unshielded versions for high-voltage applications and are UL touch-safe.
Additionally, the 2-circuit cabled solutions include a straight, unshielded cable
assembly; a right-angled, right-entry and left-entry unshielded version, as
well as a left-entry shielded variant for space-saving connections to servers
installed in confined spaces.
