Amphenol Industrial Floating Mate Connectors

Amphenol Industrial Floating Mate Connectors combine power and signal in one interface for drawer-style battery modules and power shelves. Amphenol Industrial Floating Mate Connectors are built around RADSOK power contacts and support up to 120A per power contact and 1000VDC to 1500VDC (variant-dependent). Integral guide pins and optional floating mount hardware improve blind-mate alignment and reduce mating stress during serviceable module swaps. The Floating Mate Connector series is offered in 2+12, 4+12, and 4+12 Mini configurations. First-mate/last-break positions are available for grounding or interlock-style functions. Touch-safe IP2XB power contacts and compliance to UL 4128, TÜV 2PfG2740, and IEC 61984 (UL 94 V-0 insulators) support safe, standards-driven designs.

Application Note

Battery-based energy storage and electrified platforms are pushing toward higher power density, tighter packaging, and serviceable, modular architectures. As systems move to drawer-style battery modules and power shelves, designers need an interface that supports blind mating, reduces assembly complexity, and maintains reliable electrical performance over repeated service cycles.
