BMQC couplings

- Spill-free Blind-Mate Quick Connector
- Extra high ±5 mm radial misalignment tolerance
- Compact design for data center liquid cooling
CEJN OCP BMQC (Blind-Mate Quick Connector) is a coupling solution developed for Direct Liquid Cooling (DLC) applications in data centers. BMQC was developed within the Open Compute Project (OCP) initiative, with CEJN supporting the development and testing of the product.
The Blind-Mate functionality enables connection even when the mating components are not perfectly aligned. BMQC has a radial misalignment tolerance of ±5 mm and an angular misalignment tolerance of ±2.7°. Its spill-free and compact design makes it particularly suitable for data center liquid cooling systems.
Applications: Direct Liquid Cooling (DLC) systems in data centers.
