MHF® I LK Locking Harness
I-PEX locking harnesses can support up to 9 GHz with a maximum mating height of 2.9 mm
The MHF I LK harness lineup from I-PEX improves upon the existing MHF I series by adding a robust mechanical lock to the harness to provide a secure and durable connection. The MHF I LK can support up to 9 GHz and has a compact profile with a maximum mating height of 2.9 mm. This enables use across a wide range of applications and industries where resistance to shock, vibration, and dependable RF signal integrity are paramount. The MHF I LK plug components are compatible with all versions of I-PEX MHF I receptacles, making it a versatile solution for a drop-in replacement on existing boards without design changes or inputting these solutions into new board designs.
