2M Ram-Lock Positive-Locking Push-Pull Interface
Amphenol’s Ram-Lock Push-Pull Interface Is Now Available in the 2M Family Of Products!
Featuring a positive locking Interface, the Ram-Lock is perfect for applications where accidental unmating is a concern. The user must pull on the operating sleeve of the plug to unmate, rather than the cable. Utilizing ball bearings for locking and a traditional D38999 EMI band for Shell-to-Shell conductivity, there is no need for problematic canted coil springs.
2MRAM Features • Push-pull with Positive-Lock • Visual, Tactile, & Audible Full-mate Indication • Prevents Accidental Unmating when Cable is Pulled • Full Environmental Sealing & EMI Protection • Lower Mate/Unmate Forces Compared to 2M804
Applications: • Soldier Worn Equipment • Electric Vehicle Recharging • Battery Terminal Connections • In-Line Power & Signal Connections
Important Note: Plug & Receptacle Terminology is Reversed Compared to 2M804, This is because the User Pulls on the Operating Sleeve to Disengage rather than the cable. For example 2M804-003 is known as a "Receptacle", 2M RAM-003 is a "Plug".
