Carlisle Interconnect Technologies (CarlisleIT) advances the design of the traditional push-on connectors with our new line of SMP-L connectors by adding a patent pending locking mechanism referred to as Secure-Lok™ to the standard SMP interface. Susceptibility to vibration and other environmental factors has historically limited designers to use threaded connectors such as the SMA, Type N, etc. Secure-Lok™ makes the SMP-L series of push-on connectors ideal for rugged military and commercial applications. SMP-L connectors and cables provide a strong retention force and are also available in sealed IP-67 compliant options.
