L-com's ECF style High Retention USB adapters provide an easy to use mountable USB solution featuring a high retention connector that provides 50% (minimum) greater connector retention than standard USB connectors. This feature is ideal for applications where mated cables can become detached by jostling, vibration, etc. These adapters are available in B-A, A-A, and A-B connector configurations, and all three feature a shielded housing. L-com's 4-40 screws (PN# ECF440) are used to mount these adapters and are sold separately.
