Radiall has expanded its range of SMP products with SMP-LOCK connectors featuring a robust locking mechanism which increases the retention force of the interface and prevents accidental disconnection.
Offered with a limited number of receptacles and straight or right-angle plugs for standard cables, the new connectors can be customised to fit preferred cable types or to meet the needs of specific microwave modules. They have been specially designed for harsh environments and to withstand severe vibration and drop tests.
SMP-LOCK connectors are suitable for cable-to-cable or cable-to-module interconnections inside equipment subject to harsh mechanical stress such as airborne radars, avionics, satellites, missile, and UAV and UGV applications. For high-density PCB or panel layouts, an extraction tool is available to ease the connect/disconnect operations. SMP-LOCK plugs are compatible with most standard SMP receptacles in the unlocked position, with the exception of ‘catcher’s mitt’ type.
The addition of an innovative locking mechanism to the SMP interface makes it less vulnerable to the most demanding vibration and shock requirements. With this system, the retention force of the connector when locked is specified at 450 N with 0,085” semi-rigid cable. This level of retention is 10 times more than with standard SMP full detent interface.
The actual force required to break apart male and female connectors when locked has been measured at 1500 N, which is claimed to be the highest in the industry for this type of micro-miniature connector.
