Cliff XLR Shell LC Duplex & SC Simplex Feedthrough Adaptors - Plastic Shell - Cliff CP30215, An SC Simplex SM connector mounted in a plastic XLR format body shell with countersunk mounting holes - part of the FT Series from Cliff\'.Cliff\'s FT Series of feed through connectors is perfect for custom I/O configurations on wall-plates, rack panels, etc., because all of the connectors in the series are housed in a standard XLR shell and fit into a standard XLR panel cutout. Standard cables are used for external and internal connections, so no soldering or punching is necessary, just use the standard cable for that particular connector style. The connectors can be mounted from either the front or the back of the panel and their low rear profile can accommodate the tightest \'behind the panel\' spaces.
