Miniature sealed connector system

A Bulgin Components product story
Edited by the Engineeringtalk editorial team Dec 5, 2000

Joining Bulgin's family of 'Buccaneer' sealed plastic connectors, the new 400 Series is the smallest in the range with an overall diameter of just over 19mm.

Joining Bulgin's family of 'Buccaneer' sealed plastic connectors, the new 400 Series is the smallest in the range with an overall diameter of just over 19mm, and, like its forefathers, offers environmental sealing to IP68.

Although small in size the 400 series is packed with specification.

Multiple pole connections, from two up to twelve way, have been chosen to offer the maximum number of configurations; the 2 and 3 pole are rated at 8A, 250V, the 4, 6 and 8 pole 5A, 125V and the 10 and 12 pole at 1A, 50V.

Using high quality gold plated crimp termination contact pins, contact resistance is less than 5m ohm and therefore suitable for mains power to signal applications.

Even within such a small connector, contact engagement is over 2.5mm to maintain electrical integrity.

The secure cable sealing system uses the tried and tested method offered by compressive collet, cable gland and retaining nut which can be found on far more costly metal connectors of this size but not other plastic versions.

Separate colour coded glands are available to provide sealing on cable diameters ranging from 3.5 to 7mm.

As well as sound sealing this design also produces exceptionally strong cable retention at over 80N.

Moulded in a tough flame retardant V-0 rated Nylon, the three body styles - flex, flex in-line and panel mounting - are each available with plug or socket contacts allowing cable to cable and cable to panel connection in either configuration, so, for example, an inlet and outlet connection with the same number of ways could be used on a single panel.

The connector faces are 'scoop proof' so any mis-mating will not damage the contacts and, in addition sealing caps are available to maintain the IP rating of unmated connectors.

Designed for applications where a cost effective, environmentally sealed connector solution is required and space is at a premium, the 400 series will give performance well beyond its diminutive size.
