Waterproof coaxial connectors

Meet Gradconn at Motiv8 RF and Wireless Design Forum

Motiv 8 RF & Wireless forumGradconn will be exhibiting our new  range of Nautilus connectors at the Motiv8 RF and Wireless Design forum on June 14th 2016 in Cambridge, UK.  Click on the above links to register for this event.

We’re looking forward to seeing you there to answer your questions and help solve your design problems. Our product range include a wide range of connectors for wireless solutions with a huge range of coaxial cable assemblies and SIM card connectors.

The Nautilus range of IP rated cable assemblies will be a particular focus for this event. We believe these will be of interest to Engineers working on designs in a wide range  of applications including Remote Sensing, Asset Tracking, Metering, Ag-Tech, Security and many others. Waterproof interface connectors mounted in an enclosure feature an internal seal and O-Ring which prevents ingress of water and particles through both the inner contact and the panel.

Board to board - bottom entry

Connectors demystified – Bottom entry board to board connectors

bottom entry board to board connectors

GradConn have created a guide to explain bottom entry board to board connectors, customers are often confused by the variety of board to board connectors female sockets on offer.

GradConn have forty five vertical PCB sockets with leaf spring contacts in the range.  Where sockets are described as dual or bottom entry they may accept header pins from underneath the PCB.  Customer must drill holes in the PCB to achieve this type of design, details of the required PCB cut-outs are shown on GradConn’s product drawings.  You can see an example in the ‘bottom entry socket’ image above.

Using a PCB socket in bottom entry mode allows customers to connect from the underside of the PCB,  this allows very low profile parallel PCB stacking solutions, which depending on pitch might be as low as 2.00mm to 3.00mm above the PCB.  It also allows designs which pass through the PCB to connect more then two printed circuit boards in parallel orientation.  You’ll find more information about that here.

Both surface mount and through hole connectors have bottom entry options.

That’s our guide to bottom entry board to board connectors finished.  We’ll be producing more of these guides in the weeks and months to come.  Please ask us if there any thing special you’d like us to cover.
