Rear Mount SMA connector

Guide to rear mount SMA connector

Rear Mount SMA connectorCustomers often ask us about SMA mounting,  industry terminology can be confusing.  This guide to help you understand how to mount a rear mount SMA connector in a panel quickly and easily.

There’s often confusion about front and rear mount SMA connectors.   Rear mount means that the main body of the SMA connector, including the large nut is mounted inside the panel cut out, the washer and nut are screwed up outside of the panel. Rear mount SMA is the most common mounting method in the market place today.   See our front mount guide here.

GradConn offer rear mount SMA connector solutions in five options:

  • Straight SMA – Standard
  • Right Angle SMA
  • Straight RP SMA – Reverse Polarity with male centre pin
  • Nautilus waterproof straight SMA
  • Nautilus waterproof RP-SMA  – Reverse Polarity with male centre pin

Nautilus is a range of IP 67 & 68 rated connectors, find out more at our Nautilus web pages.

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.

Guide to Front mount SMA connectors

Guide to Front mount SMA connectors

We hope you find GradConns front mount SMA connectors mounting guide useful!  Customers often ask  about SMA mounting,  industry terminology can be confusions.  This is the first in series of guides to help you understand how to mount SMA connectors in a panel quickly and easily.

There’s often confusion about front and rear mount SMA connectors.   Front mount means that the main body of the SMA connector including the large nut is mounted at the front of the panel cut out, with the washer and nut screwed up from inside the panel.   This style is used to provide a tamper proof solution, as the connector cannot be unscrewed from outside the panel.  See our guide to rear mount connectors.

GradConn offer front mount SMA connector solutions in three options, standard SMA, Nautilus RP-SMA (reverse polarity) and  Nautilus SMA.   Nautilus is a range of IP 67 & 68 rated connectors, find out more at our Nautilus web pages.

Looking for a waterproof SMA jack connector?

Waterproof SMA connectors IP67 & IP68

Our customers often seek to prevent ingress of moisture and particles into SMA jack connectors.   The applications range from splash proof, up to fully submersed underwater.

Working hand in hand with customers, GradConn developed a waterproof SMA jack connector.   The Nautilus range of coaxial connectors offers IP67 & IP68 testing to 5 meters depth.  Testing also extends to particle ingress IP6x and pressure.

The image above shows the point of entry for water ingress when the connector is mounted in a panel.   The ‘problem’ section shows water ingress through the center contact and also thru the panel cutout.

The two ‘solution’ images show waterproofing of SMA connectors:

  • Rear mount SMA waterproof connector solution:
    • This is the most popular type of SMA, with the washer and nut screwing up on the outside of the panel.  The Nautilus solution contains both an external and internal O-Ring to prevent ingress.
  • Front mount SMA waterproof connector solution:
    • Using this type of connector allows the panel to be effectively tamper proof, as the washer and nut are tightened inside the panel.

A range of other Nautilus waterproof connector types are available, such as RP SMA, BNC, TNC and RP TNC. Front and rear mount options are available, an example of front mount and rear mount is shown in the image above.

Board to board connectors demystified – Polarized Connectors

Polarized connectors

Check out GradConn’s new pages, aimed at helping customers understand board to board connectors.

The first one deals with Polarization and shrouding on board to board connectors, it shows how polarized connectors work and provides useful links to GradConn’s parametric search.

Customers choose to use polarized connectors in applications where it’s important that the two mating connector halves are plugged together correctly, IE pin1 to pin1.

Connector polarization is achieved by a variety of methods, for larger pitch connectors, such as .100″ pitch contact spacing the normal arrangement is for the header with males pins to have a shroud, with a key cut into one wall, normally the longer side of the rectangle.  See example in the image above.  The mating socket has a raised bump, this ensures that the connectors may only mate in the correct orientation.

For finer pitches, such as .050″,  by definition are smaller and have thinner plastic sidewalls, extra keying features are built in.  For the PCB header, there’s a key on each shorter rectangular end, matched by a different sized pegs on each end of the mating PCB mounted socket.  In additional an off center top key provides extra polarization.

If you seek any further information or help with board to board polarized connector applications contact GradConn.

1.2mm pitch wire to board connector – Easy termination

1.2mm pitch wire to board connector

GradConn’s new 1.2mm pitch wire to board connector range offers mated height of 1.45mm above the PCB.  Its mating orientation makes it suitable for designs where space is at a premium.

Available in 2 – 6 positions, horizontal PCB headers are polarised to avoid mis-mating, housings and headers are plugged together from above, which is easier for operators and allows mating in applications where a traditional end-to-end mating may not fit.   Examples of applications are Solid state lighting, notebooks and GPS.

To prevent mismating, the housing polarising ‘rib’ allows mating with header only in the correct orientation. The mating connectors lock together with an audible click, which aids assembly.

Gold plated contacts are rated at 1.5A for mating headers and sockets terminated with 28AWG diameter cable .  WB06-DA has an operating temperature range of -25°C to 85°C and is packaged in tape and reel.

Cable assemblies are available to suit your design, including connector types from other manufacturers at the other end of the assembly.   Build  a custom cable assembly using the cable builder tool.
