IP67 cable assemblies -The facts about connector design-are you fully protected
At GTT Wireless we pride ourselves in reliability and being able to substantiate our IP67 claims down to component level. So, let’s start with an explanation of IP67 connectors and the design criteria for true reliability.
Comprehensive consideration is essential for the following key factors to ensure robust IP-67 RF connector sealing:
- The O-ring
- The Panel D-Cut dimension
- The Panel thickness
- The Connector internal insulator seal contact against the connector body
- The Connector internal central-contact / central-pin seal contact against the insulator
The potential risk of water ingress when using a standard (non IP67) rated connector is significant when there is no protection from rain and humidity (where the connector integrates into the housing).

Look below the surface
Many lower-cost manufacturers try to simply eliminate this risk by fitting a rubber washer … this is unlikely to remain watertight for the long-term and especially in harsh outdoor conditions. Through professional IP67 reliability testing conditions these connectors will generally fail.
Sealing is the essence
At GTT Wireless, our connectors are specifically designed to accommodate the rubber washer ensuring it is uniformly compressed across the whole surface area giving total reliability in the field. Eliminating snagging or gripping seals is the key to long term reliability. Regardless of the connector type, N type, SMA, RPSMA or FME (and either front-lock or rear-lock design), we have an IP67 solution. All designed with reliability built in as demonstrated below.

Sealed to deliver absolute protection
GTT Wireless take this a final step further, for specific applications where there is a further need to provide a sealed external contact connector (where for example there are times when the external antenna is not connected to the connector in the field) … contact GTT Wireless to discuss these products further
