The UK’s prime source for PCB and backplane, dsub, rectangular and multiway circular connectors; cable assemblies and wire harnesses.

In2Connect UK Ltd the UK based specialist supplier of waterproof connectors, has added Hermetic Glass to Metal M12 connectors to its already extensive IP rated waterproof range. These glass to metal hermetically sealed IP68 M12 male socket connectors are designed to exceed the mechanical and environmental requirements of IEC-61076-2-101 with fixed pin contacts, fused into a glass dielectric insert. Hermetically sealed M12 connectors from In2Connect are available as receptacles with eyelet, solder bucket and/or PCB contacts.

Based on the M12 threaded connector range, the new connectors have been designed and manufactured to meet customers’ stringent individual requirements for environmental, mechanical and mounting conditions. Hermetic M12 connectors from In2Connect are designed to exceed IP68 in an unmated state. These connectors have a wide variety of applications and can be found in most industry sectors, such as transport and instrumentation, for use with proximity switches, sensors and interconnection in harsh environmental conditions. Standard Hermetic connectors are sealed by fusing a single piece glass insert into a machined Stainless Steel Shell. The pin contacts are permanently fused into the insert. To maintain thermal compatibility with the glass insert, the contacts are manufactured from a nickel alloy. The protective plating on the pin contacts is electro-deposited gold over nickel.

The Jam Nut is supplied with a fluorosilicone rubber O-ring for panel sealing. All M12 connectors and M12 hermetic connectors are RoHS compliant. The standard hermetic M12 connector is not designed as a pressure resistant connector even though the inserts are capable of withstanding high pressure differentials.

  • Installation size – M12 X 1
  • No of contacts – 3, 4, 5, and 8
  • Compact, Robust design
  • Hermetically sealed in stainless steel shell.
  • Hermeticity – Leakage of less than 1 x 10-8 cc/sec at one atmosphere pressure differential
  • Corrosion resistant
  • Coding – For non-standard coding please consult


In2Connect offer a full range of IP67/69 rated environmentally sealed circular connectors and pushbutton switches designed to provide secure and safe connections in harsh or hostile conditions.

In2Connect are an outlet for Souriau UTS High Seal connectors which are plastic bodied bayonet connectors, compatible with MIL-C 26482 circulars and Conxall MIL-E-QUAL plastic bodied equivalents to MIL-C 5015 circular connectors.

In2Connect also offer an extensive range of waterproof dsub connectors in standard, high density, combination and filtered designs. Socket and plug connectors are available with solder cup, straight or right angled PCB contacts. 

Designed with a one-piece Solid Body zinc die cast housing to resist mechanical impacts during installation and operation and minimise possible leakage paths; these connectors comply to current solder requirements with RoHS compliant solder temperatures. These types are both UL and CSA approved. With this water resistant d-sub system, the back-potted and ‘O’ ring mounted panel connectors always ensure full IP67 conformity whether mated or unmated and can be further protected by an end cap when unmated. The mating cable end connector can have a waterproof hood as shown in the colour picture above. This has a compression ring to stop the ingress of water via the cable entry point at the rear and a sealing skirt at the connector interface. The cable-end connection will not itself meet IP67 when unmated unless a waterproof cap is fitted. Once mated, then the total connection interface, not just the panel mount connector will conform to IP67.


From a data signal viewpoint In2Connect also specialise in waterproof industrial versions of the RJ45 and USB connectors. The Ethernet RJ45 meets Cat 5e requirements for data rates up to 100Mbs, whilst the USB is designed to meet USB version 2.0 specifications for data rates up to 480Mbs.


To complete the waterproof family, Optical fibre LC connections with IP68 ratings are now also available enabling much simpler and quicker connections for applications where standard fibre cabling would not stand the strain; whilst ITW Switches offer an exhaustive range of fully sealed panel, pushbutton switches to IP67.


In2Connect UK Ltd is a manufacturer as well as franchised distributor for many of the industry”s leading electronic connector manufacturers including In2Connect, ITW McMurdo, ITW Switches, Conec, ept, Sullins, Nicomatic, Essen, HTP, EDAC, Kukdong, Nicomatic, Sunkye and Calmont Wire and Cable.
