Industrial Ethernet connector links field devices

Tyco Electronics recently introduced a complete offering of sealed RJ45 industrial Ethernet connectors and cable assemblies. The connectors and cables are designed for many demanding manufacturing, processing and commercial applications.
The connectors combine an industry proven mini-form circular housing with an RJ45 receptacle. The receptacles are available in a variety of configurations to match many application requirements. A 110 punchdown block is available for quick, easy insulation displacement connections (IDC). This receptacle style is suitable for many premises wiring applications. Additionally, another receptacle style is available for PCB installation. This style is a short depth version intended for OEM designs that require an IP67 rated, robust connection for field equipment. A standard PCB receptacle is also available which allows a designer to solder a cable lead to an industrial Ethernet connection. Lastly, a bulkhead passthrough receptacle is available. This version allows designers to bring Ethernet to a control box and creates a sealed interface rated for IP67.
The connectors are moulded from ABS for the standard version with additional materials available for outdoor applications requiring UV stabilisation. The RJ45 jack contacts are copper with nickel underplating and gold finish. Mating cycles are rated at up to 250. Electrical performance is rated at 1,5 A and 125 V d.c. The 110 punchdown and bulkhead passthrough are Category 5e compliant and the direct PCB mount is Category 5 compliant. Since the standard PCB mount requires field termination, it does not carry a rating.
This new release also includes RJ45 and RJ11 cordsets. The cordset uses a standard RJ45 or RJ11 plug and adds strain relief and a locking mechanism which seals the connector when mated with an appropriate receptacle. Overmoulded and field assembled plugs are available. Designers can select from solid core, shielded PUR cable for long runs, stranded PVC for shorter 'patch' applications or for more extreme environments, PROPLEX cable with a KEVLAR jacket can be used.
