Terminal Block and Connector Solutions Take Sensors and I/O Points Out to More and Different Devices and Applications

The speed at which software features and tools are introduced makes it tempting to think that hardware doesn’t evolve. That would be a mistake. As more users get hip to fieldbuses, Ethernet and wireless—and as these technologies get progressively less expensive—these innovators are taking sensors and I/O points out to more and different devices and applications where they haven’t been used before.

Consequently, this is fueling revived interest in and implementation of many terminal block and connector products, as well as demand for newer solutions as users try to meet previously unexpected needs they’re encountering in these new environments.

 Connection Systems Fit for Water
Mini-Fit H2O weatherproof, compact connection system is designed for wire-to-wire applications to 9.0 A per circuit. IP67-rated, it consists of plug and receptacle assemblies and male and female crimp terminals. The plug and receptacle assemblies have a pre-installed interface and wire seals, for a lower applied cost compared with connectors with manually installed seals. It is suited to tight-space applications, such as those in automotive, lighting systems and medical devices.
