Power Load Switches
-
Low-resistance power load switches offer reliable overcurrent and thermal protection. They are designed for general-purpose power protection or for applications such as USB, hot-swap and power distribution. The power switches come in 1- or 2-channel versions with fixed and adjustable overcurrent limit. Some include a USB charge controller specifically designed to optimize USB host applications.

Waveguide Switches
-
Waveguide switches are electromagnetic switches with hollow circular or rectangular cross-sections and are used for routing RF energy in microwave communications, broadcasting, and in radar applications. Waveguide switches can be used to transfer both power and communication signals, and the bandwidth of a waveguide is in relation to its size, and thus always referred to by its size (e.g. WR112, WR90, WR75 etc.). Compared to coaxial switches, waveguides can route extremely high power signals over a narrow bandwidth at low to high frequencies, and now Lightweight Waveguide series is available.

Managed Ethernet Switches
-
CommFront offers a range of rugged, industrial-grade, managed and unmanaged Ethernet Switches. These Industrial Ethernet Switches have been designed for harsh industrial environments and withstand a wide temperature of -40°F to 185°F (-40°C to 85°C), and they come with the options of 10/100/1000M for both Fast and Gigabit Ethernet networks. In addition, our advanced, rugged, industrial-grade, Fast and Gigabit Ethernet Switches support both point-to-point and multi-drop (daisy-chain or self-healing redundant ring) fiber optic networks, which are designed to cover large areas. These industrial Ethernet Switches support up to 255 fiber nodes, and each fiber node can extend the Fast and Gigabit Ethernet data up to 100 miles or 160 km. When configured as a ring network, the built-in self-healing feature allows the Ethernet data to be transmitted clockwise or counterclockwise; therefore, failure of any individual converter will not affect other devices located on the same ring, making the entire Ethernet network more robust and reliable.

Capacitive Level Switches
VEGACAP, VEGAPOINT
-
In capacitive point level detection, the sensor and vessel form the two electrodes of a capacitor. Any capacitance change caused by a level change is converted into a switching signal. Thanks to the shortenable cable and rod versions, level switches can be perfectly adapted to any application. They are often used for overfill or dry run protection as well as oil/water or foam detection.

Belt Alignment Sensors and Misalignment Switches
-
Electro-sensors belt alignment sensors are mounted along the conveyor belt that needs to be monitored for misalignment. The rub block assemblies are mounted so that the brass surface area is in-line with the edge of the conveyor belt. When the belt wanders it then rubs up against the brass block. The contact with the belt creates friction and heat that the sensor in the brass block records as a rise in temperature.
