Safely transmit power to switches and sensors in highly volatile areas. Commonly used in refineries, power plants, and wastewater-treatment facilities, these barriers use a NAMUR signal to reduce the current and voltage coming from your power supply—preventing sparks and ignition. While these barriers connect to switches in hazardous locations, they must be installed in a separate nonhazardous area, along with the power supply. As associated apparatuses for IECEx and ATEX internationally certified switches, they should be paired with items that have corresponding ratings. Mount to DIN rails inside control cabinets and electrical panels.

Barriers with a transistor signal output are faster and last longer than those with a relay output. However, they can only be used to handle DC loads. Connect them to receiving devices, such as remote displays and programmable logic controllers (PLCs).

Often used as position indicators, pump level controls, and machine limit switches, these switches actuate when tilted to a certain angle. They mount horizontally and activate when tilted downward, and deactivate when tilted up. Differential angle is the total angle from the point of activation to the point of deactivation. All combine electromechanical and solid state technologies for reliability and long life.
