Ultra-Precision Wet-Location Limit Switches
These switches actuate with the slightest push for a high degree of accuracy. All are rated IP67 for protection from wet locations and temporary submersion. They’re often used for determining manufacturing tolerances and detecting minute expansions and contractions.

Barriers for Hazardous Location Proximity Switches
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 relay signal output are slower than those with a transistor output, but they can handle higher AC and DC loads. Because of their moving parts, they wear out quicker than transistors. Use them to turn devices on and off, such as light bulbs and small motors.
