3-A certified, these food-safe switches trigger automated controls and alarms when food-processing, pharmaceutical, and biotech lines reach a set pressure. These switches have many features that make them safe for sanitary environments because they reduce the space where bacteria could grow. A sleeve shields internal parts from water and other contaminants. Polished surfaces and smoothly welded seams make cleaning easier. Made of 316 stainless steel, they stand up to harsh cleaners and sanitizers without rusting. Rated IP67 and NEMA 6, they’re dust tight and withstand washdowns and temporary submersion.

Connect them to your line with the same quick-clamp fittings (also known as tri-clamp fittings) that are common on sanitary lines since they’re easy to take apart for cleaning. The quick-clamp end has a diaphragm that protects the switches from corrosive material and covers threads to keep them clean. The diaphragm is filled with 99.5% pure USP food-grade glycerin, which keeps the switch clean if the diaphragm fails. It’s also laser etched with the serial number to reduce crevices.

Twist the adjustable setpoint ring to make quick changes. These switches are single pole, double throw (SPDT) and can be installed to turn one circuit from off to on (normally open) or from on to off (normally closed).

All have a certificate with traceable lot number and material test report.

When these 3-A certified switches reach a set pressure or vacuum, they trigger controls and alarms in food-processing, pharmaceutical, and biotech lines. They have a sleeve to shield internal parts from water and contaminants. Their surfaces are polished and their seams are continuously welded, so cleaning is easy and there’s little room for bacteria to grow. Made of 316 stainless steel, these switches stand up to harsh cleaners and sanitizers without rusting. Rated IP67 and NEMA 6, they’re dust tight and protected from washdowns and temporary submersion.

Detect when oil rises on water, foam forms on beer, and tanks empty, triggering pumps and valves in food and sanitary lines. These switches are 3-A and European Hygienic Engineering and Design Group (EHEDG) certified since they’re easy to keep clean. Highly polished, they prevent bacteria from growing. They also stand up to hot spraying water, chemicals, and cleaners common to food plants, thanks to their PEEK probe, stainless steel body, BSPP threads, and IP ratings. Their IP67 rating also means they won’t fail if under water temporarily.

To connect to automated systems and remote displays, these switches work with IO Link and 4-20 mA analog output, making them good for hard-to-reach areas. Program the colors on the LED indicator to tell you what the switch is sensing.

USP Class tested, the plastic in these switches won’t leach chemicals. They’re also C-UL listed and CE marked to meet Canadian and European safety standards.

Use quick-clamp adapters to connect these switches to quick-clamp sanitary tube fittings.

Note: Solids and liquids must have a dielectric constant of at least 1.5 to detect them.
