Sanitary Pressure Switches

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 material certificate with traceable lot number and a calibration certificate traceable to NIST.

Sanitary Finger-Touch Switches


With Wire Leads	With 5-Pole M12 Connection


Blank	On/Off	Power Symbol	Start	Stop

With just a light touch, these switches turn circuits on and off in sanitary areas—even when you're wearing gloves. They're ideal for environments that require frequent cleaning, such as food and pharmaceutical plants. Their smooth, crevice-free surfaces are easy to clean and prevent bacteria buildup. Rated IP69K, they withstand high-pressure, high-temperature washdowns. They help you comply with European Hygienic Engineering and Design Group (EHEDG) sanitary standards.

These switches use IO Link, so you can change settings, view outputs, and receive error messages from a connected programmable logic controller (PLC) or computer. Commonly used on production lines, they alert your team to equipment issues as soon as they occur.

Sanitary Level Sensor Switches

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.

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

Sanitary Pressure and Vacuum Switches

When these 3-A certified switches reach a set pressure or vacuum, they trigger controls and alarms in food-processing, pharmaceutical, and biotech lines.

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.

Sanitary Photoelectric Sensors

Maintain sanitary standards—these sensors have smooth surfaces without crevices, so they prevent bacteria from building up and are easy to clean. You’ll find them in food, beverage, and pharmaceutical applications. Made of stainless steel, they won’t corrode from frequent cleanings. All are IP68 and IP69K rated for protection against temporary submersion and high-pressure, high-temperature washdowns. Because they’re photoelectric, they don’t make contact with items like other actuators do. Instead, they use light to detect objects that are moving quickly. These sensors have a plug, which connects to cables with a socket (sold separately), so you can quickly connect and disconnect the sensor. Install them with brackets, clamps, extension tubes, or mounting adapters (all sold separately).

With 4-Pole M12 Plug

Direct Sensing—Direct-sensing sensors project light onto an object and then detect the reflection to actuate. The transmitter and receiver are in the same housing, so these sensors fit in tight spaces.

Receiver Sensor—Receiver sensors detect an object when it passes between the sensor and the included reflector, interrupting the beam. They have a longer sensing distance than direct-sensing sensors.

Sanitary Electronic Insertion-Mount Flow Switches

Easy to clean and install, these flow switches are 3-A certified to meet sanitary design standards and insert into your line with a quick-clamp mounting adapter (sold separately). They have a smooth probe, and unlike flow switches that measure with a paddle or turbine, these don’t have moving parts for contaminants to get stuck in. Rated IP67 and IP69K, they withstand temporary submersion and high-temperature, high-pressure washdowns. The mounting adapter attaches to a quick-clamp tube tee or outlet (often called tri-clamp fittings) in your large-diameter tubing system using a gasket and clamp (not included), so you don't need to disassemble your line for inline installation. This mounting adapter is also easy to remove and clean.

They send digital signals to your programmable logic controller (PLC) to activate automated controls or alarms when they reach a set flow rate. To calculate the flow rate, they generate a small amount of heat, then measure the cooling effect your liquid or gas has on it. This makes them ideal in applications with fluctuating temperatures. Use the buttons on the display to adjust the set point and other settings. They’re accurate in any mounting position.
