Harsh Environment Potentiometers
Rated NEMA 13, these potentiometers protect against debris and splashing oil and coolant. Also known as variable output switches, they vary electrical flow to control speed, volume, and light intensity.
NEMA 6 potentiometers seal out water from temporary submersion as well as weather and washdowns.

Linear Motion Position-Measuring Transmitters
Measure the position of an object moving in a straight line. Also known as string pots, these transmitters have an extendable wire cable that measures the relative distance between two points. They convert measurements to an electrical signal for use in controlling system automation.
All are IP rated for some protection from dust. IP67-rated transmitters also seal out water when briefly submersed.

Sanitary Rotary Motion Position-Measuring Transmitters
Also known as encoders, these sanitary transmitters convey motion to an electrical signal that conveys distance, direction, and speed. They’re often used in control systems to automate servomotors, robotics, and assembly machines in sanitary environments such as food and pharmaceutical plants. Made of corrosion-resistant stainless steel, they won’t rust from frequent washdowns with harsh cleaners. These transmitters are sealed and have a highly polished surface, leaving no room for bacteria to grow and making them easier to clean. They’re rated IP67 for protection from dust, high-pressure jets of water, and submersion in up to a meter of water for 30 minutes.
To achieve a 4X resolution increase, use these transmitters with a controller that has quadrature detection.
Transmitters with three mounting holes are designed to fit on a three-hole servomotor face.
Connect transmitters to counters and controllers with cables (sold separately).
Use a flexible shaft coupling to connect the transmitter shaft to a drive shaft.
