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.

Check your indoor air quality (IAQ) by measuring the amount of particles present. These counters are often used to monitor dust levels in workshops, check for particles in classrooms, and measure filter efficiency in HVAC systems. The sensor probe detects and identifies particles of six different sizes, helping you confirm that your clean room complies with ISO Class requirements. First, use the zero count filter to establish a baseline before taking a sample. Then, either measure the amount of air particles detected within a set time range or the amount of air particles detected within a certain air volume. Counters store up to 10,000 readings in their internal memory, and you can transfer data to your computer via Ethernet or USB connection—no special software required. Compact, lightweight, and battery powered, these counters are portable and able to operate in tight spaces. They’re CE marked as compliant with European health, safety, and environmental standards.
