When you think about industrial machines—whether it’s a robot in a factory or a tractor in a field –you probably picture arms, wheels, and engines. But some of the most important parts are small. One of those is the rotary position sensor.
It tells a machine exactly how far something has turned or moved. And when that machine is working in a dirty, wet, or tough environment, that little sensor has to be built to survive. That’s where an IP67-rated rotary sensor comes in.
What’s a Rotary Sensor?
At its core, a rotary position sensor measures angle of movement—how far something has turned, and in which direction. Basic, but extremely important. Think of it like the machine’s sense of direction. It sends signals to let the system know what’s moving and how much.
But there’s one thing, machines don’t always operate in clean, dry, air-conditioned spaces. They’re out in fields, on factory floors, in rains, dust, grease, and sometimes worse. That’s why IP67 matters. The “IP” stands for Ingress Protection, and the “67” rating means the sensor is completely dustproof and can withstand brief immersion in water. It’s tough enough for the real world.
Some are even non-contact, meaning they don’t rely on physical contact between parts to measure movement. That matters because it means less wear and tear and a significantly longer life.

Where do these sensors actually get used?
You’d be surprised at how many places rotary sensors are used. Once you start looking, they’re everywhere.
- Robotics
Robots need to know the exact location of every joint, wheel, and arm at all times. A non-contact rotary sensor helps them move smoothly and accurately. These sensors ensure that a robotic arm picks up an object from the correct spot and places it down exactly where it should be. And because there’s no fiction, they last a long time without needing much maintenance.
- Heavy Equipment (Farming, Construction)
If you’ve got a machine working in the mud, hauling heavy loads, or digging trenches, you need something that won’t quit when the weather turns bad. A durable rotary sensor helps control everything from bucket angles to steering systems. And it continues to do its job even when things get messy.
- Factory Equipment
Factories run non-stop, and timing is everything. Packaging lines, robotic arms, and conveyor systems all rely on sensors to keep things moving just right. A rotary position sensor with both analog and digital outputs fits seamlessly into modern automation systems—and thanks to its rugged design, it remains unaffected by dust, oil, or vibrations.
Why do people pick IP67 sensors?
Here’s why engineers , machine builders, and operations people keep coming back to IP^7-rated rotary sensors-
- They can take a beating
Dust, water, heat, cold—these sensors are built to keep working through it all.
- They’re accurate
A high-precision rotary sensor gives machines the right information at the right time. That means smoother motion, better results, fewer mistakes.
- They last
For the non-contact design, they don’t wear out easily. One sensor can last for years even with heavy daily use.
- They go with other tech
With both analog and digital outputs, these sensors can connect to a wide range of control systems.
- They’re ready for the outdoors
Whether it’s on a wind turbine or a piece of farm equipment, these sensors are built to handle the elements.
Who should be using these sensors?
If your machines are in the real world—or performing tasks that require reliable, accurate motion tracking—then yes, you should consider purchasing a multi-turn rotary position sensor with an IP67 rating. These are just a few industries where they really shine-
- Solar and wind energy- Track panel angles or turbine blade positions with precision, no matter the weather.
- Warehousing and Material Handling – Keep forklifts, cranes, and storage systems running safely and smoothly.
- Medical and Lab Equipment- Clean, quiet, and reliable. Non-contact sensors are ideal where mechanical noise or wear can’t be tolerated.
- Marine and Offshore work – Saltwater and constant movement demand sensors that are completely sealed and corrosion-resistant.
- Construction and Farming – Your equipment doesn’t stop for rain or dust–neither should your sensors.
The bottom line
If your equipment needs to track rotation or movement—and it operates in rough, wet, or dirty conditions — you need a sensor that’s up to the task. An IP67 rotary position sensor is one of those small things that can make a big difference in how your machines perform, day after day.
These sensors not only survive tough environments—they operate effectively in them. They’re accurate, reliable, and built to last. And when you can trust your sensors, you can trust your machines to do what they’re supposed to do. If you are looking for something proven and built for industrial use? Head over to Briter Encoder. We offer tough, dependable multi-turn rotary position sensors with an IP67 rating, ready for whatever your job throws at them.
