When referring to pneumatic cylinders, we are seeing a need for reduced cylinder and sensor sizes. This is becoming a requirement in many medical, semiconductor, packaging, and machine tool applications due to space constraints and where low mass is needed … Continue reading
When using a T-slot or C-slot (Figure 1) magnetic field sensor to determine positioning in a pneumatic cylinder, the sensing face is oriented directly toward the magnet inside of the cylinder. But on the other side of the coin, how susceptible … Continue reading
A common request from many engineers I talk to is the need for a “faster” RFID read/write system. Usually, this is due to the fact they are increasing their overall line speed and decreasing the amount of time that a … Continue reading
A few years ago, a new gas station opened in our neighborhood situated at the edge of town. Some new customers started showing up with camouflage painted cars, especially early in the morning or late at night. They always seemed … Continue reading
The classic linear position feedback solution for hydraulic cylinders is the rod-style magnetostrictive sensor installed from the back end of the cylinder. The cylinder rod is gun-drilled to accept the length of the sensor probe, and a target magnet is … Continue reading
Roughly four sensing-related processes occur in a welding cell with regards to parts that are to be joined by MIG, TIG and resistance welding by specialized robotic /automated equipment: Nesting…usually, inductive proximity sensors with special Weld Field Resistance properties and … Continue reading
Similar to inductive sensors, capacitive sensors are available in two basic versions. The first type is the flush or shielded or embeddable version however with capacitive sensors they are sometimes referred to as object detection sensors. The second type is … Continue reading
Linear encoders – absolute or incremental? Incremental encoders are simple, inexpensive, and easy to implement, but they require that the machine be homed or moved to a reference position. Absolute encoders don’t require homing, but they’re usually more expensive, and … Continue reading
Since 2010 we have been sharing best practices, technology and industry trends. Occasionally we have even gotten back to basics with how the products we use to automate actually work. As you know, we are dedicated to the successful implementation … Continue reading
