TopWorx GO Switch Model 81-10528-A2 Proximity Limit Switch

The TopWorx GO Switch Model 81-10528-A2 is a robust, leverless proximity limit switch designed for reliable position sensing in harsh industrial environments. Manufactured by TopWorx (a division of Emerson), this general-purpose industrial control device utilizes magnetic proximity technology to detect the presence of ferrous targets without physical contact, ensuring long-term durability and minimal wear. Key features include a stainless steel housing for corrosion resistance, hermetic sealing for protection against contaminants, and versatile wiring options with color-coded leads (red, black, blue) for easy installation. It is ideal for applications such as valve position monitoring, cylinder end-of-stroke detection, and process automation in industries like oil and gas, chemical processing, and manufacturing. Advantages over traditional mechanical switches include no moving parts, reducing maintenance needs and extending service life, with high resistance to shock, vibration, and extreme temperatures. Drawbacks may include higher initial cost compared to basic mechanical switches and the need for a magnetic target. This model supports AC voltages up to 600VAC and is UL and CE certified for safety. Based on image analysis, the unit appears new or unused, with intact packaging and no visible wear, including a serial number (e.g., 16092115360AY) and model details on the faceplate. No parent/child assets are evident in the images.
