The SICK WT100L-E1141 is a passive low-frequency (LF) RFID tag designed for reliable close-range identification in harsh industrial environments. Operating at 125 kHz, it uses inductive coupling for data transmission, ensuring stable performance even in metallic or high-interference settings. Encapsulated in a cylindrical stainless steel housing, this tag offers exceptional resistance to mechanical stress, high pressure, extreme temperatures, and chemicals. Its threaded M5 design allows for secure mounting, making it ideal for tool identification, asset tracking, and process control in manufacturing, automotive, and machining applications.
