he WE-T241-C is a card-type positioning tag developed by Hainan World Electronic Science And Technology Co., Ltd. using ultra-wideband (UWB) technology. It supports high-precision positioning through TDoA, ToF, and AoA methods, with auxiliary positioning via BLE, barometer, and three-axis accelerometer.
The tag supports active SOS alerts, low battery alerts, and prolonged inactivity alerts, with vibration and buzzer notifications. It features a LoRa module for long-range device communication.
The tag supports both badge-style and armband-style wear, with built-in RFID access control. It features IP67 protection and meets explosion-proof standards (Ex iB IIC T6 Gb/Ex iB IIIC T80°C Db), making it ideal for industrial, power, and construction applications.
