Import Es551b Series Super Sensor — Buy in Bulk from Supplier in China

The ES551B series Super Sensor is a compact, rechargeable security device designed for asset tracking and alarm notification. It features a T-type signal input port compatible with standard sensors and recoilers, a 360-degree rotatable socket, and a built-in 95dB alarm with ±5% tolerance. The unit includes a power switch, low-battery indicator, external power detection, and a RESET button for factory reset. Its MINI USB charging port supports up to 4A maximum current, and the internal lithium battery offers either 7-day or 1-year standby modes, selectable at purchase.

The sensor is constructed for industrial environments, with an IP-rated housing not specified but implied by its operational robustness. It includes a 3M adhesive tape for surface mounting and is compatible with TIMING clamp accessories for securing mobile devices and tablets. It works with DP1155 wall and DA1850 desktop display holders, allowing integration into existing monitoring setups. The LED indicators provide visual status feedback for alarm states, and password protection via IR remote key prevents unauthorized arming or disarming.
