SM-5527 2.45Ghz RFID Omni-directional Reader

The SM-5527 Active RFID Omni-directional Reader operates at 2.4 GHz with an external 2dBi omni-directional antenna. Read distance of up to 100 meters (depends on active tag signal output) is auto-regulated or adjustable and the reader comes with a powerful API for third party software integration. The SM-5527 Active RFID Reader has a tough high quality waterproof IP55 housing that is designed for use in rough environments.

The type of power supply and desired interface (RS-232, Wiegand 26/34) must be specified at time of order. Designed for use in access control, wander management, student attendance, people tracking and access management and mining applications.
