125 kHz RFID Circular Antenna Ø42mm: IND125-D42

IND125-D42 is a circular winded coil wire for use with Sonmicro 125 kHz RFID modules.

With a nominal inductance of 860µH (±2%) and an internal resistance of 10 ohms (±10%), the IND125-D42 is optimally designed for a variety of 125 kHz RFID applications. Its practical dimensions, featuring a diameter of 42mm, a slim profile of 3.3 mm in height, and a thickness of 2.0 mm, making it ideal for a wide array of installations without compromising reading range.

Additionally, the coil wire extends from both ends of the wound coil, with each end featuring a 6cm wire length and a 1cm tinned lead for soldering, facilitating easy connectivity and installation.

Connector Option:

Optionally, this antenna comes with an approximately 8cm cable featuring a connector equivalent to the Molex Mini-Spox Series soldered to the antenna. The connector is compatible with corresponding mate parts (2.50mm) or standard pin headers with 2.54mm pin spacing.
