RFID coil antennas

Priority 1 Design carry a stock of these RFID coil antennas. Our RFID coil antennas have been designed by us
specifically for our RFID readers and transponders but can easily be used by hobbyists and professionals to
create their own RFID designs.

RFIDCOIL-49A View Prices	RFID coil Specifications: Winding Type   Unsupported Bondable magnet wire Inductance at 125Khz   2.8 mH   nominal Coil Resistance   63 ohms     +/-  1 ohm Wire diameter   0.09 mm Coil inside diameter   46 mm +/- 0.5mm Coil outside diameter    49.0 mm  +/- 0.5mm Coil Width   1.5 mm +/-  0.2mm This coil was designed to give our rfid readers longer read range. Typical read distances based on our example circuit are 8cm for keytags and 10cm for rfid cards. View an example rfid reader circuit using this coil antenna.
RFIDCOIL-100A View Prices	RFID coil Specifications: Winding Type   Unsupported Bondable magnet wire Inductance at 125Khz   2.8 mH   nominal Coil Resistance   42 ohms     +/-  2 ohm Wire diameter   0.125 mm Coil inside diameter   100 mm +/- 0.3mm Coil outside diameter    102 mm  +/- 1mm Coil Width   2 mm +/-  0.3mm A 10cm coil allows for a larger field pattern and slightly larger read ranges over our 49mm antennas. especially when larger tags are being read.
RFIDCOIL-160A View Prices	RFID coil Specifications: Winding Type   Unsupported Bondable magnet wire Inductance at 125Khz   2.7 mH   nominal Coil Resistance   19 ohms     +/-  1 ohm Wire diameter   0.2 mm Coil inside diameter   160 mm +/- 0.5mm Coil outside diameter    163.3 mm  +/- 0.5mm Coil Width   2.3 mm +/-  0.4mm This coil was created for our RFIDLOG series of rfid data loggers. Its large 16cm diameter allows for greater read range than a smaller antenna will allow. Its also suitable for use with our RFIDRW-E series of readers with only a slight addition to the tuning capacitor. View an example rfid reader circuit using this coil antenna.
RFIDCOIL-250A View Prices	RFID coil Specifications: Winding Type   Unsupported Bondable magnet wire Inductance at 125Khz   2.7 mH   nominal Coil Resistance   8.7ohms     Wire diameter   0.4 mm Coil inside diameter   250 x 250 mm Coil outside diameter    260 x 260 mm Coil Width   3 mm  A  25x25 cm coil allows for a larger field pattern and longer read ranges. When connected to out RFIDRW-E-232E enhanced reader this antenna allows typical read ranges of 27cm for a 32mm FDXB disc tag.
