Contact-free reading of cards and similar identifiers in accordance with the standards such as Unique 125 kHz and Mifare, DESFire Mifare 13.56 MHz can be facilitated by the AXR-100/110 sensors (manufactured by EFG CZ s.r.o), which should be connected to the C-WG-0503S module.

The module provides powering the sensor, communication between the Wiegand and the sensor, and control LEDs and the buzzer.

The sensor is suitable for the door; it can be installed on the door frame. Detailed technical information on the sensor can be found at the end of this chapter.

Notes:

  1. The cable for connecting the sensor can be as long as dozens of meters (the Wiegand interface allows the length of up to 150m); preferably the cable should be shielded with the minimum cross section of 0.35 mm2.

  2. The consumption of the AXR-100 sensor from the supply voltage is specified at 112 mA, but this is impulse consumption; the average current level approximately 50 mA and it meets the specifications of the C-WG-0503S module (maximum consumptiuon from the 12 V output is 60 mA).

  3. The free inputs AI/DI4 and AI/DI5 can be utilized e.g. for connecting the temperature sensors (measuring the temperature in the room, etc.).

The properties and parameters of the AXR-100 and AXR-110 sensors.

The AXR-100/110 sensor is designed for contact-free reading (RFID) identifiers in accordance with the type of technology used: the Unique/HS (AXR-100) or the Mifare (AXR-110). The coloured LED on the front side of the sensor informs about the reading of the identifier, together with an audible signal (a buzzer controlled by connecting the terminal 3 (BEEP) with the clamp (7) GND). The LED indicates 3 statuses:

1) Blue - idle operation state.

2) Green - access allowed (controlled by connecting terminal 5 (GLED) with terminal (7) GND).

3) Red - No Entry (controlled by connecting terminal 4 (RLED) with terminal (7) GND).

Protection

IP 54 5)

  1. The median value of the pulse current is less than 60mA, so it can be directly supplied by a 12 V output in the C-WG-0503S module.

  2. This measurement is for the identifiers supplied with the sensor. Other types of ID may have a different reading distance.

  3. It has been measured on a non-metallic surface. Metallic surface can decrease the reading distance.

  4. Only for reading of a unique serial card number.

  5. The declared protection is valid only if the proper installation procedure has been followed.

Notes:

  1. The recommended mounting height is 120 cm from the floor to the bottom edge of the sensor.

  2. There is room in the rear part of the sensor for the connector and the cable.

  3. The coloured top cover (see the variants in the text above) can be fixed by its snapping onto the sensor.
