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.
Fig. 1. An example of connecting the AXR-100/110 sensor to the C-WG-0503S module
Notes:
-
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.
-
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).
-
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).

-
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.
-
This measurement is for the identifiers supplied with the sensor. Other types of ID may have a different reading distance.
-
It has been measured on a non-metallic surface. Metallic surface can decrease the reading distance.
-
Only for reading of a unique serial card number.
-
The declared protection is valid only if the proper installation procedure has been followed.

Notes:
-
The recommended mounting height is 120 cm from the floor to the bottom edge of the sensor.
-
There is room in the rear part of the sensor for the connector and the cable.
-
The coloured top cover (see the variants in the text above) can be fixed by its snapping onto the sensor.
