Features: 1) Wiegand 26 transceiver unit is designed for reading the serial number of the Mifare I compatible IC cards and is a major component in RFID (Radio Frequency Identification) reader systems 2) EM reader introduction: proximity reader utilizes EM technology to read contactless EM cards. Suitable for access control, time and attendance and other card control systems. Wiegand output model interfaces with all existing Wiegand protocol access control systems 3) MF reader introduction: MF smart card reader utilizes Mifare technology to read MF contactless smart card. Contactless smart cards are used for stored value or data applications such as access control, vending, toll roads, airline ticketing, banking cards, city cards, ID cards, university cards, phone cards, park and ride cards, and prepaid metering 4) Can be applied in office/home security, personal identification, access control, anti-forgery and production control systems Specifications: 1) Power requirements: (linear regulator is recommended) a) EM: 9-12V DC at 100mA b) MF: 7-12V DC at 100mA 2) Reading range: a) EM: safe reading range for 7cm with standard H4100 card b) MF: safe reading range for 4cm with Philips Mifare I contactless smart card 3) Frequency: a) EM: 125kHz standard b) MF: 13.56kHz standard 4) Operating temperature: 22 to 150°F (-30 to 65°C) 5) Operating humidity: 0-95% relative humidity non-condensing 6) Audio/visual indication: green, red, yellow LED bar and buzzer 7) Response time: less than 0.1 second 8) Cable distance: a) Wiegand interface: 100m b) RS232 interface: 15m 9) Built-in transceiver antenna 10) Max. effective distance: up to 75mm 11) Less than 200ms decoding time 12) Low power dissipation with single power supply 13) Wiegand 26-bit interface 14) Supports Mifare I compatible IC cards 15) Built-in bi-color LED and buzzer 16) Recommended cable is Alpha 1295 (22 AWG) 5 conductor minimum stranded with overall shield or equivalent.
