Industrial IP65 RFID Card Reader, Wiegand/RS485 + Bluetooth: overview
The CR-310 is built for doors and gates that see real temperature extremes: loading docks, cold stores, plant rooms and unheated perimeter entrances. It is rated for operation and storage from –40 to +85 °C, carries an IP65 rating and sits in a faceted, metal-framed housing. Outputs are Wiegand 26/34 and RS485, with Bluetooth LE 5.1 on the BT versions.
Dual-frequency versions read 125 kHz EM4100, EM4102, EM4200, EM4305 and EM4450 cards alongside 13.56 MHz credentials. At 13.56 MHz the reader is compatible with MIFARE Classic, DESFire EV1/EV2, Ultralight, Ultralight C, CPU cards and NFC Forum Type 1, 2 and 4 tags, and the card-only models also read ISO/IEC 15693 tags such as ICODE. Beyond UIDs, it can read MIFARE sector data and CPU-card content, includes anti-copy protection and rejects card emulation from NFC phones.
Setup uses a configuration card or an NFC-enabled phone, and firmware and parameters can be updated in the field. Supply is 9–15 V DC; at 12 V the reader draws about 170 mA on standby and about 190 mA while reading, with a read distance of 0–5 cm.
Integration notes
The reader is wall-mounted and ships with a 374 mm (14.7 in) cable and no logo. Run Wiegand D0/D1 to a conventional controller or use RS485 for panels and turnstile boards that poll serial readers. Keypad models (suffix K) add a touch keypad in the same 120 × 86 mm housing. The input is limited to 15 V, so 24 V systems need a step-down converter.

Where the CR-310 is used
- Cold-store and freezer-room doors where standard readers stop working
- Unheated perimeter gates and vehicle entrances in cold climates
- Loading docks and plant rooms exposed to dust, spray and heat
- Turnstile boards and panels that poll readers over RS485
Turnstile & Speed-Gate Readers: QR, RFID and Face
Turnstile card readers, QR scanners and face terminals for tripod, swing and speed gates, with Wiegand, RS485, RS232 or TTL output to the gate board.
CR-310 FAQ
Will it work in a cold store or unheated gatehouse?
Yes. Operating and storage range is –40 to +85 °C, humidity up to 90% non-condensing, and the housing is rated IP65.
What is the difference between CR-310-M and CR-310-M-BT?
Both read 13.56 MHz cards and output Wiegand 26/34 and RS485. The BT version adds Bluetooth LE 5.1, and the dual-frequency (D) builds always include it.
Can it stop cloned cards?
It has anti-copy protection and can read MIFARE sector or CPU-card content rather than relying on the UID alone. It also rejects card emulation from NFC phones.
What power supply does it need?
9–15 V DC. At 12 V, allow about 190 mA per reader while reading; 24 V systems need a step-down converter.
Do the keypad models read ICODE tags?
No. The keypad models are specified for ISO/IEC 14443A/B credentials only; ICODE (ISO/IEC 15693) reading is listed for the card-only models.
