IP67 Dual-Frequency Keypad Card Reader, Wiegand, 86 mm: overview
The CR-270 is an 86 × 86 × 16 mm keypad reader with raised, flame-retardant rubber keys, for entrances where users prefer tactile buttons or wear gloves. It shares the epoxy-potted IP67 construction and red diamond-and-line light strip of the decorative range, and it outputs Wiegand 26 or 34 to the door controller.
Three versions are available. CR-270-E reads 125 kHz EM-type cards and fobs. CR-270-M reads ISO/IEC 14443A/B UIDs (MIFARE Classic 1K/4K, DESFire, Ultralight, NTAG213/NTAG216 and CPU cards) and can authenticate with a MIFARE key before sending the UID or read MIFARE sector content. CR-270-D covers both bands, reading EM cards alongside key-authenticated MIFARE UIDs, which makes it the practical choice while a site migrates from 125 kHz to 13.56 MHz.
A configuration card sets the Wiegand mode, card key and number format at the door. The reader draws up to 200 mA at 12 V DC, reads at 0–3 cm and works from –20 to +65 °C, with anti-static design and short-circuit protection on its outputs.
Integration notes
Red is +12 V, black GND, green D0 and white D1; purple and gray take buzzer and LED control from the controller. Grounding yellow fixes the output at Wiegand 26. The keypad output format is not listed in the base specification, so tell us your controller model and we will confirm the setting before dispatch.

CR-270 FAQ
Which version suits a 125 kHz to 13.56 MHz migration?
CR-270-D reads both 125 kHz EM-type cards and 13.56 MHz MIFARE-family UIDs, so old and new credentials work on the same door while cards are replaced.
Are the keys touch-sensitive or mechanical?
They are raised rubber keys made from a flame-retardant material. The keypad sits in the same epoxy-potted IP67 housing as the card reader.
How does the CR-270 differ from the CR-260?
The CR-270 is 86 × 86 mm with raised rubber keys and adds a dual-frequency option. The CR-260 is a 90 × 90 mm keypad version offered in 125 kHz or 13.56 MHz only.
How are PIN entries passed to the controller?
Keypad entries go out on the Wiegand D0/D1 lines. Send us your controller model with the order and we will confirm the matching keypad output setting before dispatch.
