Anti-Copy Encrypted Touch Keypad Card Reader, 93 mm: overview
AX-140 pairs a touch keypad with encrypted 13.56 MHz card reading in a 93 × 93 × 19 mm square housing. It suits card-plus-PIN doors in offices, residential buildings and service areas where copied cards have been showing up, and it connects to the controller as an ordinary Wiegand reader.
Protection comes from the card system. Cards are prepared under the reader's key with a standalone issuing program, and the access software on the controller side is left as it is: it simply enrolls the Wiegand number the reader sends. Each card can carry a validity period and a use-count limit for temporary users.
Card data is received in under 120 ms once a card enters the 0–5 cm read zone. The electronics include ESD and mis-wiring protection, and the reader is designed to cope with metal surroundings and neighboring readers, which helps on steel door frames and in dense reader banks.
Integration notes
Supply 12 V DC ±5%, ≤ 200 mA. Wire green (D0) and white (D1) to the controller, with purple and gray as beeper and LED control inputs. A configuration card sets the key, Wiegand format (26, 34 or 66-bit), output content and read mode; grounding the yellow lead forces Wiegand 26. We confirm the firmware build, card supply and issuing-software language for your project before quoting.

AX-140 FAQ
Does the access control software need changes?
No. Cards are prepared with the standalone issuing program, and the controller receives a normal Wiegand number that it enrolls like any other card.
How does AX-140 differ from AX-150?
Both use the same 93 mm housing and card system. AX-140 adds a touch keypad; AX-150 is card-only.
What is the read range?
0–5 cm, depending on the card and the installation. Card data is received in under 120 ms once the card is in range.
Can it be mounted on a metal door frame?
The reader is designed to resist metal shielding and interference from nearby readers. Range on metal can still drop, so test with your own card type before a large rollout.
Which Wiegand formats does it support?
26, 34 and 66-bit, chosen with a configuration card. Tie the yellow lead to GND to force 26-bit output.
