Dual-Frequency 125 kHz/13.56 MHz Wiegand 26/34 Reader Module: overview

The LF-110 is a dual-frequency 125 kHz/13.56 MHz reader module with Wiegand 26/34 output, built for OEMs and integrators who put readers into door stations, turnstiles, elevator panels or intercoms on sites where 125 kHz fobs and 13.56 MHz smart cards are both in use. One 60 × 35 mm board picks up EM4100/TK4100 credentials as well as ISO/IEC 14443A cards such as MIFARE Classic 1K/4K, MIFARE Ultralight, MIFARE DESFire EV1 and NTAG, then hands the card number to your controller as Wiegand 26 or Wiegand 34.

That makes it a practical part for phased credential migrations: existing EM4100 fobs keep opening doors while new users receive 13.56 MHz cards, and the access controller sees a single Wiegand stream. Output is the card number; if a project needs encrypted MIFARE sector or DESFire application data, specify a secure-read module instead.

Rated read distance is more than 20 mm and varies with the credential and with whatever sits behind the board, so test inside your own enclosure. The module operates from –10 to +70 °C at 15–90% relative humidity.

Integration notes

Seven 2.54 mm pitch pins carry power (VCC, GND), Wiegand DATA0 and DATA1, a Wiegand 26/34 format-select line, and buzzer and LED lines. Supply is rated at 5 V DC (±5%) with current below 200 mA; a 12 V build is also listed, so state your supply rail when you request a quote and we will confirm the matching version.

Where the LF-110 is used

  • Apartment door stations where legacy EM fobs and new MIFARE cards must share one Wiegand input
  • Elevator car readers accepting 125 kHz tenant fobs and 13.56 MHz staff cards
  • Turnstile and speed-gate reader heads wired to a Wiegand 34 controller port
  • OEM wall readers and intercom panels built around a single dual-band board
Elevators

Elevator Access Control Readers

Elevator card readers for car panels and lift lobbies: anti-clone encrypted cards, QR codes for visitors, Wiegand or RS485 output to the floor controller.

LF-110 FAQ

Which card technologies does the LF-110 read?

At 125 kHz it reads EM4100, TK4100 and compatible credentials. At 13.56 MHz it reads MIFARE Classic 1K/4K, MIFARE Ultralight, MIFARE DESFire EV1, NTAG and compatible ISO/IEC 14443A cards, and sends the card number over Wiegand.

How do I switch between Wiegand 26 and Wiegand 34?

Pin 5 (WG26/34) selects the output format. Set it to the bit length your controller expects; pins 3 and 4 (D0, D1) carry the Wiegand data.

What supply voltage does the module need?

The module is rated at 5 V DC (±5%) with operating current below 200 mA. A 12 V build is also listed, so tell us your supply rail and we will confirm the matching version before you finalize the power design.

What read range should I expect?

The rated read distance is more than 20 mm. It changes with the credential type and with metal or other materials near the board, so verify it in your final housing.

Can the board be customized?

Yes. The module can be adapted to project requirements; include your controller interface, card types and supply voltage in the RFQ so we can confirm what is possible.
