ELATEC TWN4 MultiTech 2 Legic 42-P

RFID integration often forces a choice: support legacy low-frequency credentials or modern high-frequency smart cards, but rarely both in one compact module. The ELATEC TWN4 MultiTech 2 LEGIC 42-P solves this by combining 125 kHz and 13.56 MHz readers into a single embedded PCB, so a single design can handle HID Prox, MIFARE, LEGIC, NFC, and more.

Who is it for

Device manufacturers, access control integrators, and kiosk builders who need a future-proof RFID front end without redesigning hardware for every credential type. It suits industrial, medical, and retail equipment where space is limited and reliability is critical.

Main features

• Dual-frequency operation: reads both 125 kHz LF and 13.56 MHz HF tags.
• Broad HF support: LEGIC Prime, LEGIC advant, ISO 14443 A/B, ISO 15693, NFC, FeliCa.
• Broad LF support: HID Prox, EM4100, Indala, T5577.
• Flexible interfaces: USB (HID/CDC), RS232, and TTL UART for easy host integration.
• Integrated antenna and compact PCB module format.
• Field-upgradable firmware and SDK/API for custom applications.
• Two configurable LEDs and an integrated buzzer for user feedback.
• Wide operating temperature range (-25°C to +80°C) for demanding environments.

Tips

Pair the module with a custom antenna if you need extended read range, but for most embedded applications the integrated antenna is sufficient. Use the SDK to implement advanced features like secure element access or custom LED/buzzer behavior. Ensure your host provides a stable 3.3V or 5V supply to avoid read inconsistencies.
