Eccel Technology Ltd Quad-Tag 125 kHz RFID Module ASK Modulation Manchester Coding TTL Interface 5V RWD-QT

Eccel Technology Ltd RWD-QT is a quad-tag low power RFID module designed for industrial and electronic applications involving passive RFID transponders operating at 125 kHz frequency. It utilizes ASK modulation combined with Manchester Coding to ensure stable and secure communication.

This module supports multiple passive RFID transponder standards including Hitag 1/S, HiTag 2, EM400X/4102, and MCRF200I/123, making it versatile for identification and access control systems. The device communicates via a TTL interface and features through-hole mounting for a robust physical connection within electronic assemblies.

The RWD-QT module requires a dedicated 700μH antenna coil to operate effectively and accepts power supply voltages from +4V to +6V, typically powered at 5V. It achieves a read/write range of up to 200 mm and transmits data at a rate of 4 kbps. The supported operating temperature range of -40°C to +85°C ensures reliable function across diverse industrial and environmental conditions.

Measuring 30.5 mm in length and 18 mm in width in a DIL module form factor, this component is compact and suitable for integration within constrained spaces. Host communication is managed through a serial UART interface operating at 9600 bps with CTS flow control to manage data flow effectively.

This module is ideal for industrial automation, electronic systems requiring RFID identification, access control, and asset tracking. Its low power consumption and broad compatibility expand its applicability in embedded systems and product identification.

An evaluation kit is optionally available to assist in rapid prototyping and system integration. The product is supplied new and conforms to industrial standards for RFID modules. Explore more RFID Modules and electronic components at EnvMart for your industrial and electronic project needs.
