IDEC KW2D series RFID readers

IDEC Corporation has announced the KW2D series of smart radio-frequency identification (RFID) readers, which are designed for easy installation into the typical 22 mm panel-mount holes used with machinery and are readily integrated with automation systems.

The  RFID readers are compact, UL-listed, all-in-one devices installed into typical 22 mm panel-mount holes right along with other switches, buttons and lights. They maintain IP65/67 water-, dust-, and oil-proof ratings, and feature push-in power supply terminals. A built-in Ethernet port facilitates easy connectivity to host devices like PLCs and HMIs using Modbus TCP. Three-colour white/green/red LED lighting is clearly visible from the front and sides to indicate standby, successful verification or error respectively, while a built-in auxiliary buzzer provides audible feedback of successful and error conditions.

Users can mix and match various RFID tag formats: commercial-style cards, wristbands, stickers, and IDEC-supplied colour-coded key fob or card-style tags. The key fob tags are available in five colours, durable for field conditions, and include enhanced encryption compared with other tag types.

RFID tags are passive devices that respond to a short-range radio signal generated by the RFID reader when the two are in close proximity. The KW2D operates at standard 13.56 MHz high-frequency (HF), providing a reading distance of up to 15 mm depending on the tag style. Several ISO/IEC communication speeds (type V, A or F) are supported.
