IDEC Corp. has introduced the KW2D series of smart radio frequency identification (RFID) readers. These intelligent RFID readers are designed for easy installation into the typical 22mm panel-mount holes used with machinery, are readily integrated with automation systems, and enable OEMs and end users to apply advanced authentication and authorization measures.
The IDEC KW2D series RFID readers are compact UL listed all-in-one devices installed into 22mm panel-mount holes 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 connectivity to host devices like PLCs and HMIs using Modbus TCP.
Three-color white/green/red LED lighting is clearly visible from the front and sides—even at a distance—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 color-coded key fob or card-style tags. The key fob tags are available in five colors, are durable for field conditions, and include enhanced encryption compared with other tag types.
RFID tags are low cost and passive, responding 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 15mm depending on the tag style. Several ISO/IEC communication speeds (type V, A, or F) are supported.
