It integrates a 3-color LED display for status indication and connects to a PC or control system via a 1.8 m USB 2.0 cable (Type A) or an optional RS232 interface. The reader is powered over the USB bus, drawing 0.15 A typical / 0.3 A max at 5 V. The reader is built for cabinet installation — four M4 screws through the 90 x 62 mm face, with a 23.5 mm depth behind the panel. The IP65 front rating means the exposed face handles washdown and dust ingress; the housing is PC-GF (glass-filled polycarbonate) and silicon-free, so it's safe for paint-shop or clean-room environments where silicone contamination is a concern.","metaTitle":"Siemens 6GT2831-6CA50 SIMATIC RF1040R Access Control Reader,","metaDescription":"Siemens SIMATIC RF1000 Access Control Reader RF1040R, LF 125 kHz & HF 13.56 MHz, USB & RS232, IP65 front, -25 to +55 °C.
