Wireless access control door interface RC-DCK-433

Overview
The RC-DCK-433 Wireless Door Control Kit is a professional RF solution to control and activate automatic doors, gates and access systems without wired connections between control devices and automation units. It reduces installation time, wiring complexity and cost, making it suitable for both retrofit and new installations.

Main benefits

• No wiring between devices
• Full software configuration (PC configurable via USB-C)
• Fast installation and commissioning
• High flexibility for different automation setups
• Reliable 433 MHz RF technology
• Reduced installation errors and maintenance effort

Operating band and performance
The kit operates in the 433 MHz band (operating frequency 433.92 MHz), a standard for short- and medium-range wireless links. The radio design provides stable performance, good resistance to interference and long-term reliability in industrial and commercial environments.
