m-e modern-electronics 41385 Wireless Micro Converter for Door Intercom Systems

The m-e modern-electronics 41385 Wireless Micro Converter stands out as a compact solution for integrating wired potential-free contacts into existing wireless door intercom ecosystems. Unlike bulky adapters that require complex wiring or external power, this unit operates on a single CR2032 battery and installs discreetly inside standard flush-mount boxes, making it ideal for retrofits where running new cables is impractical.

Highlights

• Converts a wired potential-free contact signal into a wireless RF command
• Compatible with m-e VISTADOOR and m-e VISTUS wireless door intercom systems
• Operates on 433 MHz frequency with up to 100 m open-field range
• Powered by a single CR2032 battery with approximately 2 years of life
• Supports contact voltages up to 24 V AC/DC and switching currents up to 1 A
• Compact, concealed installation in standard flush-mount boxes

In daily use

Installation is straightforward: connect the potential-free contact (e.g., a doorbell button, relay output, or sensor) to the converter's input terminals, insert the included CR2032 battery, and pair the unit with your m-e wireless receiver. Once paired, any activation of the wired contact triggers a wireless signal that can ring a chime, activate a camera, or trigger an automation routine. The converter's low power consumption ensures years of maintenance-free operation, and its plastic housing protects the electronics from dust and minor impacts. With an operating temperature range of -20°C to +50°C, it is suitable for both indoor and sheltered outdoor applications.
