Wireless Receiver Grothe MISTRAL 400M E White

The Grothe MISTRAL 400M E White is a compact wireless receiver designed for integration in residential and light-commercial door communication and signaling systems. Operating at 868.35 MHz with a maximum effective range of up to 500 m (open field), it receives wireless signals from compatible transmitters and reliably switches connected loads. The receiver is built for AC mains operation with a 230 V, 50 Hz input and features a slim enclosure measuring 60 mm (width) × 45 mm (depth) × 120 mm (height), allowing installation in tight spaces or mounting near existing electrical equipment.

Advantages

The device offers a combination of long-range wireless reception and compact form factor, enabling flexible placement and straightforward integration into existing electrical installations. Its operation on standard AC mains voltage avoids the need for additional power supplies, while the tuned frequency of 868.35 MHz ensures compatibility with systems using the same band and stable signal reception under normal conditions. The housing and size simplify installation in distribution boxes or near entrance panels.

How to use

Install the Grothe MISTRAL 400M E White in a dry, ventilated location close to the devices it will control, and secure it inside a distribution box or on a mounting surface compatible with its dimensions. Connect the receiver to the AC mains (230 V, 50 Hz) following local wiring regulations and ensure the output leads are connected to the load or switching interface required by the application. Pair the receiver with compatible transmitters operating on the same 868.35 MHz frequency according to the manufacturer pairing procedure, and verify signal reception and control functionality before finalising the installation.

Usage recommendations

For reliable operation, mount the receiver away from large metal objects and sources of strong electromagnetic interference. Test the actual range in the installation environment, as walls and building materials can reduce radio performance. Ensure all electrical connections are carried out by a qualified electrician and comply with local safety standards.
