Sherlo 4 Button Transmitter 403MHz
The Sherlo 4 Button Transmitter 403MHz is a compact and reliable remote control designed for secure multi-function operation of compatible Sherlotronics 403MHz receivers. With four independent buttons, this transmitter allows users to control multiple devices or functions from one convenient handheld remote.
Built with code-hopping encryption, the Sherlo 4 Button Transmitter helps improve security by changing the transmitted code with every activation. This provides stronger protection against code grabbing and unauthorized remote duplication, making it suitable for gate automation, garage doors, alarms, panic activation, lighting control, and access control applications.
Operating on the 403MHz frequency, this transmitter offers dependable wireless performance with an open-air range of up to 500 metres. Its compact keyring-style design makes it easy to carry, while the rubber-style buttons provide a positive press feel for everyday use.
Powered by a 12V GP23AE alkaline battery, the transmitter is designed for long-lasting use, with typical battery life of up to 2 years or approximately 10,000 activations under normal operating conditions. The built-in LED indicator flashes when the battery is low, helping users know when a replacement battery is required.
