Sherlotronics RX4-500 Receiver
The Sherlotronics RX4-500 is a reliable 4-channel long-range code-hopping receiver designed for gate automation, garage doors, alarm systems, panic activations, access control, lighting control, and other remote switching applications. Built for secure wireless operation, it is ideal for residential, commercial, and light industrial installations requiring dependable multi-channel remote control.
With four independent relay outputs, the RX4-500 allows multiple devices or functions to be controlled from compatible Sherlotronics transmitters. Each relay can be configured for different operating modes, making the receiver suitable for applications such as opening a gate, triggering a pedestrian access function, activating an alarm, switching lights, or controlling auxiliary equipment.
The receiver uses code-hopping encryption to improve wireless security by changing the transmitted code with every activation. This helps reduce the risk of code grabbing and unauthorized duplication, making it a trusted solution for secure access and automation control.
Designed for long-range performance, the RX4-500 offers up to 500 metres line-of-sight transmission range when used with compatible Sherlotronics remote transmitters. Its weatherproof ABS housing allows for protected installation in suitable outdoor or exposed areas, while the 12VDC / 24VAC power input makes it easy to integrate with many gate motors, alarm panels, and automation systems.
