K12-PC1LPX 1-Channel Learning Code Wireless Remote Control Kit – 433MHz,

The K12-PC1LPX is a complete 12V single-channel wireless remote control kit designed for on/off switching of electrical devices at a distance. The kit pairs a 433MHz receiver module with a handheld transmitter, allowing users to control lights, motors, door openers, and other 12V equipment without running control wires. A defining feature of this model is its learning-code capability: the receiver can memorize the code of one or more compatible transmitters, so users can add extra remotes or replace a lost one without replacing the entire receiver.

The receiver operates from a 12V DC supply and draws approximately 8mA in standby, keeping idle power consumption low. Its 433MHz operating frequency is the most widely used band for low-cost remote control in consumer and industrial applications, and the receiver sensitivity is specified at -95dBm, which supports stable reception even in electrically noisy environments. The output is a single-channel relay with a rated contact capacity of 10A, and the module supports three selectable operating modes—self-locking (toggle), interlocking, and jog (momentary)—configured via a jumper on the board. A fourth timer mode is also indicated on some documentation but is marked as requiring testing.

The kit is intended for home automation, electric door and shutter control, small industrial equipment, lighting control, and motor switching. The receiver board measures approximately 35 × 32 × 19mm, and the housing measures 40 × 40 × 25mm, making the module compact enough for installation in tight enclosures. Operating temperature is rated from -10°C to +70°C, suitable for typical indoor and sheltered environments. The kit is a passive switching solution—it does not include sensors, Wi-Fi, or smartphone connectivity; control is strictly through the paired RF remote(s).
