12-Key Long-Range RF Remote Transmitter

Reliable Multi-Channel Control

The R101 is a portable 12-key RF remote transmitter built for applications that require multiple independent wireless commands from one handheld controller. Its clearly numbered keypad makes channel selection fast and intuitive, while the rugged blue enclosure is designed for regular use in industrial, commercial and custom automation environments.

Long-Range RF Performance

Supporting both 433 MHz and 315 MHz frequencies, the transmitter uses ASK modulation with EV1527 or HS2260 encoding. With transmitting power of +13 to +15 dBm, it can achieve a control distance of up to 200 meters in open space. Actual range may vary depending on the paired receiver, antenna, obstacles and local interference.

Key Features

• 12 individually numbered buttons for multi-channel control

• Available for 433 MHz or 315 MHz RF systems

• Compatible with EV1527 learning code and HS2260 fixed code

• ASK wireless modulation

• Up to 200 m transmission distance in open space

Typical Applications

The R101 can be paired with compatible receivers for motor controls, doors and gates, lighting systems, pumps, access control equipment, industrial machinery and custom wireless switching projects. Its 12-button layout is especially useful when several devices, channels or operating functions need to be controlled from a single transmitter.

Integration Notes

For reliable operation, select a receiver with the matching frequency and encoding type. The final wireless range depends on the receiver sensitivity, antenna placement, installation environment and surrounding RF conditions. Custom labeling, frequency and coding configurations may be available for OEM projects.
