The Linear 308301 2-Channel Key Ring Transmitter is a compact transmitter designed for automatic door and gate operator applications.
This two-channel transmitter allows independent control of two compatible access points. Pressing the left button sends a channel one signal, while pressing the right button sends a channel two signal. A molded-in hole in the case allows the transmitter to be conveniently attached to a key ring.
The transmitter uses the Multi-Code format and features two 10-position coding switches, providing 1,024 possible codes for each channel. Independent channel coding allows operation of applications such as a common gate and a private door. The transmitter will only activate receivers programmed with the matching code.
