Linear 414001 Four-Channel Multi-Code Visor Transmitter – 300 MHz

The Linear 414001 4-Channel Visor Transmitter is a compact, portable remote designed for reliable access to gate and door operators. Worn on a visor, it keeps control within reach while you drive or walk up to an entry point. Each of the four buttons activates a distinct channel, and raised dimples help you identify the correct button by touch, which can be especially handy in changing light or quick-access moments.

Powered by a 9-volt battery, this transmitter is built for everyday use and features a straightforward code system. It employs two 10-position coding switches per channel, offering up to 512 unique codes for each channel. The device will only activate receivers that share the same code, helping prevent cross-activation in environments with multiple remotes.
