Linear MDT-1B MegaCode 1-Channel Block Coded Visor Transmitter, Black

Built for dependable gate and facility access, the Linear MDT-1B 1-Channel Block Coded Visor Transmitter offers secure, low-maintenance remote control for access control and security monitoring systems. As a Linear handheld transmitter in MegaCode format, each unit is factory-programmed from over 1,000,000 unique codes, dramatically reducing the chance of code duplication and unauthorized entry. The single-channel design and block-coded ID series let technicians quickly program multiple transmitters into Linear receivers or controllers by entering start/end codes — ideal for fleet rollouts.

Designed for everyday use, the MDT-1B includes two CR2032 lithium batteries with a five-year service life, a convenient visor clip, and a high-visibility operate LED. Operating at 318 MHz RF, it delivers superior range for gate, garage, and perimeter access applications. The extra top button (with removable cover) prevents accidental activation while offering a programmable function when needed. Compact and rugged, this transmitter streamlines security deployments, maintenance, and onsite monitoring.
