Description
The Linx MS Series Keyfob transmitter is 
ideal for remote control and command 
applications. Available in 418 (standard) 
or 433.92MHz versions, it has been 
pre-certified for FCC Part 15, Industry 
Canada, and European CE (433MHz) 
compliance. This dramatically reduces 
development cost and time to market. 
The high-performance synthesized 
design provides superior frequency 
accuracy and minimizes body proximity 
effects. When combined with an LR 
or LT Series module, the Keyfob can 
operate at distances of up to 750 feet. 
Ease of use and security are dramatically 
enhanced by the on-board MS Series 
encoder, which allows instant creation of 
up to 16,777,216 (2
24
) unique addresses
without cumbersome DIP switches 
or cut traces. When paired with a MS 
Series decoder, Keyfob identity can be 
determined and button permissions established. The Keyfob is available 
with 1 to 5 buttons and can be custom labeled
