KH2 Series RF Transmitter/Encoder and Receiver/Decoder Modules
Transmitters and Receivers for Digital Data with Integrated Encoders and Decoders
Trigger discrete actions with button presses or contact closures by using KH2 Series transmitter/encoder and receiver/decoder modules. They contain Holtek chips and LR Series RF modules. The KH2 Series provides a low level of security. It lets you send commands from multiple transmitters to distinct receivers in the same vicinity through physical addressing. Use KH2 Series modules together or with compatible Linx components for reliable one-way wireless communication at 315MHz, 418MHz or 433MHz. Compared to 2.4GHz modules, narrowband modules from Linx provide longer range and lower current consumption at a more cost-effective price.
Security
The decoder will only accept transmissions from compatible encoders with addresses that match its own. The KH2 Series allows manual addressing through 10 tri-state pins. Because the address is visible in hardware, the KH2 Series is not as secure as the MS Series and HS Series encoders and decoders, which use digital addressing. Additionally, because the KH2 Series does not use encryption or rolling code, it does not protect against intentional security threats. For protection against intentional threats, consider using the HS Series with separate RF modules.
Benefits
Reduce component count: combined transmitter/encoder and receiver/decoder form a complete module solution with only two parts
Mix and match products: use the receiver with compatible Linx keyfobs and handheld transmitters
Integrate with ease: simple hardware configuration lets you transfer raw data without protocol constraints or the need for user programming
Save power: low current consumption compared to competing modules extends battery life
Simplify design: modules and antennas are the only RF components you need; no tuning required
Streamline production: save time and money with modules that are already tested
Avoid accidental conflicts: 310 addresses help prevent identification mistakes
