T3941 – Infrared contactless RF Transmitter

long range rf transmitter

The T3941 – Infrared Contactless RF Transmitter is a high-security transmitter with rolling code technology, ideal for general activation of a receiver, generally used as an exit device.

Operating at 433,92MHz in AM/ASK modulation, the T3941 comprises an infrared-sensitive circuit and a radio transmitter. It enables the contactless, touch-free operation of gates, garage doors or any system featuring a corresponding compatible 433MHz receiver.

T3941 is an infrared device – a simple wave of the hand will activate the radio signal and thanks to its audible feedback, the user will be informed of his status.

Thanks to its 3V battery it does not require any wiring, making the installation simple and easy. The T3941 is supplied with a CR123A lithium battery providing an estimated functioning life of approx. 2 years.
