This transmitter allows you to detect status changes (ON/OFF) on dry contact interfaces.As soon as a contact is made, the transmitter immediately sends a message. This transmitter is particularly designed for harsh environments (IP 65). The TX CONTACT SIGFOX 300-022 is self-powered with a D type 3,6V Lithium battery. Depending on data transmission periodicity, battery life can reach up to 15 years autonomy.

This transmitter is smart

It embeds two optional features to save battery and facilitate its use :

Report by Exception function : it allows you to set low and high alert thresholds to send an automatic frame if the temperature value exceeds or is above the thresholds.

Time Window Update : you can remotely modify your transmitter’s configuration from the Sigfox backend, no more onsite manual intervention to reboot the transmitter to retrieve its new configuration.
