SATEL Proof-TR4+ / -TR9

SATEL Proof-TR4+ / -TR9 is a heavy-duty radio modem. It has the IP69K rating, which is the highest protection available. It protects against ingress of dust, high temperature and high-pressure water. The product consists of this IP69K sealed housing and a radio module using either 403-473 MHz or the ISM licence-free frequency band 902–928 MHz .

Heavy-duty solution for harsh environment

SATEL Proof-TR4+ / -TR9 with IP69K-classification meets, for example, the requirements of machine control, smart farming and marine applications. It is a flexible and cost-effective solution that has profound electrical protection; both the power and data lines as well as the antenna interface are surge protected. It also has additional filtering on GNSS frequencies.

The modem is compatible with SATELLINE-EASy, -TR1, -TR9 / SATEL-EASy+ / -TR+ / -TR49 / -TR489 based products as well as several other radio protocols.

Complies with the requirements in the USA, Canada and Australia.
