Compact format
An ultra-flat 70 × 50 × 15 mm design, smaller than a bank card.
The SU-CD7 is the ultra-flat slave version of the range: a single unit with built-in sensors, no external probe, measuring 70 × 50 × 15 mm and weighing 50 g. It communicates over LoRaWAN only and is designed for indoor or sheltered installation.

Highlights
An ultra-flat 70 × 50 × 15 mm design, smaller than a bank card.
Low-power design: fewer site visits and lower operating costs.
Reliable low-power data transmission, up to 500 m depending on the environment.
Light and compact, it even fits behind a splice tray inside a closure.
Description
Its compact, lightweight format allows quick and discreet installation wherever a standard enclosure would be too bulky. In a telecom chamber it clips behind a splice tray to monitor the opening of a fibre splice closure.
It sends its alerts over LoRaWAN to an MSU-MD7 master unit, which forwards them over LTE-M, and runs on a 3 V coin cell for up to 10 years.

Answers to the most common questions before choosing this device.
It is designed for indoor or sheltered use (IP65 rating). For outdoor use, the MSU-SD7 with its IP68 enclosure is a better fit.
Over LoRaWAN, to an MSU-MD7 master unit or a gateway, which forwards it to the monitoring platform.
Around 500 m over LoRaWAN, depending on the environment.
No. The SU-CD7 is a single unit with built-in sensors and no external probe.
