The new Eco Plus series at a glance:

The Eco Plus Series comprises a range of motion and presence detectors in different versions. The MD/PD-8 and MD/PD-24 with 360-degree motion and presence detectors offer functions in top STEINEL quality. Each equipped with an 8 or 24 m range, they are versatile in use.

Motion detector

MD-8 ECO and MD-24 ECO

Motion detector with COM1 interface for switching light

- Motion detection and light measurement
- Full and semi-automatic mode
- Push button input
- Parallel connection of up to 10 sensors via L'
- IP 20 (flush-mounted and ceiling-mounted sensors) and IP 54 (surface-mounted sensors)


Presence detector

PD-8 ECO and PD-24 ECO

Presence detector with COM1, KNX and DALI-2 IPD interface

- Motion, presence detection and light measurement
- Presence detector function

Magnet mechanism

Fast and uncomplicated assembly

Mounting the MD/PD-8 ECO and MD/PD-24 ECO motion and presence detectors is quick and easy. After installing the load module - regardless of whether it is a surface-mounted or flush-mounted version - the sensor head can simply be placed on the load module with just one "click" thanks to the magnetic mounting mechanism and can also be put down again if required. This not only makes initial installation quick and uncomplicated, but also simplifies subsequent adjustment of the detection range using the cover shells included in the scope of delivery.
