They can be installed in a case with a threaded hole, or fitted with a suitable locking ring when uses in a punched/drilled hole. The electrical connections are made inside the case.

The PD is a solid state, screw-in dehumidifier powered from a 3V dc source.  It is silent in operation, drain free, maintenance free, has an average power consumption of 80 mW, and has a long service life.The standard version is model PD3 which uses push-on electrical connectors. Type PD2 has soldered connectors and is available on request.

The PD4 and PD5 models introduced in 2016 have a smaller capacity and are suitable for volumes up to one litre

Where a screw-in mount is not suitable the RD Series offers a flat bolt-on profile dehumidifier, also for enclosures up to two litres and measures 24 x 30 x 5.5mm. The standard version is model RD3 which is designed to be mounted on the outside of the enclosure. Model RD4 is almost identical but designed to be installed inside the enclosure to be dehumidified.
