Mechanical Specification

Mechanical drawings

Critical dimensions for the ORB, mounting plate and mounting hardware are given below. Full three dimensional models are available on request.

Note

All dimensions are in mm.

Mechanical Fittings

The following screws and seals are used on the ORB. Spare parts, if required are available from Senquip.

Seals
O-ring	ID121 x 3mm	To maintaing the IP rating of the enclosure, only use o-rings that have been provided by Senquip.
Gland	M20 x 1.5	To maintaing the IP rating of the enclosure, only use glands that have been provided by Senquip.

Environmental

The ORB is designed for use in harsh outdoor environments and is suitable for use in industrial, mining, fleet and agricultural applications.

The enclosure is rated to IP67, meaning that it is dust tight, with no ingress of dust permitted and watertight against the effects of immersion of up to 1m for 30 minutes. The cable gland, when fitted with suitable wiring is rated at IP68.

The chart below describes IP ratings and how to interpret them.

The ORB can be operated in temperatures between -40°C and 85°C however the internal Lithium-Ion-Polymer battery charging will be throttled at temperatures colder than -10°C and higher than 40°C.

An internal gore vent allows for pressure equalisation between the interior of the enclosure and the environment meaning that the ORB can be shipped in non-pressurised environments such as some aircraft.

Material Specification

The enclosure and all fittings have been chosen to be resistant to salt spray and common industrial chemicals such as petro-carbons. UV stabilised materials have been chosen to allow mounting in direct sunlight.
