Mounting Holes to Enclosure
IP67 Enclosure Ratings
The enclosure is rated for the following ingress protection.
IP6x Solid particle protection
- Dust Tight - complete protection against contact (dust tight). A vacuum must be applied. Test duration of up to 8 hours based on air flow.
IPx7 Liquid ingress protection
- Immersion, up to 1 m depth. Ingress of water in harmful quantity shall not be possible when the enclosure is immersed in water under defined conditions of pressure and time (up to 1 m of submersion).
For further details on IP ratings refer to wiki/IP_Code.
Cable Gland Fitting
If your kit did not come with a pre-fitted gland then follow these instructions to fit a ½" 14 NPT threaded gland.
- Drill a ¾ inch diameter hole in the desired location.
- Tap with a ½ inch - 14NPT for tight seal.
- Screw the gland directly into the case, seeling with a washer or suitable glue.
(Note there is no room for a backnut)
* Zymbit offers factory fitting for quantities > 50 units.
This enclosure can be mounted directly to a wall or flat surface using two self tapping screws.
