Switch
•
An IP67 momentary switch option can be mounted directly into this hole, for manual
activation of measurements or data transmission while on site, to confirm the site operates
correctly. This is best paired with the internal display option.
Glands
•

(5/8”)
port can fit a M16 gland directly. While PG9 is a close fit, the thread
length on PG9 glands is insufficient for the 6mm plate (with gasket). M16 glands commonly
come with 15mm thread length. Suitable M16 glands are available from
, to suit
cable diameters from 3mm to 7mm.
