With a detachable cable you can use alternative cables, and if the cable is pulled it will pop out instead of breaking.
Ingress Protection (IP) rating
Unknown. Help us by suggesting a value.
The first number of the IP rating refers to protection against dust, while the second number refers to protection against liquid. E.g. a first number of 6 denotes that it is completely dustproof, and a second number of 7 denotes that the device can withstand full immersion in water.
can be folded
