208V motion sensor

[conmgt]

Hello,

I see motion sensors rated for 120/277 but none rated 208 or 240.
Does 120/277 mean multivolt/every voltage in between 120 and 277?
Does the fact that 120 and 277 use a grounded conductor meet some requirement within the sensor itself that requires a grounded conductor?
Has anyone seen a 208 or 240 volt motion sensor?
I sent Sensor Switch an e-mail but no reply yet.

A lot of your wall sensors are 120 OR 277. However, most low vaoltage power packs allow for 208.

Typically, a rating on a device that reads 120/277 means that it is rated for 120v OR 277v. A marking that reads 120-277 is ussually rated for the full range of votages from 120 through 277.

I just got a reply from Sensor Switch. They have the CMRB-6 208 that works on 208-240V.
