Door Switch Sensor Pair

The APC NBES0303 kit includes two wired door-switch sensors that detect when a NetShelter SX enclosure door is opened or closed. They connect directly to a compatible NetBotz appliance so rack-access events are logged in real time. The 12 ft cable length suits standard rack placements without excess slack. Operators who need immediate physical-security alerts for server cabinets will use these sensors.

Environmental Operating Limits

The sensors are rated for continuous operation between 32 and 113 °F (0 to 45 °C) and 0 to 95 % relative humidity, non-condensing. They withstand storage from 5 to 149 °F (-15 to 65 °C) at the same humidity ceiling. Maximum operating elevation is 10000 ft (3000 m). Installations outside these temperature, humidity or altitude ranges cannot rely on accurate door-state reporting.

Questions about this item

Should I choose a different cable length or stick with the 12 ft version?

The 12 ft cable suits most standard rack layouts; select a different length only if your sensor must reach a door farther from the NetBotz appliance.

What does the 0–95 % humidity rating mean once the sensor is installed in my rack?

It confirms the switch will operate reliably in typical data-centre conditions up to 95 % relative humidity without condensation.
