EnOcean Wireless Dry Contact Sensor

Get real-time alerts about the contact status of essential equipment, such as UPS status, security systems, fire alarms or air conditioning units

Our wireless dry contact sensors monitor the status of any equipment that has a volt-free, dry contact output, such as UPS status, security systems, fire alarms or air conditioning units. The small, energy harvesting devices use ultra-low power wireless and battery-less technology, making them easy to install and very low maintenance.

Reports live contact status
A dry contact sensor can be used to monitor the open/close status of any piece of equipment that has a contact point, or reed switch

Get updates as status changes
Know the live status and get instant updates if contact status changes

Track status over time
Monitor equipment status in you IoT platform, BMS system or other software
