Dry contact sensors

Get immediate alerts about the status of essential equipment

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.

Get accurate, reliable status updates

The sensor simply connects using a push-wire and sends instant open/close updates if the contact status changes.

Solar-powered with battery back-up for easy install

The sensors use ambient room light – natural or lighting – with a battery back-up, making them super easy to install and very low maintenance.

Access real-time data locally or in the cloud

Temperature data can be sent securely to a local network or the cloud — via Ethernet, LTE (4G) or WiFi — using Pressac’s smart gateway.

If you’re looking to order sensors for a project or have regular requirements for sensors, please contact our friendly team to discuss pricing options.

We offer volume discounts and bespoke branding.
