Detects when contact is made or broken

Monnit’s Wireless Dry Contact Sensor detects when there is contact between the two wired end points. It can easily be integrated into existing switches or contact plates. When the sensor detects contact between the two end points, it will immediately turn on the RF radio and transmit the data to the wireless gateway and iMonnit Online Sensor Monitoring and Notification System, allowing the user to immediately receive an SMS text or email alert. The sensor can be configured to detect both closed and open loops alerting if contact is made or broken and alert on state changes.

Working in industrial environments with potentially explosive atmospheres can be highly hazardous. IECEx is the International Electrotechnical Commission (IEC) System for Certification to Standards Relating to Equipment for Use in Explosive Atmospheres. The IECEx System facilitates international trade in equipment and services used in hazardous areas to address the risk of fires or explosions from flammable gases or dust.


Safety First, Always

There’s a risk to workers in many industries prone to producing explosive atmospheres. When flammable gases, mist, vapors, or dust mix with air, explosive atmospheres occur, and the slightest spark can set them off. The dangers aren’t only prevalent in the petrochemical industry but also in manufacturing, pharmaceutical, food processing, power generation, construction, architectural woodworking, and more.

Monnit provides a growing IECEx-certified Internet of Things (IoT) product line with award-winning1 ALTA-ISX Wireless Sensors to work safely in hazardous industrial environments within potentially explosive atmospheres.

Monnit’s ISX Long-Range Wireless Sensors are IECEx-certified2 under code: Ex ib IIA T3 Gb. Essentially, the IECEx-certified sensors are used in IEC Zone 1 areas where explosive industrial atmospheres of IEC group IIA gases (propane or similar) may be present.
These ALTA-ISX Sensors are not only certified as intrinsically safe in explosive atmospheres of group IIA and hazardous Zone 1 environments, but they’re also:

  • Incapable of causing a spark or reaching a temperature (class T3) that could ignite an explosive atmosphere comprising a range of group IIA gases or dust
  • Able to be used in many industrial applications worldwide where combustible gases (group IIA) may be present in Zone 1 areas

Monnit Gateway Options

An integral component of any IoT network is the gateway. A gateway device allows for data from sensors to be transmitted to the iMonnit software platform.


Monnit Ethernet Wireless Gateway 4

Monnit’s Ethernet Gateways allow your Monnit Wireless Sensors to communicate with the iMonnit™ Online Wireless Sensor Monitoring and Notification System without the need for a PC. Simply provide power and plug the gateway into an open Ethernet network port with an internet connection. It will then automatically connect with our online servers, providing the perfect solution for commercial locations where there is an active internet connection.

Monnit 4G + Ethernet IoT Gateway

The ALTA® by Monnit Wireless IoT Gateway combines a 4G LTE CAT-M1/NB2 cellular engine and Ethernet platform with Monnit’s wireless access point network to aggregate and communicate data from Monnit ALTA Wireless Sensors. The ALTA IoT Gateway allows ALTA Sensors to operate on the world’s leading cellular networks and stay connected to the Internet. The gateway uses AC main power but also has redundant power through a battery backup lasting up to 60 hours.

To meet the global demand for enterprise IoT deployment, the IoT Gateway communicates with the cloud-based iMonnit® monitoring software via cellular transmission, making it ideal for remote locations or where the Internet isn’t available. The RJ-45 Ethernet jack allows local device configuration, diagnostics, and connectivity backup. The IoT Gateway is instrumental in sending sensor notifications via text, email, or call if user-defined conditions are met or exceeded.
