IMI TWTG

NEON Contact Sensor

Contact sensor for industrial applications, designed for fast, non-intrusive installation and continuous remote monitoring of asset position.

  • Tick

    Flexible mounting options allow quick, tool-free installation on a wide range of assets, enabling deployment in under two minutes without interrupting operations.

  • Tick

    LoRaWAN wireless connectivity provides secure, near real time position updates, ensuring reliable monitoring even in hazardous or hard-to-reach industrial environments.

  • Tick

    Built for demanding conditions with IP65 protection, ATEX/IECEx Zone 1 certification, and a battery life of up to 5 years, reducing maintenance needs and maximising uptime.

Knowing the position of assets in an industrial environment or having certainty about the correct placement of assets provides insight into operational metrics.

These crucial data points will ensure that safety and efficiency levels increase. Safety issues or incidents will be detected faster, sending help immediately when needed.

Based on magnetic field detection, the asset’s position information is provided by the NEON Contact Sensor and made remotely available within the application platform in near real time. When applied for a variety of use cases, these wireless devices can contribute to increased production efficiency and reliability of operational processes. NEON sensors are very user-friendly to be installed and maintained.

The sensor measures the presence of the magnet, and thus the asset, on a (frequent) time-based interval. When the sensor detects that the magnet is not present anymore, the sensor will send an alert message which can trigger alarms to operators. The NEON Contact Sensors, like all NEON products, comes in the reliable NEON form factor; battery-powered, IECEx / ATEX Zone 1 certified I-IoT device, communicating wirelessly via LoRaWAN.

IECEx / ATEX Zone 1 certified

Designed for industry from the very start, IMI TWTG NEON Contact Sensors are built to not only operate in industrial sites with dangers of explosive gasses being handled but also all other elements that a sensor may be exposed to in the course of its 10 year lifetime. It has been tested and certified to work in conditions from -40° to +80° Celsius without hampering performance. Additionally, the battery lifetime has a minimum operational period of up to 5 years, therefore, periodical maintenance can be kept at a minimum. An integrated device management layer enables service models, ensuring maintenance.

NEON Product Line – LoRa devices designed for heavy industry

The NEON product range supports all industrial customers moving towards LoRaWAN as the Industrial IoT network of the future. The LoRaWAN network gives industrial operations a secure solution, which has no vendor lock-in, scales up to tens of thousands of sensors, covers complete sites with only a small amount of gateways, and best of all – the low-power approach means that the lifetime of the NEON products can be extended dramatically. This international networking technology is quickly becoming the industry standard.

NEON stands for a standardized approach to collecting data points from within the operation and a general approach to creating integrated solutions with existing IT ecosystems.
