Ex Proximity System

Ex | Solutions for Hazardous Areas and Beyond

HIT-NOT®-Ex is engineered for industries using mobile equipment, like warehousing, manufacturing, and others where equipment and pedestrians work in close proximity that require hazardous area certification for potentially explosive environments.

Unlike other RF technologies, HIT-NOT® reads and warns through walls, racks, containers and other blind corner obstructions with audible and visual alerts to both the equipment driver and the pedestrian. The detection zones are stable even in heavy metal environments such as oil platforms, refineries, or chemical plants, where RF systems are prone to multi-path and reflections.

Our Ex series, a first in materials handling, providing reliable and precise proximity systems to be used in hazardous areas with certified equipment requirements.

HIT-NOT®-Ex is  Approved for: IECEx IIB T6 Gb

  • Take advantage of the Exceptional and Expandable HIT-NOT® technology, adding the fully compatible HIT-NOT®-Ex system to cover hazardous areas, while working seamlessly with the standard HIT-NOT® Systems already deployed in your facility.

  • The only Proximity Detection System on the Market that covers the Entire Facility!

  • No need to install multiple systems on the vehicles or to swap pedestrian devices when traveling between fresh air and hazardous areas. 

What experience does the HIT-NOT® team have in Ex environments?

  • HIT-NOT® has led the way in the development of proximity detection systems for materials handling. It’s Patented Technology was originally developed as HazardAvert® for the underground mining industry, a harsh hazardous environment.
  • HazardAvert® was the First Proximity Detection System to complete a mandatory field trial in 2005, conducted by the Mine Safety and Health Administration (MSHA), resulting in the first approved proximity system. HazardAvert® is being used throughout the world in mining applications today. HazardAvert® also has IECEx Certification.
  • Both have been saving lives and preventing injuries for years. Over 40,000 HIT-NOT® units have been deployed globally in many industries!
  • Prior to HazardAvert®, FEP developed and manufactured ruggedized Gamma Radiation Detectors for downhole oil and gas drilling, among other applications, including IECEx approved systems.

  • Provides both Collision Avoidance (Vehicle to Vehicle Alerts) as well as Pedestrian Detection (Vehicle to Pedestrian Alerts) Detection Distances are user adjustable. 

What happens if I go into a non-Ex area of the facility with my HIT-NOT®-Ex Equipment?

  • Your HIT-NOT®-Ex PAD responds to standard HIT-NOT® Systems exactly the same.
  • If you drive an Ex equipped truck into a non-Ex area, workers and other vehicles in that part of the facility will receive alerts from your vehicle, exactly as from standard HIT-NOT® equipped trucks.
  • The HIT-NOT® Remote Event Monitor (REM) RELAY installed in a non-Ex area will collect and transfer data from the Ex truck to the cloud when the truck travels by the RELAY.The end-user will have 24/7 dashboard access to proximity and operational information.
