Diablo Controls is a leader in the traffic and access control industry. For over 40 years, they have pioneered the most important innovations in the history of the traffic control industry. In fact, they changed the entire course of traffic control electronics by introducing the first microcontrollers to the traffic and parking industries.


  • microprocessor NEMA controller
  • microcontroller safety monitor
  • digital period-measurement vehicle detector
  • liquid crystal display traffic controller
  • multi-tasking based central traffic control master

Their remarkable team has more inductive loop and Mini-vehicle detectors currently operating to their credit than any other group in the world. Additional innovations include anti-coincidence, Automatic Vehicle Identification (AVI), and Directional logic equipment.
Diablo Controls builds simple, easy to install, yet highly reliable, micro detectors, plug in detectors, loop and probe kits. We have the solar friendly detector, switchless detector or traditional detector you need.

Their access products are used to detect the presence of vehicles for access control, which includes gate access, door access, security, fence access and many other applications.
Diablo Controls builds innovative vehicle detection equipment for today’s complex traffic infrastructure. Their dual channel, four channel and shelf mount detectors are designed to handle both State of California (Cal-Trans) and NEMA applications. Their detectors are virtually maintenance free, easy to install, and designed to reliably transmit real-time data for a variety of traffic management applications. Diablo Controls designs, develops, and produces reliable parking control products such as micro detectors, plug in detectors, loop and probe kits.  Their products ensure accurate vehicle detection and count and reduce tailgating. Engineered to be used in entrance loops, safety loops, or free exit loops, their detectors are the only parking detectors you will ever need.
