Custom Electronic Controllers

With over 175 years of combined experience our engineers have seen and designed a large variety of custom electronics. We’ve developed technology in use in many different fields including but not limited to:

Medical (Root Canal Controller, Ultrasonic Teeth Cleaner, Gurney Controls, and Patient Lifts)
Car Wash Controllers
Freight Elevator Door Controllers
LED Lighting controllers for both Emergency and Non-Emergency vehicles
Networking Controllers (including CANBUS, MODBUS, Ethernet, WiFi and Bluetooth®)
Industrial Control Systems (Compressor Controllers, Actuator Controllers, Grounding Systems, Custom IO boards).
Defense
Energy
Chemical
Water and Waste Water
Oil & Gas

Not only do we work with you to design a controller that fits your needs and budget, we have the ability to develop the software for it as well as manufacture it on site in the heart of the US for easy shipping anywhere. So let US know how we can help you!
