Practical before clever
Automation operators actually trust.
We design and build application-specific controllers, boards, and kits in North Carolina. From air compressors and pumps to CNC coolant sumps and hardware development tools, our products cut energy use, shorten production time, and catch small problems before they turn into big failures.
What we manufacture
Every SAM product is built on the same conviction: a machine that can perceive its own condition runs better than one that can't. Not a relay panel. Not a fixed-setpoint timer. Adaptive feedback applied to the equipment that quietly carries the modern world.
Compressor Controllers
R100 single-pump and R200 duplex controllers. Drop-in replacements for pressure-switch and timer control.
Fluid systemsPump Controllers
Water, irrigation, and sewage pump control. IP67-rated, pre-wired.
CNC shopCNC & Coolant Monitoring
TrueLevel CNC: solid-state coolant level and temperature monitoring for machine sumps.
ComponentsSensors & Components
