Automation and Controls
Enicstra carries a broad inventory of industrial automation and controls components used across discrete manufacturing, process plants, and machine OEM builds. The catalog spans sensors, PLCs and I/O, HMIs, servo and variable-frequency drives, motion control, safety devices, power supplies, connectors, and signal conditioning hardware. Where a current-generation part is no longer practical or available, we also locate obsolete and surplus units to keep older lines running without forced retrofits.
We source through a global supplier network rather than holding OEM franchises, which lets us cover legacy controllers, end-of-life drives, and discontinued sensor families alongside in-production catalog items. Every order ships from St. Louis after bench testing, and parts carry a 12-month functional warranty regardless of whether they were classified as new, surplus, or factory refurbished by the original maker.
If a specific automation part is not listed, send the OEM part number or a photo of the legacy nameplate and we'll quote sourcing options — most quotes are returned within 1–2 business days.
