What Cr Magnetics does

CR Magnetics, Inc. is a privately held, St. Louis-based electronic manufacturing company founded in 1986 and currently operating as a wholly owned subsidiary of Khorporate Holdings, Inc. The firm designs and manufactures a comprehensive catalog of electrical monitoring sensors, transducers, and components organized into seven product families: analog transducers (77 SKUs spanning voltage, current, power, and frequency monitoring with 0–5VDC, 0–10VDC, and 4–20mADC proportional outputs), RS485/MODBUS digital transducers (9 SKUs), relays/switches/sensors (16 SKUs including ground fault and current sensing relays), indicators and displays (8 SKUs), AC current transformers (63 SKUs including ANSI metering class, commercial, ground fault, and specialty types), zero sequence current transformers (9 SKUs), and custom-engineered solutions. Underlying technologies include True RMS sensing for non-sinusoidal waveforms, toroidal current transformer architectures for non-intrusive monitoring, zero-sequence CT designs for ground fault detection, and in-house rubber mold/laser cutter/UV printer capabilities for rapid customization.

The business operates a hardware unit-sales revenue model with catalog pricing ranging from $8.27 (entry-level 5A secondary current transformers) to $764 (multi-element digital transducers), supplemented by quote-based custom solutions. Go-to-market combines direct factory sales (phone, email, online quote form) for custom and large orders with a multi-tier distribution network — flagship stocking partners Digi-Key and McMaster-Carr, broad US regional distributors (Motion Industries, Wesco, Graybar, Grainger, CED), and international partners in 14+ countries spanning North America, Europe, APAC, Middle East, and South America. The company holds ISO 9001:2015, UL US/Canada, CE, CSA, and RoHS certifications on most popular products, and operates a 40,000 square foot manufacturing and warehouse facility staffed by 11–50 employees with engineering expertise in electrical monitoring and power measurement. Primary customer segments are industrial/equipment engineers, OEM manufacturers, electrical contractors and distributors, and safety-critical application integrators.
