What EI Sales does
EI Sales is a privately held electronic manufacturer's representative firm and vertically integrated contract manufacturer founded around 1984-1985 and headquartered at 69 Power Drive, Mankato, Minnesota. The company operates a 300+ person field sales and inside sales organization covering 11 Central US states (MN, IA, ND, SD, WI, MO, KS, NE, TX, LA, AR, OK) through five offices, acting as the sales and marketing arm for 20+ complementary manufacturer principals including E-Switch, Kingbright, Kyocera, Delta, Multicircuits, Cincon Electronics, Jauch Quartz, KATO Cable, Fair Rite, InterFET, and Shindengen America. EI Sales also wholly owns EI Sensor Technologies, an OEM sub-brand producing NTC, PTC, and RTD temperature sensors and custom probe assemblies.
The firm's manufacturing services span US-made quick-turn PCB assembly (4 to 24+ layers, IPC-6012 Class 3, MIL-PRF-31032), wire harness and cable assembly, custom lithium-ion and lithium-polymer battery manufacturing, conformal coating and selective masking, PCB overmolding, vapor phase soldering, mechanical manufacturing, and PCB design services with 24-hour prototype turnaround. These capabilities are qualified to ISO 9001, ISO 13485, AS9100, ITAR, RoHS, and REACH standards, supporting medical device, aerospace and defense, industrial automation, and heavy vehicle/off-highway OEM programs.
EI Sales generates revenue through two streams: commissions earned on electronic component sales sourced through its manufacturer principals, and contract manufacturing services billed to OEM customers for assemblies, harnesses, and sensors. Pricing is quote-based and negotiated per OEM program on multi-year contract cadence, with no public pricing disclosure. Customers are enterprise OEMs in four primary verticals (medical devices, aerospace and defense, industrial automation, heavy vehicle and off-highway) and secondary verticals (automation and robotics, outdoor and harsh-environment electronics), reached through a combination of direct field sales, inside sales support, the eisales.com website, industry events, and engineering training webinars.
