What Senitec does

Senitec, Inc. is a privately held U.S. industrial manufacturer founded in 2001 and headquartered at 2150 Boggs Road, Suite 410, Duluth, Georgia. The company designs, manufactures, and sells valve position indicating devices (VPIDs), limit switch boxes, proximity sensors, inductive sensors, and integrated solenoid pilot valve switches for process industries. Its core product portfolio comprises five series (A Series in copolyester, B and D Series in aluminum with epoxy coating, C Series in stainless steel, and L Series in explosion-proof die-cast aluminum) plus the Shadow inductive sensor line, with enclosure ratings spanning NEMA 3, 4, 4X, 7, and 9 and certifications including ATEX, EEx, CSA, NEC 505, and IP67 for hazardous-area applications.

Technically, Senitec's products integrate mechanical switches, magnet and proximity inductive sensors, hermetically-sealed solid-state sensors, and AS-Interface (AS-i) networking modules compliant with version 2.1 protocol. Proprietary engineering includes the Set and Forget cam design, which uses an internal leaf-spring mechanism to lock onto a splined shaft without screws or springs, eliminating calibration drift over the product lifecycle. The company manufactures at its Duluth, Georgia facility and employs 1-10 people.

Senitec operates a direct B2B field-sales model, selling hardware products to enterprise industrial customers in oil and gas, chemical processing, mining, marine, food and beverage, and pharmaceutical sectors. Pricing is not publicly disclosed; customers engage via website contact form, phone, or fax to request quotes. Revenue is generated through one-time hardware sales with associated replacement parts and accessories. The company claims a global footprint enabled by international hazardous-area certifications, though its primary operating geography is the United States. No revenue figures, funding history, or ownership details are publicly disclosed.

Revenue model

1. Industrial Valve Position Indicators and Switches: SeniTec generates revenue through the sale of industrial valve position indicating devices (VPIDs), limit switches, proximity sensors, and related components. Products are sold as standalone hardware with various switch configurations (mechanical, inductive, SPDT, DPDT) and enclosure options (NEMA 3, 4, 4X, 7, 9). Revenue is primarily one-time hardware sales with potential for replacement parts and accessories.

Core offering

Senitec designs, manufactures, and sells industrial valve position indicating devices (VPIDs) and process control accessories from its Duluth, Georgia facility. The portfolio centers on five limit switch box series (A, B, C, D, L) offered in plastic, aluminum, and stainless steel enclosures rated NEMA 3/4/4X/7/9 and ATEX/CSA explosion-proof, paired with Shadow solid-state inductive sensors, AS-Interface networking modules, integrated solenoid pilot valve switches, and configurable switches, indicators, and NAMUR mounting options.

Product overview

SeniTec is an industrial manufacturer of valve position indicating devices (VPIDs) and process control solutions. The product portfolio centers on five core limit switch box series—A Series (plastic/copolyester anti-corrosion), B Series (aluminum compact/economical), C Series (stainless steel), D Series (aluminum with epoxy coating), and L Series (explosion-proof for hazardous areas)—each offered in NEMA 3, 4, 4X, 7, and 9 rated enclosures. These core products integrate a range of modular accessories including Switch Options (mechanical, inductive, proximity switches), Indicators (visual position displays), and Mounting Options (NAMUR standard brackets). Advanced connectivity is provided through AS-Interface (AS-i) networking modules, and specialty offerings include Shadow Inductive Sensors for solid-state sensing and an Integrated Solenoid Pilot Valve Switch combining solenoid control with position monitoring. The company also provides proprietary Set and Forget Cam Design technology for calibration-free operation.
