What Tri-Tronics does

Tri-Tronics Co. Inc. is a privately held, family-owned manufacturer of industrial sensing and elevator safety products headquartered in a 28,000 sq. ft. assembly facility in Tampa, Florida. Founded in 1954 by three former Motorola engineers and led since 1974 by the Ahlswede family, the company has operated continuously for 71 years and assembles 100% of its products in the United States. Its portfolio is organized into three lines: industrial sensors (photoelectric, fiber optic, label/fork, registration mark, color and luminescence, clear object, and laser measurement), Photocraft rotary encoders (shaft, hollow shaft, wheel, absolute, and BlueCoder blue-light phased array encoders), and elevator door protection systems (3D Fusion, InvisiGuard, LEADINGEDGE, ElevatorEye).

The company's technology stack centers on optical and electronic sensing: microsecond response times on fiber optic amplifiers, blue-light phased array encoding for high-resolution rotary feedback, and 3D Time-of-Flight fusion with 2D light curtains for elevator door intelligence. Differentiated products carry compliance certifications including ASME A17.1-2019/CSA B44-19, EN 81-70, EN 81-20, ADA, IP65/IP67, and CE marking under EMC Directive EN 61326. The company holds multiple registered trademarks (BlueCoder, 3D Fusion, InvisiGuard, LEADINGEDGE, ElevatorEye, Photocraft, RetroSmart, SmarTEYE) and offers product customization and private labeling.

Tri-Tronics monetizes through hardware unit sales distributed via a global authorized distributor network, a direct B2B e-commerce storefront at ttco.com, and direct technical sales for custom encoder solutions. Customer segments are industrial automation (packaging, material handling, manufacturing, robotics) and the elevator industry (hospitals, universities, public housing, airports). Pricing is not publicly disclosed for most products; sensor accessories are listed at $3.87-$1,503 per unit, and some elevator products (InvisiGuard) are restricted to phone or purchase order transactions. The company has not raised external capital and remains under Ahlswede family ownership, with Priscilla Ahlswede as president.

Revenue model

1. Industrial Sensor Hardware Sales: Tri-Tronics generates revenue primarily through the sale of photoelectric sensors, fiber optic sensors and amplifiers, ultrasonic sensors, and measurement sensors. Products are sold as standalone hardware units with individual pricing for sensors, accessories, and components.
2. Rotary Encoder Hardware Sales: Revenue generated from the sale of incremental and absolute rotary encoders including shaft encoders, hollow shaft encoders, wheel encoders, and associated accessories such as measuring wheels, shaft couplings, mounting brackets, and custom cable assemblies.
3. Elevator Door Protection Systems: Sale of elevator door protection products including light curtains (3D Fusion, InvisiGuard, LeadingEDGE), photo-eye systems (ElevatorEye), and associated power supplies and mounting hardware. Some products (e.g., InvisiGuard) require phone/purchase order orders rather than direct online purchase.
