Lesman Instrument Company

What Lesman Instrument Company does

Lesman Instrument Company is an industrial-automation distributor operating as part of the Kele Industrial Automation Group. From its headquarters in Bensenville, Illinois, the firm functions as an authorized reseller of process and factory automation instrumentation for end users in chemical, pharmaceutical, oil and gas, power generation, water treatment, and discrete manufacturing. Its go-to-market is delivered through four wholly-owned divisions — Lesman, A-Tech Inc., AC Controls, and Ponton Industries — plus an additional RAECO DBA, with regional coverage spanning the U.S. Midwest and Pacific Northwest.

The product portfolio spans nine primary categories: level instrumentation; controllers and programmers (PLCs, RTUs, DCS); pressure instruments; process valves and regulators; solenoid valves; gas detection and monitoring; sensors (photoelectric, proximity, temperature, pressure, flow, encoders, LiDAR); industrial networking equipment (Ethernet switches, industrial PCs, I/O modules); and power products (AC-DC and DC-DC supplies, power protection). Distribution rights cover at least 16 premium automation brands, including ASCO, Banner Engineering, Honeywell Process Solutions, Siemens, WIKA, WAGO, Watlow, SICK, United Electric Controls, DeZurik, Jordan Valve, Panametrics (Baker Hughes), PULS Power, Red Lion Controls, Turck, and DwyerOmega. The company layers services on top of product distribution: instrument assemblies and seal-repair work, valve automation (60+ years of in-house expertise), a UL508A-certified panel fabrication shop (30+ years of experience), control-systems engineering covering DCS/PLC/RTU/SCADA migrations, on-site field services, and a free, registration-free training library of 160+ hours of video.

Revenue is generated primarily through quote-based hardware sales supplemented by professional services and a recurring Subscribe and Save program (5% on scheduled consumable shipments). Pricing is predominantly quote-driven with some disclosed unit prices (e.g., WAGO 2587 Power Supply from $40; PULS power supplies from $85 to $1,125; Honeywell 900P01-0501 60W Power Supply at $1,255.41) and free UPS Ground shipping on website orders of $750 or more. The sales motion is sales-led, with factory-trained specialists (16-year average instrumentation experience, including degreed engineers) reachable by phone, email, live chat, and direct website ordering. The firm is privately held with no disclosed funding rounds, no M&A activity in the input, and 11-50 employees.

Direct peers

• Ibex Engineering: Regional industrial automation distributor representing brands such as Yaskawa, ABB, and Parker across the Western U.S. Overlaps with Lesman's process and factory automation focus and serves similar engineer/buyer personas.
• AutomationDirect: Direct-to-customer industrial automation retailer selling PLCs, sensors, drives, and control components online. Closely matches Lesman's catalog breadth and sales-led distribution motion, with a stronger direct-from-manufacturer cost structure and larger digital footprint.
• Radwell International: Distributor of new and surplus industrial automation, controls, and MRO parts serving plant maintenance and production customers across the U.S. Comparable to Lesman in customer base, product breadth, and value-added repair/services offerings.
• AWC Inc. U.S. value-added distributor of industrial automation, motion control, and process instrumentation with engineering services and panel build capabilities. Highly comparable to Lesman in combining authorized distribution with technical services and project-based solutions.

Broad incumbents

• Allied Electronics & Automation (RS Components): Global catalog distributor of industrial and automation products under the RS Group, with deep North American coverage. Competes with Lesman across PLCs, sensors, and controls, but at much larger scale and broader product set.
• McMaster-Carr: Iconic U.S. industrial supply catalog with strong process instrumentation and controls offering, famous for same-day shipping and digital catalog UX. Comparable to Lesman on e-commerce velocity and customer experience, but a far broader mechanical and MRO supplier.
• W.W. Grainger: Broad-line industrial MRO distributor with significant process instrumentation and controls exposure through its KeepStock and Grainger Canada platforms. Competes with Lesman for plant maintenance spend but serves a far broader product taxonomy.
• Mouser Electronics: Global authorized distributor of semiconductors and electronic components with expanding industrial sensor and automation lines. Comparable buyer persona (design and maintenance engineers) and authorized-distribution model, though Mouser skews to electronic components rather than process instrumentation.
• Digi-Key Electronics: Global high-volume electronic components distributor with a growing industrial automation catalog. Overlaps with Lesman on sensors, power, and connectivity SKUs and competes for engineering buyers, though its core franchise is semiconductors and passives.
• Newark / element14: Premier Farnell-owned catalog distributor selling automation, test, and industrial components globally. Overlaps with Lesman on sensors, PLCs, and power products and shares an engineer-focused sales motion, but operates at significantly larger scale and geographic breadth.
