What Erma Tech Harnesses & Hoses does

Erma Tech Harnesses & Hoses is a São José dos Campos, Brazil-based AS9100D:2016 and ISO 9001:2015 certified manufacturer specializing in the design, assembly, fabrication, installation, and maintenance of high-reliability electrical wiring harnesses, cabling, test interfaces, and hydraulic/pneumatic devices. The company serves tier-1 aerospace and defense OEMs including Embraer, Airbus, AVIBRAS, ATR, RADA Electronic Industries, Thales Alenia Space, ALSTOM, and DCNS/STX, with documented programs spanning the EMB-145, EMB-190, EMB-314, Phenom 100/300, KC-390, Super Tucano BATD, AF-1/AF-1A Skyhawk, A350, A380, ATR 72-500, ASTOS defense munitions, Scorpène and Barracuda naval projects, and Citadis/RGV railway programs. The firm was formed in 2016 through the merger of French ERMA Electronique (Grupo Charbonnier) and Brazilian Troya Tech (founded 2003), and operates from a 1,000 sqm headquarters in Brazil's largest aerospace cluster, near Embraer, ITA/DCTA, and INPE.

The company's core technology stack centers on deterministic industrial automation rather than AI: automatic wire cutting and stripping machines meeting aerospace standards, automatic electrical wiring test benches with continuity/isolation reporting, 2D form board and 3D routing design, and proprietary hydraulic/pneumatic tooling for hose, clamp, sealing, fuel, and hydraulic testing. It maintains 230 approved Part Numbers for defense vehicle wiring harnesses and has produced approximately 10,000 vehicle harnesses since 2016 for the AVIBRAS ASTOS program, with 100% production tested under certified protocols.

Erma Tech operates a project-based B2B enterprise field-sales model with no public pricing, no e-commerce channel, and no resellers. Revenue is generated through one-time custom manufacturing contracts, on-site installation and maintenance services, managed labor-allocation work packages (25-180 technicians deployed per major program), and bespoke technical training. The company is privately held by French diversified conglomerate Grupo Charbonnier, with no external institutional investors, no public listing, and no disclosed revenue or funding history. Customer engagement is direct, multilingual (Portuguese, English, French), and centered on long-tenured qualified-supplier relationships within Brazilian and select international aerospace and defense programs.

Regional players

• AeroVironment: US-based aerospace and defense technology company. Less direct overlap in wiring harnesses specifically, but operates in adjacent aerospace electrical and defense systems space.
• AEL Sistemas: Brazilian defense electronics company (subsidiary of AEL Sistemas/Elbit Systems). Same geographic and end-market context as ERMA TECH in Brazilian aerospace/defense, providing a regional benchmark for Brazilian defense supplier scale.

Broad incumbents

• TE Connectivity: Global leader in connectors, sensors, and aerospace wiring components. Both a strategic partner (ERMA's AVIBRAS program collaborator) and a potential competitor/alternative-supplier for OEM wiring harness programs.
• Amphenol: Global manufacturer of interconnect, antenna, and sensor solutions serving aerospace and defense. Overlaps with ERMA in electrical interconnect components and wiring solutions across aerospace and defense verticals.
• GKN Aerospace: Global Tier-1 aerospace supplier (Melrose portfolio) with wiring and electrical interconnect capabilities. Competes broadly in aerospace electrical integration and represents the type of large incumbent ERMA could either partner with or lose share to.
• Safran Electrical & Power: Division of Safran focused on aircraft electrical systems, wiring, and power generation. Competes with ERMA in aerospace electrical integration and serves as a benchmark for scale, certification, and global footprint in aerospace electrical.
• Eaton Aerospace: Diversified industrial manufacturer with significant aerospace fuel, hydraulic, and electrical systems. Comparable in aerospace electrical and hydraulic/pneumatic components (overlapping with ERMA's hydraulic/pneumatic device line).

Direct peers

• Carlisle Interconnect Technologies: Specialized manufacturer of aerospace/defense interconnect solutions including wiring harnesses, cables, and connectors. Directly comparable business model and end-market exposure to ERMA, though at significantly greater scale.
• Latécoère: French Tier-1 aerospace wiring harness and aerostructures manufacturer. Directly competes with ERMA TECH in aerospace wiring harnesses, with significant Airbus relationships - making it the closest global peer for ERMA's core business.
• InterConnect Wiring (Latécoère subsidiary): Acquired by Latécoère, focused exclusively on aerospace wiring harness manufacturing for military and commercial platforms. Closest pure-play peer to ERMA's core wiring harness manufacturing business.
