What Jacob does

Jacob GmbH Elektrotechnische Fabrik is a German manufacturer founded in 1922, headquartered in Kernen (near Rommelshausen), Germany, specializing in cable entry systems (Kabeldurchführungssysteme) and cable glands (Kabelverschraubungen). The company offers over 6,000 products organized into proprietary product families including PERFECT, WADI, UNI Dicht, FAVORIT, and Clamping Jaw cable glands, available in brass/nickel-plated metal and plastic variants with options for EMC (electromagnetic compatibility) shielding and EX (explosion protection, ATEX-certified for Zone 1/21 and 2/22 hazardous areas). The portfolio extends to cable entry plates (KADP), cable entry strips (KADL), sealing grommets (KLIKSEAL), pressure equalization elements, Ex-junction boxes, Ex-LED lighting, and level measurement technology through the Jacob Sensors sub-brand. Jacob also distributes HAWKE, Burndy, and Killark products, and offers customized cable entry and explosion protection solutions.

The company serves a diversified set of industrial verticals including manufacturing, construction, automotive, automation, e-mobility, railway, solar energy, hydrogen (H2), wind (onshore/offshore), and LNG — addressing safety-critical applications where cable connections must withstand moisture, dust, mechanical stress, electromagnetic interference, and explosive atmospheres. Products comply with EN 62444, RoHS, REACH, and various international safety and environmental standards.

Jacob's go-to-market combines direct sales through its ecommerce-enabled company website (jacob-gmbh.de) with channel partnerships, notably Fabory, a fastener distributor operating across 10 European countries. The company is privately held under German Mittelstand ownership, with Mr. Bernd Bohl serving as General Manager. Revenue, headcount growth rate, and pricing are not publicly disclosed; the firm operates with 11-50 employees and pursues expansion through sub-brand distribution, energy-vertical product development, and broader European channel reach.
