What Douglas Electrical Components does

Douglas Electrical Components is a privately held, Randolph, New Jersey-based manufacturer of precision-engineered hermetic electrical feedthroughs and connectors serving mission-critical applications in aerospace and defense, semiconductor equipment, oil and gas (hazardous locations), medical equipment, space simulation, and other high-technology industries. Founded in 1944 as Douglas Engineering Company, the firm pioneered the industry's first epoxy-based wire feedthrough in 1975 and reoriented entirely around hermetic sealing technology under its current name. Today it operates a U.S. manufacturing headquarters plus a wholly-owned European sales and support entity (DEC Europe GmbH) in Ratingen, Germany, with a workforce in the 101–250 range.

The company's product platform is built on a proprietary low-outgassing epoxy sealing technology certified per NASA ASTM E-595-93 (0.33% TML, 0.00% CVCM), capable of encapsulating conductors from 38 AWG to 500 MCM, up to 3,200 conductors per feedthrough, and validated across vacuum to 15,000 psi pressure and -200°F to +350°F temperature. Branded product lines include PotCon® hermetic bulkhead connectors, DuctorSeal® and JacketSeal™ wire and cable feedthroughs, OptiSeal™ fiber optic feedthroughs, CircuitSeal™ for PCB encapsulation, StudSeal™ terminal seals, and PortPlate™ custom flange assemblies, supplemented by a broad catalog of D-sub, Micro-D, MIL-DTL-38999, coaxial, M8/M12/M23, USB, KF, Conflat, NPT, and underwater hermetic connectors. The 2022 acquisition of Electronic Products, Inc. (EPI) added complementary HTCC ceramic feedthrough and glass-to-metal seal capabilities for microelectronic packages.

Douglas generates revenue via direct enterprise sales supported by technical sales engineers who provide application consultation, custom design, prototyping, and qualification services, with quote-based pricing on engineered-to-spec products and a standard catalog of pre-configured feedthroughs available at 4–6 week lead times (expeditable to 1 week). Pricing is one-time/perpetual for both custom and standard products, supplemented by value-added assembly and harness services that are billed under multi-year agreements. Customers span thirteen addressable verticals, with aerospace and defense, hazardous locations/oil and gas, and semiconductor equipment treated as primary segments; revenue concentration is not publicly disclosed and the customer mix skews toward long-lifecycle OEM programs where products are designed-in and requalification cycles discourage switching. The firm maintains ISO 9001:2015, ISO 14001:2015, ITAR-DDTC, AS9102, IPC/WHMA-A-620, NASA ASTM E-595, UL 984/1203/674/94HB, and MIL-STD-810 certifications and runs a 100% electrical and mechanical test regimen on all assemblies.

Core offering

Douglas Electrical Components designs and manufactures custom and standard hermetic electrical feedthroughs, connectors, and cable/connector assemblies that pass electrical signals, power, or fiber optics through pressure or vacuum boundaries without leakage. The company uses a proprietary low-outgassing epoxy sealing technology (NASA ASTM E-595 certified) and complements it with HTCC ceramic and glass-to-metal seals acquired from Electronic Products Inc. (EPI). Products are engineered for mission-critical applications in aerospace, defense, semiconductor, oil and gas, medical, and other high-technology industries, with operational envelopes spanning ultra-high vacuum to 15,000 psi and -200°F to +350°F.

Product overview

Douglas Electrical Components is a manufacturer of precision-engineered hermetic electrical feedthroughs and connectors, built on proprietary epoxy-based sealing technology pioneered in 1975.
