About ODU
ODU GmbH & Co. KG, headquartered in Mühldorf am Inn, is an internationally active manufacturer of connector systems for the reliable transmission of power, signals and data. The product portfolio includes circular connectors, modular connectors, electrical contacts, cable assembly, fiber optic solutions and customized system solutions. With an in-house manufacturing depth of 80 percent, ODU develops and produces everything from the contact to the housing to the complete assembly in-house, supported by its own laboratory and testing capacities for EMC, high voltage and partial discharge measurement. Known technologies include Springwire, Lamella and Slotted contact technology as well as silicone overmolding (LSR/HCR) for medical applications. The systems are used in medical technology, test and measurement, military and security technology, industrial, robotics and automotive, often under harsh environmental conditions. The family-owned company was founded in 1942 by Otto Dunkel, generates around 317 million euros in revenue and employs 2,800 people worldwide, of whom 1,500 are at the main site in Mühldorf am Inn.

Materials and Processes
Gold Plating of Contacts
Standard plating for electrical contacts ensuring constant contact resistance and high mating cycle counts.
Silver Plating of Contacts
Alternative standard plating for contacts; further platings available on request.
Liquid Silicone Rubber
Liquid silicone for overmolding of medical system solutions, suitable for up to 500 autoclave cycles.
High Consistency Rubber
Solid silicone rubber for robust cable protection and durable adhesion in overmolding.
Ceramic Ferrules
Classic ceramic ferrules as the basis of physical contact fiber optic technology.
Plastic and Metal Housings
Housing materials for connectors depending on the application, e.g. lightweight and non-magnetic or robust for harsh environments.
