Transmission Control
Electrovac has been producing hermetically sealed housings for transmission controls in automatic vehicles since the early 2000s.
Growing comfort demands and higher safety requirements are driving the global technology shift from manual transmissions to automatic transmissions. Automatic transmissions are not only more comfortable and safer, but also more fuel-efficient and dynamic than manual transmissions.
Electrovac manufactures high-tech transmission controls for the mobility industry with high automation and process reliability on specially developed production lines.
Our long-standing expertise and continuous developments support Electrovac’s zero-defect strategy.
Feedthroughs for Climate Compressors for E-Mobility
Electric climate compressors are used in electric and hybrid vehicles. These compressor applications must withstand moisture, extreme temperatures, and vibrations on a permanent basis.
Our hermetically sealed glass-to-metal feedthroughs for climate compressors ensure a long service life and thus provide long-term reliable cooling for environmentally friendly hybrid and electric vehicles.

Industry
Glass Feedthroughs for the Telecommunications Industry
- Transistor sockets are used in fiber optic applications as housings for receiver and transmitter assemblies.
- Hybrid and special housings are used to protect electronic circuits and components of receiver and transmitter modules.
- In addition, our feedthroughs are used in data communication, microwave technology, and high-speed data transmission.
Transistor Headers
Electrovac has over 60 years of expertise in transistor header manufacturing. Transistor housings or TO headers with standard dimensions were produced as mass products in the past to keep manufacturing costs as low as possible.
Depending on the sealing technology, various metal variants are used:
- As compression glass feedthrough: cold-rolled steel or stainless steel with NiFe pins or Kovar pins
- As matched glass feedthrough: Kovar or Alloy 42 with Kovar pins
The base plates or caps are manufactured in our own stamping production facility using stamping technology or deep-drawing technology. Transistor headers are nickel-plated and gold-plated according to customer requirements and further processing methods.
From small quantities to highly automated million-piece production, Electrovac supplies the following TO headers:
TO5
Design: shelled
Outside Dia in mm: 9.2
Plateau Dia in mm: 7.67
TO8
Design: stamped
Outside Dia in mm: 12.7
Plateau Dia in mm: 10.8
TO8
Design: stamped
Outside Dia in mm: 15.25
Plateau Dia in mm: 13.35
TO18
Design: shelled
Outside Dia in mm: 5.4
Plateau Dia in mm: 4.24
TO39
Design: stamped
Outside Dia in mm: 9.13
Plateau Dia in mm: 7.67
TO46
Design: stamped
Outside Dia in mm: 5.4
Plateau Dia in mm: 4.24
Upon customer request, Electrovac also supplies the corresponding TO caps together with the glass feedthroughs.
Due to the large number of existing transistor headers, we do not offer standard catalogs, but instead develop our production processes flexibly according to our customers’ requirements and design specifications.
Energy
Maximum reliability for long-lasting systems: Secure energy supply begins where standards end. For over 30 years, Electrovac has been providing the technological foundation for highly resistant battery solutions that remain absolutely reliable even under extreme conditions between -65°C and 150°C.
Our hermetic battery covers and feedthroughs are the core components for lithium-thionyl chloride and thermal batteries. With a service life of up to 25 years and a production capacity of 30 million units per year, we combine precision in detail with global scalability.

Battery Covers
Our battery covers have been used for lithium-thionyl chloride and thermal batteries for more than 30 years. These Li-SOCl2 batteries ensure optimal electronic power supply.
To withstand the aggressive materials of these applications and ensure long shelf life and device safety, Electrovac has developed processes for manufacturing high-quality battery covers with special glasses. These guarantee extremely low discharge and are used at temperatures from -65°C to 150°C. The service life of these quality products is up to 25 years.
We manufacture hermetic feedthroughs with steel and stainless steel covers in various sizes, such as: AA, C, D, DD, and many more. Whether in mass production of 30 million battery covers per year or in small quantities for special projects (e.g., for thermal batteries) – Electrovac stands for flexibility and quality.

Medical
Hermetic Housings for Medical Technology
Electrovac’s hermetic housings are frequently used in medical technology. Since medical devices are subject to high cleanliness requirements, the devices must be steam-sterilized in autoclaves at regular intervals under high pressure and extreme temperatures.
The components are exposed to enormous stresses, which is why special materials must be used. Our hermetic housings reliably protect the electronic components and ensure a long service life.
