About Us
We make what we sell.

We design. We produce. We are a
product engineering and
manufacturing company. And our products are made in the same building in which we design them. That means that we have the benefit of addressing design and manufacturing issues with all of our resources combined – and that we are able to communicate with each other face-to-face. That helps to ensure that our products are of the
highest quality and workmanship.
Unique application? Bring it on!

We are known for our capabilities in
solving performance problems by designing customized products that work in challenging environments. Our senior salespeople are all engineers and our engineering staff outnumbers any other discipline in our company. During our product development process, we test our concepts thoroughly to ensure that our solutions work. We know what we are doing.
We are a contemporary, integrated manufacturer.
Our strength as a manufacturer is based on five key factors:
- We have assembly operations, machine shop operations and testing operations all under one roof.
- Our products are produced to ISO 9001:2008 standards.
- Proprietary, state-of-the-art software drives our processes.
- Continuous investments are made in new equipment and machinery
- Our manufacturing personnel are experienced and conscientious.
One-stop shopping for temperature sensor assemblies.

Conax Technologies is the
only company that designs and manufactures the complete range of
temperature sensor products and related sealing feedthrough solutions that you require. So if you need a single source of supply, we are ready, willing and able.
We’ve produced over 1,000,000 part numbers over the last ten years.

Over the last ten years, Conax has manufactured over 450,000
temperature sensor part numbers and over 700,000
compression seal fitting part numbers, many of which could be ordered directly from
our catalogs. Imagine how many we have made over our entire 60 year history! We are quite certain that puts us in a class of our own relative to the diversity of experience that we can bring to your company.
Our return department is a part timer who worked 31 hours last year.

Only 0.2% of our products were returned in 2010 for a handful of reasons. One of our largest customers has ordered over 30,000 sensors over the years – only 5 have been returned (the screws were loose and we tightened and sent back). We know how to make
high quality products.
We produce order sizes from 1 to 100,000 units.

We understand the demands of customers who require only one item as well as those customers who require thousands of items. And our state-of-the-art 45,000 square foot lean
assembly line and
machine shop has been designed to do this without special scheduling. No matter what size of the order, we can make it. Because the world works that way, so do we.
240 wires? 30,000 psi (2067 bars)? We have sealing solutions.

Our compression seal fittings use our exclusive ‘
soft sealant’ technologies that can be designed to seal pressures ranging from vacuum up to 30,000 psi (2067 bars) involving temperatures ranging from -400°F to 3000°F ( -240°C to +1650°C).
Replaceable sealants permit repeated use of stainless steel fittings for easy installation and service in the field. When high density feedthroughs are required, our MHM feedthroughs fit the bill in sealing up to 240 conductors or 120 thermocouple pairs.
4200°F? 2300°C? No sweat.
Our high temperature thermocouples are specifically designed for durability and reliability in high temperature applications to 4200°F (2315°C). Such
applications generally involve oxidizing, reducing or inert gas environments that challenge the life of the thermocouple. We bring more than 60 years of experience in temperature sensor design to maximize the life and reliability of thermocouples in these environments.

We never give up when addressing
design challenges. We never give up until you’re satisfied with the outcome. Most importantly, we never give up trying to improve ourselves and the products we make.
