With roots back to 1983, Conesys is an ISO 9001 and AS9100-certified vertically integrated provider of circular connectors. With connector manufacturing facilities in Torrance, California, US, and Toulouse, France, Conesys provides a wide range of interconnect products, including a broad offering of military specification connectors.

Long known as a leader in the military/aerospace connector world, Conesys is now taking its strengths — world-class vertically integrated design and manufacturing, uncompromising quality, commitment to customer satisfaction, and entrepreneurial flexibility — to the demanding railway market.

Reverse-bayonet railway connectors

Through its J-Tech brand, Conesys provides its JTCIR product line of reverse-bayonet electrical connectors, which are tested to and comply with the specifications of VG95234. Conesys connectors are interchangeable, inter-mountable and inter-mateable with connectors from other manufacturers.

Available in aluminum or stainless steel and a variety of platings, contact styles and rear accessories (backshells), Conesys is the only manufacturer to offer as standard flame-retardant inserts tested in the UL94V0 flammability test (competitors charge a healthy premium for this).

JTCIR reverse-bayonet rail connectors offer unsurpassed performance and durability, and intermate and intermount with VG95234 connectors from other manufacturers.
Rugged RJ-45 and rugged USB connectors offer the railway system designer a data acquisition and transmission connector option with unparalleled performance in harsh environments.
Conesys operates a 120,000ft² (11,148m²) CNC rail machining center at its Torrance, California, US campus, with the capacity to manufacture one million connector shells per month.

Rugged rail RJ-45 and USB connectors

Placing a commercial RJ-45 or USB connector inside a metal shell doesn’t make it rugged. For pristine data acquisition and transmission in the harshest environments, Conesys has designed its rugged RJ-45 and rugged USB connectors for those applications where ‘rugged really means rugged.’

Compare Conesys’ performance specifications and test methods against any competitor’s for temperature range and cycling, sealing, shock, vibration, durability and corrosion resistance and you will see that Conesys delivers what some others only promise.

Custom rail circular connectors

With in-house design, manufacturing and testing, Conesys can turn your special interconnect requirements into a final product, and do it to your schedule. We offer the cost-effectiveness and control of total vertical integration in one location, including engineering and design, machining, rubber and plastic molding, plating, assembly and testing. Our special connectors and accessories include:

  • Special metal shell design, material and plating
  • Integrated rear accessory for over-molding (no separate backshell required)
  • Special insert arrangements
  • Alternate contacts, including PC-tail and compliant pin (press fit)
  • High-speed RF contacts, including Quadrax contacts

EMI and transient-voltage suppression rail connectors

The EMP Connectors division of Conesys has provided advanced transient suppression and EMI filter connectors for both military and commercial applications since 1987. It specializes in custom-built, high-powered designs within compact connector envelopes to fit your power handling, clamping voltage and package requirements, often at a significant cost-saving over the typical board-mounted configurations.

Specializing in the science of electromagnetic compatibility (EMC), EMP Connectors is in the unique position of being able to supply both EMI filtering and EMP transient surge protection in the same compact connector package. By incorporating both types of protection into this single device, they have developed a proven solution that saves both space and cost when compared to traditional protection methods.
