Cinch specializes in providing specialty interconnect and system solutions to the Military and Defense Market. We provide custom solutions with our creative, hands on engineering and end to end approach.

Fiber Optic Connectivity Solutions
Cinch EBOSA™ Expanded Beam Technology

Expands and collimates the optical beam up to 2000 times (single-mode) the original beam size making airborne dirt nearly benign to beam continuity and integrity.

Our patented active alignment technology aligns a standard LC ferrule to Cinch’s EBOSA™ with ultra-high precision. This results in insertion loss and reflectance performance that meets the MIL-DTL-83526/20 & /21 specification and can exceed the specification for customer specific applications for expanded beam connectors.

CIN::APSE Compression Technology


It takes more than an ordinary connector to support advanced performance interconnect applications. It takes CIN::APSE, a proven solderless compression connector technology that offers exceptional mechanical and electrical performance at signals well above 20 GHz.

If you have an interconnect challenge, and need to overcome the restrictions of ordinary connector devices, CIN::APSE can provide the versatile and reliable interconnect solution you need.

Innovative Compression-Mount Technology

CIN::APSE is a unique, compression interconnect technology which provides superior mechanical and electrical performance. The contact construction consists of randomly wound gold plated molybdenum wire, formed into a cylindrical shape (Figure 1). Standard contact diameters are 0.020" (0.508 mm) and 0.040" (1.016 mm).

The basic CIN::APSE contact configuration consists of a contact installed into a customized plastic insulator with the patented Cinch hourglass hole design. Once in place, the contact extends on both sides of the insulator.

Quick, Solderless Installation

CIN::APSE is easily installed in two basic steps, without soldering. First, using alignment features, the CIN::APSE interconnect is positioned between two components with matching connection footprints. Next, the two components are compressed and fastened together. It's as simple as that.

Low Compression Force, Low Contact Resistance

The CIN::APSE contact offers one of the best force/deflection ratios in the industry. An average compression force of only 2.5 ounces will yield a typical contact resistance of less than 20 mOhms. This means high I/O count applications can achieve excellent electrical performance with only minimal compression force.

*Test results are pass/fail criteria, not limitations of the technology.


  • Solderless RoHS compatible
  • High density/low profile
  • Multi-point contact/mechanical wipe
  • Minimum contact spacing of 1.0mm (.039)
  • Low profile height of .8mm (.032)
  • High frequency capability up to 50 GHz and beyond
  • Short signal path allows for minimal FEXT/NEXT
  • Custom Configurations

Microminiature-D Connectors: Dura-Con


The Cinch Microminiature Dura-Con line of connectors qualified (QPL) to MIL-DTL-83513 is one of the most widely used .050 inch (1.27mm) pitch connectors for military and high-end commercial applications. Dura-Con is ideal where packaging requires a small size and low weight, as well as a highly reliable and rugged connector that has electrical and mechanical integrity under extreme vibration and shock conditions. The heart of the Dura-Con System is the unique wire form pin that provides seven points of contact when mated to the socket. Applications include electronics in missiles, aircraft, launch vehicles, satellites and computers.

Dura-Con connectors are available as all plastic in 9, 15, 21, 25, 31, 37 and 51 positions and metal shell versions in 9, 15, 21, 25, 31, 37, 51 and 100 positions. In addition, Cinch also offers Metal Shell Micro Edge Dura-Con Connectors in 128 and 184 positions, strip connectors up to 60 positions and connector savers. Termination can be solder cup, wired leads or PC mount.
