Product Overview
Microtech CP-40-1 is a subminiature coaxial connector component kit for assembling or repairing single-contact micro-coaxial terminations. Microtech, Inc. of Folcroft, PA produced this connector family for precision dynamic measurement applications where standard-sized coaxial hardware is too heavy, too large, or mechanically incompatible with the target receptacle. The kit supplies the four discrete components needed to hand-terminate a micro-coaxial cable end: a gold-plated pin contact, hex nut, washer/ring, and insulator sleeve. Protected under US Patent Nos. 3,601,766 and 3,611,273.
Key Features
- Subminiature single-contact coaxial connector component kit
- Four-piece assembly: gold-plated cylindrical pin contact, hex nut, washer/ring, and insulator sleeve
- Gold-plated brass/metal contact and hardware components
- Solderless or solder-type termination design
- Intended for micro-coaxial cable termination - incompatible with standard RG-58, RG-174, or RG-178 cable without verified gauge match
- Cannot mate directly with BNC, SMA, SMB, or MCX interfaces without an adapter
- Covered by US Patent Nos. 3,601,766 and 3,611,273
Applications
- Vibration lab technician hand-terminating a custom-length micro-coaxial cable to connect a triaxial IEPE accelerometer to a data acquisition system - where a pre-molded assembly would add too much mass or stiffness to the test structure
- Test engineer building a lightweight, custom accelerometer cable for high-vibration structural or aerospace testing where cable snag or mass-loading errors must be eliminated
- Biomedical equipment technician replacing a severed micro-coaxial connector termination inside a compact transducer probe or high-density medical instrument housing under a microscope
- Metrology specialist repairing or extending sensor cabling on vintage Microtech, Malco, or Microdot-compatible transducers and measurement equipment
- Maker or electronics hobbyist working with miniature RF or sensor circuits who needs a period-correct subminiature coaxial termination for a custom build or restoration project
Frequently Asked Questions
What is the thread size or mating interface for this connector?
Thread size is not confirmed for this specific kit. Subminiature connectors from Microtech, Malco, and Microdot of this era used highly specific thread pitches - verify the exact thread pitch of your receiving jack before ordering. These components are not interchangeable with BNC, SMA, SMB, or MCX interfaces without an adapter.
What cable gauge does this kit fit?
Compatible cable gauge is not confirmed. These components require specialized micro-coaxial cable of matching gauge. Standard coaxial cables (RG-58, RG-174, RG-178) are unlikely to be compatible without verified gauge matching against the connector bore.
What tools are needed to assemble this connector?
Precision micro-soldering or micro-crimping tools are required, along with appropriate wire stripping tools for micro-coaxial cable. Assembly of components this small is typically performed under magnification. Tooling is not included.
Is this a complete connector or just the termination components?
This is the termination component kit for one cable end - four loose pieces: pin contact, hex nut, washer/ring, and insulator sleeve. The mating receptacle (jack on the transducer or instrument side) is not included and must be sourced separately.
Somewhere in a metrology lab, a cable is one good termination away from a clean measurement. These four small pieces - pin, nut, ring, insulator - are the part that closes the loop.
