Product Overview
Malco Microdot part number 033-0111-0001 is a straight between-series RF coaxial adapter engineered to couple standard BNC instrumentation lines with miniature threaded coaxial connectors. Built with a bayonet coupling collar on one end and a threaded screw-on interface with hex wrench flats on the other, this unit provides a direct physical transition between distinct coaxial formats.
Key Features
- Interface Side A: Standard two-stud BNC plug with knurled bayonet coupling sleeve
- Interface Side B: Miniature screw-on coaxial interface with machined hex flats
- Center Contacts: Gold-plated male pins on both mating ends
- Insulation: Solid white dielectric insert
- Body Construction: Machined metal shell with knurled grip ring
- Design Configuration: Straight between-series coaxial feed-through adapter
Applications
- Interfacing legacy test bench instrumentation to miniature sensor and accelerometer cabling
- Connecting laboratory RF equipment directly to vintage Microdot instrumentation lines
- Custom RF signal routing and bench prototype setups requiring bayonet-to-screw-on transitions
Frequently Asked Questions
What interfaces does this coaxial adapter join?
This adapter mates a standard BNC bayonet connection on one end to a miniature threaded coaxial screw-on connector on the other, with male center pins present at both interfaces.
Are there any part numbers stamped on the metal connector body?
The connector body has no stamped or etched part numbers. The part number 033-0111-0001 is identified from the intake documentation.
Does this adapter require special tools for installation?
The BNC side connects by hand using the knurled bayonet collar, while the rear threaded connector includes machined wrench flats to assist in secure tightening during installation.
What contact gender is featured on each mating end?
Both ends feature male center conductor pins. One end couples via a standard male BNC bayonet sleeve, and the opposing end mates with an internal threaded screw-on coupling.
Bridging different coaxial standards is never glamorous until an older sensor on the bench suddenly speaks clearly to modern test gear. Thread the rear coupling tight, twist the bayonet, and let the measurement run.
