Coaxial connector DELOCK 91787 SMB 50 Ω, 1 piece

DELOCK 91787 is an SMB-type coaxial connector with a characteristic impedance of 50 Ω supplied as a single piece. It is designed for radio frequency and signal transmission applications that require SMB interfaces, offering a compact connection solution for measurement equipment, communication devices and cable assemblies. The package includes a matching shrink tube for strain relief and insulation.

Advantages

The SMB connector provides a compact 50 Ω connection with gold-plated contacts for reliable signal transfer and corrosion resistance. Supplied as one piece with a shrink tube, it simplifies installation and improves mechanical stability at the cable termination. Its compatibility with RG-174 and RG-316 type cables allows flexible use with commonly used coaxial assemblies.

Key specifications

How to use

Prepare the RG-174 or RG-316 cable by stripping the outer jacket, braid and dielectric to the dimensions required for SMB termination. Slide the supplied shrink tube over the cable before assembling the connector. Solder or crimp the centre conductor and attach the connector body according to the cable preparation. After assembly, position the shrink tube over the joint and heat it to provide strain relief and electrical insulation.

Recommendations

Use this SMB connector in installations that require a compact 50 Ω RF connection; verify cable compatibility (RG-174 or RG-316) and follow standard RF assembly practices, including proper soldering/crimping and controlled heating of the shrink tube to avoid insulation damage.
