SMA jack for crimping RG-174 / RG-316 DeLOCK 90037

The DeLOCK SMA jack for crimping RG-174 / RG-316 (model 90037) is a compact coaxial connector intended for use in radio frequency technology. It provides a 50 Ω impedance and gold-plated contacts to ensure reliable conductivity. The connector is supplied with matching shrink tube and is available in packs of five. Its brass finish and small dimensions (8 mm width × 19.8 mm depth × 8 mm height) make it suitable for tight installations and various RF applications.

Advantages

The SMA jack features gold-plated contacts for improved electrical contact and corrosion resistance, a standardized 50 Ω impedance for RF compatibility, and a compact brass body that fits limited-space assemblies. Inclusion of matching shrink tube simplifies cable finishing and provides additional strain relief. Supplied in packs of five to cover multiple connections or spare needs.

Key specifications

How to use

Prepare the RG-174 or RG-316 cable by stripping the outer jacket, braid and dielectric according to the connector manufacturer’s crimping specification. Slide the supplied shrink tube and crimp ferrule onto the cable, insert the center conductor into the gold-plated pin, and position the connector body over the cable. Crimp the ferrule with a suitable crimping tool, then apply heat to the shrink tube to secure and insulate the termination. Verify mechanical stability and electrical continuity before final installation.

Recommendations

Use the correct crimping die for RG-174 or RG-316 and inspect each termination for proper crimp depth and secure contact. Avoid excessive heat when shrinking the tube to prevent damage to the dielectric or plating.
