SMZ M CRIMP for RG188 Cable

Description

The SMZ Male (Plug) Crimp Connector for RG188 is a specialized 75-Ohm RF interface designed specifically for the digital telephony and telecommunications sectors. Widely known as the BT43 connector, the SMZ series provides a more robust and larger-scale interface than the standard SMB, specifically tuned to maintain 75-Ohm impedance for digital signals such as E1, E3, and DS3. This crimp-style variant is optimized for high-volume field installations, offering a fast and highly repeatable termination process for high-performance micro-diameter cables.

Precision-machined for the exact geometry of RG188 cable, this connector utilizes a dual-crimp termination for the center pin and the outer ferrule. This ensures a gas-tight, vibration-resistant mechanical bond that maintains signal integrity even in high-density distribution environments. The snap-on coupling mechanism allows for quick “push-to-lock” mating with SMZ female jacks, providing a secure electrical connection with a distinct tactile click. Manufactured with a gold-plated brass body and premium PTFE (Teflon) insulation, it ensures low insertion loss and superior protection against environmental oxidation.

Key Technical Advantages

• 75-Ohm Impedance Precision: Specifically engineered for telecommunications standards, minimizing return loss and preventing data errors in high-speed digital circuits.

• RG188 Precision Fit: Specifically calibrated for the dimensions of RG188 cable, ensuring a secure mechanical grip and optimized signal transition.

• High-Strength Dual Crimp: The industrial crimp design for both the center contact and outer sleeve provides maximum pull-off resistance and excellent EMI/RFI shielding.

• Telecommunications Grade Reliability: Designed for the rigors of central office exchanges, providing a more substantial mechanical lock than standard 75-Ohm SMB connectors.

• Superior Corrosion Protection: High-grade gold-over-nickel plating on all critical surfaces ensures low contact resistance and prevents oxidation over long-term deployments.
