DIVERSE PERSPECTIVES

machine side

This illustration details the insert's base, engineered for secure interfacing with the machine terminal. It features dedicated lateral apertures for streamlined cable access and management. This design ensures reliable power and signal transmission while providing robust mechanical integrity and stable performance in demanding environments, thereby facilitating seamless system integration.

Insert Interconnection

The interconnect architecture features three precision-engineered, silver-plated pins in a specific configuration. This dual-path design supports both robust 40A power delivery and precise 10A signal transmission, ensuring superior conductivity with minimal resistance and long-term operational stability.

MATCHING PRODUCT

CCSM&CCSF

The image displays a 40A crimp terminal pin, designed for use with this insert series. A complementary pair of male and female inserts enables simultaneous signal and current transmission. The surface is plated with 3μm of silver, ensuring low contact resistance, corrosion resistance, and stable electrical performance under high-current conditions.

manual hydraulic clamp

The crimp terminal is secured using a Manual Hydraulic Clamp, which delivers a consistently calibrated clamping force. This method ensures uniform pressure distribution, permanently reinforcing the contact interface. As a result, the connection maintains exceptional electrical stability and mechanical integrity even under high-vibration conditions, providing reliable, long-term performance in demanding environments.
