Overview

The TSW-140-07-G-S is a single-row, 40-position terminal strip header with a standard 0.100 inch (2.54mm) pitch. This through-hole connector features phosphor bronze contacts with gold-over-nickel plating on the mating post and matte tin on the solder tail, ensuring reliable electrical connectivity and corrosion resistance. With a high current rating of 5.7A per pin and an operating temperature range of -55C to 125C, it is designed for robust board-to-board or cable-to-board interconnects.

Why Choose This Part

The TSW series is known for its versatility and durability, featuring a square post design that ensures a high-integrity connection with mating sockets. The PBT insulator is rated for high-temperature environments, and the 5.7A current capacity exceeds that of many generic headers, making it suitable for power delivery alongside signal paths.

Applications

Custom PCB Shield Stacking
Ideal for creating stackable daughterboards or expansion shields where a 40-pin interface is required.
Industrial Control Backplanes
Used as a vertical signal interface for industrial automation modules requiring high current delivery.
Prototype Development
Standard 0.1 inch spacing allows for easy integration with perforated prototyping boards and breadboard-style modules.
