Overview
The M20-7851046 is a 20-position, dual-row female receptacle designed for 2.54mm (0.100 inch) pitch board-to-board or cable-to-board connections. This through-hole connector features a versatile design that allows for both top and bottom entry, providing flexibility for vertical stack height management and PCB layout. It is rated for a current of 3A and features a durable housing with a UL94V-0 flammability rating.
Why Choose This Part
The dual-entry design allows pins to pass through the PCB from the bottom, enabling low-profile stacking configurations. With a durability rating of 300 mating cycles and a wide operating temperature range of -25C to +105C, it offers high reliability for prototyping and production industrial environments.
Applications
Mezzanine Board Stacking
Used to connect secondary PCBs to a main carrier board in industrial and embedded systems.
I/O Breakout Headers
Provides a reliable interface for connecting external ribbon cables or sensor arrays to a microcontroller board.
Power Distribution Rails
