Key Features
- 2-position dual-row micro socket with 0.050-inch x 0.100-inch mixed pitch offers a compact through-hole footprint for fine-pitch signal interfaces
- Through-hole (TH) termination provides robust solder-joint mechanical strength, supporting reliable retention in vibration-prone applications
- Female contact receptacle mates with standard 0.050-inch pitch male pins for direct board-to-board or wire-to-board signal connections
Applications
The SMS-101-02-SM-D is designed for compact 2-signal wire-to-board and board-to-board interfaces in space-constrained embedded electronics, sensor modules, and handheld instruments. Its 0.050-inch by 0.100-inch mixed pitch accepts fine-pitch male pin headers in a through-hole body, allowing reliable reflow or wave soldering to the host PCB. The dual-row female socket configuration supports power and signal pairing in minimal footprint designs where PCB area is at a premium.

Frequently Asked Questions
What is the mixed pitch of SMS-101-02-SM-D and how does it simplify mating with standard pin headers?
The SMS-101-02-SM-D uses a 0.050-inch (1.27mm) pitch within each row and a 0.100-inch (2.54mm) row-to-row pitch, which is a common mixed-pitch geometry in Samtec micro socket families. This combination lets the socket accept standard 0.050-inch pitch micro pin strips on the row axis while maintaining 0.100-inch row spacing that is compatible with many dual-row PCB footprint standards, reducing the need for custom adapter boards.
For a 2-signal sensor interface, how does SMS-101-02-SM-D's through-hole body compare to an SMT micro socket in mechanical retention?
The through-hole body of SMS-101-02-SM-D creates solder fillets in the PCB via barrel, providing mechanical retention forces that are typically 3 to 5 times greater than SMT pad solder joints for the same connector footprint. In sensor applications subject to cable pull or board flexing, this through-hole retention prevents connector lift-off during handling, whereas an SMT micro socket of similar 2-position size may shear from the pads at relatively low lateral forces of 5 to 10 newtons.
Which Samtec male pin series mates directly with SMS-101-02-SM-D for building a detachable 2-position board-to-board interface?
The SMS-101-02-SM-D female socket mates directly with Samtec TSM and TMS series male micro pin strips at 0.050-inch pitch, as well as standard 0.050-inch pitch square-post headers from compatible vendors. For a detachable 2-position board-to-board link, pairing SMS-101-02-SM-D with a TMS-102 male strip creates a compact connector pair spanning approximately 2.54mm x 2.54mm, which is one of the smallest detachable 2-circuit board interfaces available in the through-hole SMT connector ecosystem.
