What are the key features of SMS-101-01-FM-D?
- 2-position dual-row micro socket on a fine 0.050" x 0.100" mixed pitch for ultra-compact through-hole signal connections
- Flush-mount (-FM) design minimizes connector protrusion above the PCB surface, reducing overall assembly height
- Through-hole termination provides robust mechanical retention for connectors subject to repeated mating cycles or vibration stress
What is SMS-101-01-FM-D used for?
The SMS-101-01-FM-D is used for low-pin-count signal interfaces on compact sensor modules, precision instrument daughtercards, and miniaturized embedded boards where a fine 0.050" x 0.100" pitch is required to fit within a tight footprint. Its 2-position dual-row through-hole construction offers stronger mechanical pull-out resistance than surface-mount alternatives, making it reliable in field-service applications where connectors are repeatedly mated and unmated.

Frequently Asked Questions
What pitch configuration does the SMS-101-01-FM-D use, and how does the mixed 0.050" x 0.100" spacing benefit compact PCB layouts?
The SMS-101-01-FM-D uses a 0.050" row pitch combined with a 0.100" column pitch across its 2-position dual-row through-hole layout. This mixed pitch allows a very small footprint compared to standard 0.100" x 0.100" sockets, enabling placement in tight PCB areas on sensor modules or miniaturized instrument boards while still providing reliable mechanical retention from through-hole termination.
What does the flush-mount (-FM) designation mean for the SMS-101-01-FM-D, and in which assembly scenarios is it most beneficial?
The flush-mount (-FM) style positions the SMS-101-01-FM-D's mating interface at or very close to the PCB surface, minimizing the connector's above-board protrusion. In thin product enclosures or stacked PCB assemblies where overall height is limited to a few millimeters, this low-profile through-hole socket ensures the 2-position interface does not violate mechanical clearance constraints imposed by the chassis or adjacent boards.
When would an engineer choose the SMS-101-01-FM-D over a surface-mount micro socket for a field-service instrument?
Through-hole termination on the SMS-101-01-FM-D provides superior mechanical pull-out strength compared to surface-mount pads, which is critical in field-service instruments that undergo frequent connector mating cycles. For a 2-position signal interface on a handheld measurement device that may be plugged and unplugged hundreds of times, the through-hole solder joints resist the lateral and axial forces that would eventually lift SMT pads from the PCB.
