What are the key features of RSM-124-02-T-S?
- 24-position SMT female socket strip with 0.050" x 0.100" micro pitch for ultra-compact board-to-board receptacle interconnects
- Tin (Sn) over nickel contact termination compatible with standard SAC305 lead-free reflow solder processes up to 260°C
- RoHS-compliant (Pb-free) construction for restricted hazardous substance compliance in consumer, industrial, and commercial electronics
- Compact 1.21 inch (30.7mm) body length in a low-profile 0.1 inch body breadth for tight PCB layout constraints
What is RSM-124-02-T-S used for?
The RSM-124-02-T-S micro socket strip is suited for compact SMT board-to-board and mezzanine interconnects in portable instrumentation, IoT sensor nodes, and wearable electronics where 0.050" x 0.100" pitch minimizes connector footprint compared to full 0.100" pitch alternatives. As a female receptacle it mates with corresponding pin header assemblies in modular designs such as small form-factor compute modules, RF daughterboards, and compact industrial data acquisition units. Its tin-over-nickel finish and RoHS compliance make it appropriate for commercial, consumer, and light industrial electronics requiring lead-free assembly.

Frequently Asked Questions
What is the significance of the 0.050" x 0.100" mixed pitch in RSM-124-02-T-S, and how does it affect mating connector selection?
The 0.050" x 0.100" designation indicates RSM-124-02-T-S uses a non-standard micro pitch combining 0.050" (1.27mm) in one axis and 0.100" (2.54mm) in the other. This mixed pitch requires a specifically matched pin header, enabling a connector that is narrower than a full 0.100" dual-row part while maintaining adequate pin-to-pin spacing for reliable 24-position SMT board-to-board mating.
What contact finish does RSM-124-02-T-S use, and is it compatible with lead-free reflow soldering?
RSM-124-02-T-S uses tin (Sn) over a nickel barrier on the termination contacts and is RoHS-compliant (Pb-free code: Yes). This finish withstands standard SAC305 lead-free reflow profiles with peak temperatures up to 260°C, making it directly compatible with modern PCB assembly processes without requiring special handling or soldering conditions.
For a compact IoT sensor module, how does RSM-124-02-T-S minimize board area compared to standard 0.100" pitch receptacles?
RSM-124-02-T-S features a body breadth of only 0.1 inch (2.54mm) and a 0.050" column pitch, resulting in a significantly narrower footprint than standard 0.100" dual-row receptacles for the same 24-position count. In a compact IoT sensor module where PCB area is at a premium, this micro socket strip can recover several square millimeters of board space versus conventional connector alternatives.
What body length does RSM-124-02-T-S occupy on the PCB, and in which orientation should it be placed for optimal routing?
RSM-124-02-T-S has a body length of 1.21 inches (30.7mm) for 24 positions. Placing the connector parallel to the board edge or alongside the primary signal routing direction allows signal traces to fan out from each of the 24 female contacts with minimal via usage, which is important for keeping impedance consistent on high-frequency signals in small form-factor compute or RF daughterboard designs.
