Key Features
- 30 positions in dual-row 0.100" (2.54 mm) pitch configuration providing 15 contacts per row for SMT board interconnects
- Gold-plated (-K) stainless steel (-SS) contacts for superior corrosion resistance and consistent contact resistance below 20 mΩ
- Surface mount termination supports standard SMT reflow soldering processes at peak temperatures up to 260°C
- Tape-and-reel (-TR) packaging enables high-volume automated pick-and-place assembly with consistent component orientation
Applications
The TSM-115-04-SS-DH-A-K-TR is suited for high-reliability board-to-board and wire-to-board interconnects in industrial control systems, medical devices, and defense electronics where 30-position 2.54 mm pitch SMT connectivity with corrosion-resistant contacts is required. Its stainless steel contacts with gold plating provide long-term reliability in harsh environments with temperature cycling or elevated humidity. The tape-and-reel packaging facilitates automated assembly in high-volume production of embedded systems and data acquisition modules.

Frequently Asked Questions
What makes the stainless steel contacts in the TSM-115-04-SS-DH-A-K-TR superior for harsh environment applications?
The -SS suffix specifies stainless steel contacts, which offer higher corrosion resistance and mechanical strength compared to standard phosphor bronze contacts. Combined with the gold (-K) plating on mating surfaces, these contacts maintain contact resistance below 20 mΩ in high-humidity, temperature-cycling, and chemically challenging environments found in industrial, medical, and outdoor electronics applications.
How many positions does the TSM-115-04-SS-DH-A-K-TR provide and how are they configured?
The TSM-115-04-SS-DH-A-K-TR provides 30 total positions arranged in a dual-row (DH) configuration at 0.100" (2.54 mm) pitch, with 15 contacts per row. This layout delivers 30 signal or power connections in a compact SMT footprint, making it suitable for data acquisition modules and embedded computing boards requiring dense but manageable interconnect arrays.
Which reflow soldering profile is compatible with the TSM-115-04-SS-DH-A-K-TR for SMT production?
The TSM-115-04-SS-DH-A-K-TR supports standard SMT reflow soldering with peak temperatures up to 260°C for 10 seconds per IPC/JEDEC J-STD-020 guidelines. The tape-and-reel (-TR) packaging ensures consistent orientation during automated pick-and-place placement, enabling accurate soldering of all 30 positions with standard lead-free solder paste in high-volume production environments.
When is the TSM-115-04-SS-DH-A-K-TR a better procurement choice than a standard phosphor bronze contact version?
The TSM-115-04-SS-DH-A-K-TR with stainless steel contacts is the preferred procurement choice for applications exposed to corrosive atmospheres, high humidity above 85% RH, or temperature cycles exceeding 1000 cycles from -40°C to +85°C. While it may carry a small cost premium over standard phosphor bronze contact versions, the extended contact life and reduced field failure rate make it cost-effective for medical devices, outdoor industrial equipment, and defense electronics.
