What are the key features of T1M-20-F-SV-L-K?
- 20-position single-row female terminal strip at 1.00 mm pitch for high-density wire-to-board connections
- Keyed (K suffix) housing prevents mis-mating and ensures correct polarity in field-service environments
- Vertical through-hole mounting for robust PCB solder joint retention in wire harness assemblies
- Samtec T1M series compatible with T1M male counterparts enabling reliable 20-signal discrete wire interconnects
What is T1M-20-F-SV-L-K used for?
T1M-20-F-SV-L-K is used in wire-to-board applications requiring 20 discrete wire connections at 1.00 mm pitch in embedded systems, instrumentation, and industrial electronics where space-efficient connectors are essential. The keyed housing prevents reversed insertion during field assembly or maintenance, reducing risk of mis-wiring in multi-channel signal and power circuits. This terminal strip suits robotics controller boards, sensor interfaces, and custom cable harnesses where 20 signals must transition from flexible wire to PCB at fine pitch.

Frequently Asked Questions
How does the keying feature on T1M-20-F-SV-L-K prevent mis-mating in multi-connector assemblies?
T1M-20-F-SV-L-K includes a keyed housing (K suffix) that physically prevents insertion into the wrong 20-position connector position in multi-connector PCB layouts. The keyed polarization ensures correct wire-to-board alignment even in low-visibility or blind-mating assembly environments. At 1.00 mm pitch with 20 positions, keying is critical to prevent accidental signal reversal across the 20-conductor harness.
What pitch and position count does T1M-20-F-SV-L-K use, and how does it compare to similar 1.27 mm pitch strips?
T1M-20-F-SV-L-K provides 20 positions in a single-row configuration at 1.00 mm pitch, resulting in a total mated length approximately 30% shorter than equivalent 1.27 mm pitch terminal strips with the same position count. The finer 1.00 mm pitch enables higher density PCB designs where each millimeter of board space matters, at the cost of reduced current capacity per pin compared to wider-pitch alternatives rated above 1 A per contact.
Can T1M-20-F-SV-L-K be mated with the T1M-20-T-SV-L male terminal strip?
Yes, T1M-20-F-SV-L-K female socket mates with T1M-20-T-SV-L male pin strip from the same Samtec T1M series family. Both use 1.00 mm pitch and 20-position single-row layouts ensuring proper signal alignment across all 20 positions. The keyed housing on the female (K suffix) mates with a corresponding polarization feature on the male header to enforce correct orientation in high-density PCB cable assemblies.
What current rating and wire gauge is supported by T1M-20-F-SV-L-K discrete wire contacts?
T1M series connectors at 1.00 mm pitch typically support 26 to 30 AWG wire gauges with current ratings around 1 A per contact at room temperature. For T1M-20-F-SV-L-K, operating 20 contacts simultaneously with derating may reduce per-contact current to 0.5-0.8 A due to thermal bundling effects. Samtec's datasheet specifies the exact crimp tooling and wire preparation requirements for reliable termination at 1.00 mm pitch.
