What are the key features of TSM-133-02-LM-DH-A-K-TR?
- 66-position dual-row SMT terminal strip at .100" (2.54 mm) pitch with low-magnetic (LM) contact material for use in MRI, scientific instrumentation, and magnetically sensitive assemblies
- Kinked (K) SMT tails maintain co-planarity across all 66 positions, ensuring consistent solder joint formation during reflow assembly
- Tape-and-reel (TR) packaging enables automated pick-and-place processing for high-throughput SMT production lines
What is TSM-133-02-LM-DH-A-K-TR used for?
The TSM-133-02-LM-DH-A-K-TR is engineered for magnetically sensitive environments such as MRI equipment, scientific particle detectors, and precision measurement instruments where low-magnetic connector materials are required alongside 66-pin dual-row SMT connectivity at .100" pitch. Its low-magnetic (LM) contact alloy minimizes interference with sensitive magnetic field measurements while the kinked tails ensure production-grade solder reliability.

Frequently Asked Questions
Why is the low-magnetic (LM) contact specification on TSM-133-02-LM-DH-A-K-TR important for MRI and scientific instruments?
Standard connector contacts often use magnetic alloys that can distort sensitive magnetic fields in MRI scanners and particle physics equipment. The TSM-133-02-LM-DH-A-K-TR's low-magnetic (LM) contact material exhibits significantly lower magnetic permeability, minimizing field perturbation. For MRI coil assemblies operating in fields above 1.5 Tesla, this prevents image artifacts and ensures accurate field mapping across all 66 positions at 2.54 mm pitch.
How does the 66-position dual-row layout of TSM-133-02-LM-DH-A-K-TR benefit complex scientific instrument backplanes?
With 66 positions in two rows at .100" (2.54 mm) pitch, TSM-133-02-LM-DH-A-K-TR provides 132 total contact points in a single compact SMT connector. This consolidates signal, power, and control lines onto one interface, reducing the number of connectors and cable harnesses in scientific instrument racks while maintaining the low-magnetic material properties required in magnetically sensitive laboratory environments.
When selecting between TSM-133-02-LM-DH-A-K-TR and TSM-133-02-S-DH-A-K-TR, what is the deciding factor?
The LM variant uses low-magnetic contact alloy rather than the standard (S) phosphor bronze or similar material, making TSM-133-02-LM-DH-A-K-TR the required choice when magnetic field interference is a concern. In non-magnetic environments such as standard industrial or telecom boards, the standard (S) variant at the same 2.54 mm pitch and 66-position dual-row configuration is equally suited and typically lower in cost.
