What are the key features of STMM-114-02-L-D-SM?

  • 28-position dual-row shrouded terminal strip with 2 mm pitch
  • Gold-over-nickel (Au on Ni) mating finish for corrosion resistance and low contact resistance
  • Phosphor bronze square-pin contacts for strong spring force and durability
  • Shrouded housing polarizes cable-mate connections to prevent mismating

What is STMM-114-02-L-D-SM used for?

The STMM-114-02-L-D-SM shrouded terminal strip is designed for cable-to-board signal routing in embedded control systems, industrial automation equipment, and instrumentation modules. Its 28-pin dual-row 2 mm pitch layout supports moderate pin-count cable harnesses with a secure, polarized connection. The gold-over-nickel contact finish ensures reliable low-resistance mating in demanding industrial environments where repeated mating cycles are expected.

Frequently Asked Questions

What is the contact finish and contact material used in the STMM-114-02-L-D-SM?

The STMM-114-02-L-D-SM uses Gold (Au) over Nickel (Ni) on the mating surfaces and Tin (Sn) over Nickel (Ni) on the termination side, with phosphor bronze square-pin contacts. This combination delivers low contact resistance, excellent corrosion protection, and strong spring-force retention across repeated mating cycles in industrial and instrumentation cable assemblies.

How does the 2 mm pitch on STMM-114-02-L-D-SM compare to standard 2.54 mm connectors for board density?

The 2 mm pitch of STMM-114-02-L-D-SM provides approximately 21% tighter contact spacing than a standard 2.54 mm pitch connector, enabling a 28-pin dual-row footprint to occupy significantly less PCB real estate. This makes it preferable in space-constrained embedded modules and instrumentation boards where fitting 28 pins at 2.54 mm pitch would exceed available area.

What applications benefit most from the shrouded design of STMM-114-02-L-D-SM?

The shrouded housing on the STMM-114-02-L-D-SM provides keyed polarization that prevents misaligned or reversed cable-mate insertion across its 28 positions. This is especially valuable in industrial automation panels and field-service environments where connectors may be mated under low-light or high-vibration conditions, reducing the risk of damaged PCB traces or incorrect signal routing.
