More space on PCBs with new SMT D-sub connectors

13-01-2022 | Provertha | Connectors, Switches & EMECH

Provertha offers a comprehensive D-Sub connector range for an expansive assortment of applications and now also has nine-pin SMT Eurostyle 'Small Space' versions in a new design with a smaller footprint on the PCB in its portfolio. This offers freer assembly space for other components and satisfies the trend towards higher density on the PCB for industrial applications. The high-performance D-Sub connectors from the TMC series in small-space design lower the needed PCB area by up to 25% compared to existing TMC Eurostyle SMT D-Sub versions due to the shortened form. Its reliability under high mechanical loads guarantees sufficient safety reserves in rugged industrial applications. Due to its small mounting height of just 3.6mm, this connector is ideal for miniaturisation in industrial applications and, at the same time, assures that the device interfaces are extremely robust.


The excellent features of the connector incorporate its solid full metal SMT mounting elements, which are firmly fixed to the metal housing. They reliably absorb the insertion and withdrawal forces under mechanical stress and allow effective and reliable grounding. The insulator body, with its integrated pick-and-place area constructed of high-temperature-resistant high-performance thermoplastic and a solid large SMT termination area to satisfy the coplanarity need, ensures the safe SMT application. The black insulator body facilitates simple and straightforward recognition with a vision system. Also, the fully automated SMT assembly and soldering process is assured by tape-and-reel packaging and an integrated pick-and-place area for the vacuum pipette. The SMT mounting brackets absorb the insertion forces and, therefore, protect the contacts. A dual-beam spring contact assures maximum contact reliability.


Further advantages are the high current carrying capacity of 5.7A at 20C and the extended mechanical life of 250 mating cycles. The connectors are offered as male or female versions with assorted mounting options, for example, with through-hole, thread UNC 4-40 or M3, and threaded bolts UNC 4-40 or M3.
