Customised connection systems for unlimited functionality
The compactness of the time and monitoring relays from Tele Haase being a first obvious benefit, the relay range indeed features a wealth of other advantages that Weidmüller has supported as a design-in partner
Keeping options open with respect to the device design
Weidmüller and Tele Haase were able to identify the LSF-SMT PCB terminals featuring a pitch of 7.62 mm and designed for lead-free
soldering in the reflow procedure as the ideal solution for signal connectivity. The maintenance-free PUSH IN connection technology allows vibration-free connections that reliably withstand the conditions of all intended relay uses to be created in no time at all. This pays off when the relays are placed in climate boxes to monitor the transportation of pharmaceuticals via the cold chain, for instance.
Tele Haase also benefits from being able to pass on to its customers an all-round, impressively user-friendly concept. As the Tele VEO relays can be installed without tools using PUSH IN connection technology, end users
save valuable time during assembly and can even leave the work to robots. In addition to this, connection options for rigid, single-wire, ultrasonicallycompressed or flexible wires with or without wire-end ferrules and featuring a clamping range from 0.25 to 1.5 mm² provide a high degree of flexibility when connecting the most diverse single-wire cross-sections.
To ensure approval according to UL 840, Weidmüller provided Tele Haase with support as part of a comprehensive service. By means of specially conducted and documented checks in its own accredited laboratory, Weidmüller was able to provide the relay manufacturer with certified connection components for its devices, allowing Tele Haase to carry out UL-compliant device approvals up to 600 V.
“Because Weidmüller kept the options open for us with this kind of device connectivity, we were able to fully concentrate on turning our vision of a relay housing
measuring just 22.5 mm wide and 76 mm deep into a reality,” Reinolt happily acknowledges. “And last but not least, thanks to the practical device connection system we were able to let our ideas flow and so developed a creative relay solution with numerous functions and fields of application.”
