Application for SPTH PCB terminal blocks

PCB all-rounder: Made for building technology and industrial applications

Whether in buildings, as in the example of a damper actuator shown here, or in classic industrial applications for controllers and frequency converters, the form factor of the MKDS product family is indispensable. Which is why it is now reinventing itself – faster, simpler, more innovative, but with the same distinct character. The result of this reinvention is the SPTH 1,5 series.

Your advantages


Advantages of the SPTH series: space savings of 20% compared to comparable Push-in terminal blocks

Compact dimensions Space savings of 20% compared to comparable Push-in terminal blocks

The new SPTH 1,5 series enables you to benefit from a particularly compact design that takes up around 20% less space than conventional terminal blocks with Push-in connection. This enables even more efficient use of your PCB and creates more space for additional components or functions. Despite its small size, operation is convenient and the connection quality is of the usual high standard.

Advantages of the SPTH series: uniform design and identical pinning for Push-in and screw connection

TWIN design Uniform design and identical pinning for Push-in and screw connection

The innovative TWIN design ensures maximum flexibility and compatibility. Both connection methods – Push-in and screw connection – have a uniform design and identical pinning. You are thus able to quickly and easily switch between technologies without having to make any changes to the PCB layout or the device housing. This makes planning easier, speeds up production, and reduces purchasing and storage costs.

Advantages of the SPTH series: quick and convenient testing with the integrated touch connection for voltage testers

Large test opening Quick and convenient testing with the integrated touch connection for voltage testers

The SPTH 1,5 series PCB terminal block is equipped with a generous opening for efficient and safe testing in the field. This integrated testing option facilitates quick and convenient testing with all standard test probes up to Ø 2 mm. This saves you time during commissioning and troubleshooting and increases the reliability of your application.

Advantages of the SPTH series: optimum positioning in the assembly process

Solder pins with insertion geometry Optimum positioning in the assembly process

The optimized geometry of the solder pins facilitates the assembly process. The special insertion shape means that the pins are inserted precisely and securely into the PCB, thereby reducing the mounting effort. The result is a reliable and durable electrical connection.

Advantages of the SPTH series: Push-in Technology

Push-in Technology Time-saving conductor connection and long-term stable connection

The Push-in Technology of the SPTH series ensures time-saving and tool-free wiring. Rigid and flexible conductors with ferrules can be connected easily and safely without using additional tools. This not only saves valuable installation time, but also results in a permanently reliable connection. You thus benefit from quick, easy, and efficient installation in any application. All conductor types are released intuitively using the color-coded actuating push button.
