Phoenix Contact PTSM 0.5/ 4-2.5-V SMD R44 Series PCB Terminal Block, 4-Contact, 2.5mm Pitch, Surface Mount, 1-Row,

This range of the PTSM family Phoenix Contact SMD PCB Terminal Blocks with 2.5 mm Pitch are compact low-profile single piece Wire to Board connectors. The Spring-cage design of these PTSM SMD PCB Terminal Blocks with 2.5 mm Pitch allows a direct plug-in of 0.5 mm² cross-section of solid or stranded conductors which can be uncoupled with via a release button. These PTSM SMD PCB Terminal Blocks with 2.5 mm Pitch are specifically designed to be used in pure SMT processes.
The rated current per cross-section for these PTSM SMD PCB Terminal Blocks with 2.5mm Pitch is 6 A/0.5 mm².
Inflammability rating is UL 94 V-0 for these PTSM SMD PCB Terminal Blocks with 2.5mm Pitch.

A terminal block is simply a link to your PCB. This particular range is a spring cage design which means no tools are needed to install the cables. PCB Terminal blocks are simply soldered onto the PCB and can then be used to transmit data from other sources. Some PCB terminal blocks have multiple levels of connections too. However, the COMBICON range does not.
