BlockMaster Electronics is proud to introduce our newest series of exciting products: Panel Feed-Through Terminal Blocks. The Panel Feed-Through Series allows the designer to completely separate the electrical element of a product from the outside world or field connections. In many new designs of motor drives and switching power supplies, it is desirable to separate "noisy" electronics from the outside world. For products such as medical imaging, motion and robotic control motor generator sets, and various high power switching outputs that must meet domestic and international EMI/RFI requirements, our Panel Feed-Through Series is the answer.

Field wiring is outside your enclosure and your products' circuits can be inside a shielded cabinet or box. The MPT line of Feed-Through Terminal Blocks is available with ratings from 24A/450V to 150A/1000V in a series of 10 unique modules. A variety of push-on tab, solder and screw terminations are also available.

Standard color is gray with various other NEMA colors available on special order. Mounting to panels is accomplished with knurled-nut, snap-on wedges or mounting screws depending on the current rating of the module. The individual modules may be snapped together to make a multiple connection module.

(1) Configurations of higher number of poles are obtainable using modular
versions only. In order to avoid interference between the pin and the pcb,
the terminal row should be interrupted when the number of positions exceeds 30.
