142V 142R 5.08mm 7.62mm PCB Terminal Block — Vertical & Right-Angle Industrial Connector
142V & 142R 5.08mm & 7.62mm PCB Terminal Blocks — Vertical and Right-Angle Industrial Wire Connectors
The 142V (vertical) and 142R (right-angle) PCB terminal blocks in 5.08mm and 7.62mm pitch bring the choice of wire entry direction to industrial-rated terminal blocks. The 142V variant accepts wire from above the PCB (vertical entry), while the 142R accepts wire horizontally from the PCB edge (right-angle entry). Both are rated for industrial voltages and currents (300V/15A at 5.08mm; 300V/24A at 7.62mm), making them suitable for industrial control panels, motor drives, power distribution boards, and panel-mount industrial equipment where the wire entry direction is dictated by the enclosure design.

142V vs 142R — Choosing Wire Entry Direction for Industrial Designs
142V (vertical): Wire enters from above. Best for horizontal PCBs in open enclosures, DIN rail-mounted control boards, and designs where wires drop vertically onto the PCB. 142R (right-angle): Wire enters horizontally from the PCB edge. Best for vertical PCBs in panel-mount enclosures, designs where wires must enter from the front or side of the panel, and space-constrained enclosures where vertical wire routing is not possible.
Ideal Applications
- Industrial control panel PCBs with panel-mount wire entry (142R)
- DIN rail-mounted control boards with top-entry wiring (142V)
- Motor driver and VFD control board power connections
- Industrial power distribution board bus connections
- Building automation and HVAC controller I/O terminals
Frequently Asked Questions
Q: Can I use 142R right-angle terminal blocks for panel-mount designs?
A: Yes. 142R right-angle terminal blocks are specifically designed for panel-mount applications where wires enter horizontally from the front or side of the enclosure, with the PCB mounted vertically behind the panel.
Q: Are 142V/142R footprints compatible with KF128 fixed terminal block footprints?
A: The pitch is the same, but the overall footprint dimensions differ between 142V/142R and KF128 series. Verify the specific footprint in your EDA library before substituting.
