142V and 142R use lever-operated spring connections for PCB wiring. V models present the conductor entry vertically to the board, while R models turn the entry horizontally. Each pole has two solder pins in rows spaced 7.62mm apart. Choose the entry orientation and the exact pitch before selecting the pole count.
