PCB Terminal Strips with Push-Buttons 0.5 mm and 1.5 mm 2
2
1 THR (Through-Hole Reflow*), Pin Spacing: 2.5 mm, 3.5 mm
134 250 Series

● Cost-effective integration of high-temperature resistant THR terminal
strips into SMT reflow soldering processes

● Versions with suction pads are available in tape-and-reel packaging
for automated assembly

● Simple, push-in terminations of solid and ferruled conductors

● Push-button operation for connecting of fine-stranded conductors
and removing of conductors

● 45° conductor entry angle provides easy, space-saving wiring
