XY129 Series 2-Pin Screw Terminal Block – 7.5mm Pitch PCB Mount Connector

Description

The XY129 Series 2-Pin Screw Terminal Block – 7.5mm Pitch PCB Mount Connector is a heavy-duty, highly reliable component for establishing secure wire-to-board connections on printed circuit boards. Designed with a wider 7.5mm pitch spacing, this terminal block provides excellent electrical isolation and clearance, making it ideal for higher voltage and higher current applications compared to standard 5.08mm blocks.

Available at Tomson Electronics, this PCB mount connector features strong metal screw terminals that securely clamp down on stripped wires, preventing accidental disconnections due to vibration or thermal expansion. The modular housing design often allows multiple blocks to be slide-locked together, letting you create custom lengths for larger power distribution boards, motor drivers, and industrial control panels.

Frequently Asked Questions (FAQ)

Q: Why should I choose a 7.5mm pitch over a 5.08mm pitch?
A: The "pitch" is the distance between the center of one pin to the center of the next. A wider 7.5mm pitch provides a larger physical gap between the conductive traces on your PCB. This extra clearance reduces the risk of electrical arcing, making it much safer for routing high voltages (like mains AC power) or handling higher currents without overheating.

Q: Are these terminal blocks interlocking?
A: Yes, standard XY129 series terminal blocks usually feature a dovetail slot and groove on the sides. This allows you to slide multiple 2-pin or 3-pin blocks together to create a rigid 4-pin, 5-pin, or larger continuous terminal block before soldering them into your board.

Q: Do I need to solder the wires into this connector?
A: No. The pins on the bottom of the block are soldered permanently into your PCB. To connect external wires, you simply strip the wire insulation, insert the bare wire into the top slot, and tighten down the screw with a mini screwdriver to lock it in place.
