RS PRO PCB Terminal Block 3-Contact 5.08 mm Pitch Through Hole 1 Row CTB0509

The RS PRO CTB0509 PCB Terminal Block is a high-quality electrical connector specifically designed for mounting on printed circuit boards. Featuring three contacts with a 5.08 mm pitch, it offers versatility for a range of PCB wiring applications in industrial, commercial, and electronics system integration environments. Its through-hole configuration delivers secure placement and optimal mechanical retention, making it ideal for assemblies subjected to vibration or movement.

This model is built using polyamide 66 (PA66) housing that is green coloured with UL94-V0 flame retardant properties, combining safety and durability. Its professional rising clamp terminals and captive screw are engineered for easily and securely attaching wires, ensuring consistent and strong electrical connectivity.

Supporting wire sizes from 0.13 mm² to 1.31 mm² (corresponding to 26 - 16 AWG), the block accommodates flexible and solid conductors for both signal and power applications. Rated for up to 300 V and 10 A, it is suitable for low-to-medium power transmission in electronic devices, automation equipment, control panels, and other PCB-based circuits.

Vertical orientation and one row design facilitate straightforward integration into compact PCB layouts. The guided pin alignment and double interlocking mechanism provide increased mechanical strength, while the block is also end stackable for modular installations.

With dimensions of 15.14 mm in length, 8.3 mm in width, and 10.1 mm in depth, the CTB0509 terminal block fits into standard board footprints with minimal space requirements. Its flame retardant PA66 construction enhances reliability, and the block meets general safety standards for industrial use (no specific approvals listed on the evidence).

Secure PCB wire connections for industrial and commercial electronics. Three-contact design for versatile circuit integration. Rising clamp terminals ensure robust, reliable connection. Accommodates a range of wire sizes for power and signal.

Through-hole mounting for mechanical stability. Flame-retardant polyamide 66 housing for safety and longevity.
