Description
PCB terminal block, 235 Series, push-buttonOur PCB terminal block (item number 235-778) is the ideal way to connect conductors quickly and easily. It is perfect for custom installations with different mounting types. Our PCB terminal block is rated for 320 V and is designed to handle a rated current of up to 17.5 A. As such, it is suitable for high-load applications. Strip lengths must be between 9 mm and 10 mm when connecting conductors to this PCB terminal block. This product features one conductor terminal and utilizes Push-in CAGE CLAMP®. Push-in CAGE CLAMP® connection technology is ideal for connecting all conductor types. It allows direct insertion of both solid and fine-stranded conductors with ferrules without the need for tools—all thanks to its pluggable design. The dimensions are 5.3 x 19.1 x 12.5 mm (width x height x depth). This PCB terminal block is suitable for conductor cross sections ranging from 0.5 mm² to 1.5 mm². Up to one potential / one pole can be connected to this terminal block using one clamping point on one level. The black housing is made of polyamide (PA66) for insulation, the clamping spring is made of chrome-nickel spring steel (CrNi), and the contacts are made of electrolytic copper (ECu). The contact surface is coated with tin. This PCB terminal block is operated with a push-button. THT is used to assemble the PCB terminal block. Insert the conductor into the board at a 0° angle.. The solder pins, which are 0.4 x 0.8 mm in cross-section and 3.6 mm long, are laid out within the terminal block (in-line). There are two solder pins per potential.
