PCB terminal block, 257 Series, with 10 mm pin spacing
Easily, quickly and safely connect conductors with this PCB terminal block (item number 257-860). It offers the flexibility needed for different mounting types. This PCB terminal block has a rated voltage of 1000 V and can handle currents up to 24 A, making it suitable for high-load applications. Ensure that the strip lengths are between 5 mm and 6 mm when connecting conductors to this PCB terminal block. This product features one conductor terminal and utilizes CAGE CLAMP®. Our reliable and maintenance-free CAGE CLAMP® connection makes it easy to connect all types of conductors without having to prepare the conductor. For example, you don't need to crimp ferrules. The dimensions are 12.8 x 24.2 x 14.2 mm (width x height x depth). This PCB terminal block is suitable for conductor cross sections ranging from 0.08 mm² to 2.5 mm². It features one level and a clamping point for connecting a single potential / 1 pole. The clamping spring is made of chrome-nickel spring steel (CrNi), the red housing is made of polyamide (PA66) for insulation, and the contacts are made of electrolytic copper (ECu). The contact surface is coated with tin. Push-button (angled) is used to operate this PCB terminal block. The PCB terminal block is designed for THT soldering. Insert the conductor at a 0° angle.. The solder pins are organized within the terminal block (in-line). They are 0.7 x 0.7 mm cross-section and 4 mm in length. Each potential has two solder pins.
