Description
PCB terminal block, 250 Series, with 3.5 mm pin spacingOur PCB terminal block (item number 250-208/353-604) simplifies electrical installations. You can rely on trusted safety with these PCB terminal blocks, perfect for a wide range of applications when designing your devices. Rated current and voltage are important parameters when selecting a PCB terminal block, as they indicate possible applications and uses. This product has a rated voltage of 320 V and a rated current of 8 A. Ensure that the strip lengths are between 8.5 mm and 9.5 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. Both solid and fine-stranded conductors with ferrules can be plugged in without the need for tools—all thanks to its pluggable design. Dimensions: 29.5 x 15.5 x 12 mm (width x height x depth). This PCB terminal block is suitable for conductor cross sections ranging from 0.2 mm² to 1.5 mm². Up to eight potentials / eight poles can be connected to this terminal strip using eight clamping points on one level. The black housing is made of polyamide (PA46) for insulation and the clamping spring is made of a Copper alloy. Tin is used for coating the contact surfaces. A push-button is used to operate this PCB terminal block. THR is used to assemble the PCB terminal block. The conductor is designed to be inserted into the board at a 45° angle.. The solder pins measure 0.4 x 0.75 mm in cross-section and 2.4 mm in length and are organized over the entire terminal strip (staggered). There are one solder pin per potential.

Notes
| Note | Application notes:Suitable for lead-free, reflow-soldering profiles per DIN EN 61760-1 and IEC 60068-2-58 up to max. 260°C peak temperature. Due to application-specific variables (component configuration and orientation, type of soldering machine, solder paste), trial runs are recommended to ensure product and process compatibility under actual manufacturing conditions. |
