Description

PCB terminal block, 250 Series, solder pin dimensions 0.4 x 0.75 mmQuick and easy connections are guaranteed with this PCB terminal block (item number 250-203/353-604/997-404). You can count on proven 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 determine the product’s suitability for different applications. 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 pushed in without needing to use any tools—all thanks to its pluggable design. Dimensions: 12 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 three potentials / three poles can be connected to this terminal strip using three clamping points on one level. The clamping spring is made of a Copper alloy and the black housing is made of polyamide (PA46) for insulation. Tin is used for coating the contact surfaces. This PCB terminal block is operated with a push-button. THR is used to solder the PCB terminal block. Insert the conductor at an angle of 45°.. The solder pins, which are 0.4 x 0.75 mm in cross-section and 2.4 mm long, are laid out over the entire terminal strip (staggered). There are one solder pin per potential.

Specification

Notes

NoteApplication 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.
Variants:Other pole numbers, Direct marking, Other versions (or variants) can be requested from WAGO Sales or configured at https://configurator.wago.com/.
