Description

PCB terminal block, 250 Series, 45 °conductor entry to boardEasily, quickly and safely connect conductors with this PCB terminal block (item number 250-408/353-604). It offers the flexibility needed for different mounting types. Rated current and voltage are key factors to consider when selecting a PCB terminal block, as they indicate how the product can be used. This product has a rated voltage of 160 V and a rated current of 4 A. Strip lengths must be 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®. Our Push-in CAGE CLAMP® is a universal, maintenance-free connection solution for all conductor types, boasting a key feature: both solid and fine-stranded conductors with ferrules can be directly inserted without the need for tools or any preparation, such as crimping the ferrule. The item’s dimensions are 21.5 x 16.7 x 12 mm (width x height x depth). This PCB terminal block is suitable for conductor cross sections ranging from 0.14 mm² to 0.5 mm². It comes with one level and eight clamping points that you can use to connect 8 poles. The clamping spring is made of a Copper alloy and the black housing is made of polyamide (PA46) for insulation. The contact surface is coated with tin. This PCB terminal block is operated with a push-button. The PCB terminal block is designed for THR soldering. Insert the conductor at a 45° angle.. The solder pins are organized over the entire terminal strip (staggered). They are 0.4 x 0.75 mm and 2.4 mm in length. Each potential has one solder pin.

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/.
