What to send us

One message, no back and forth.

Part numberThe code from the table. If you have a sample or a drawing, send a photo on WhatsApp.
PolesHow many positions you need, within the range listed for that part.
Plug and headerPluggable blocks are two parts. If you need both the plug and the PCB header, list both part numbers.
QuantityPieces, or sets for a production run.
Wire sizeThe wire you will clamp, so we can check it against the listed wire range.

Reading the table

Pitch: Centre-to-centre distance between poles, in mm. It must match the hole spacing on your PCB. Some parts list two pitches, such as 5.00 / 5.08 mm.
Poles: The range of position counts the part is made in, e.g. 2P – 24P.
Rated V / A: Rated voltage and current as printed in the catalogue.
Wire AWG: Wire range the clamp takes. A dash means no range is printed.
Torque: Tightening torque for the screw, as printed.
Withstand: Every part in the catalogue lists a withstanding voltage of AC 1500 V for 1 minute.
