Features

Pluggable parts need a matching mating half; spring and screw terminals need the correct conductor and termination details. Barrier blocks and terminal strips also vary in fixing arrangement. Battery connectors require the matching contact layout and polarity. Straight and right-angle versions, different pitches and mounting types are listed across the range; check the selected product rather than assuming a shared specification.

Selection Guidance

Choose the connection style first. Next, match pole count and exact pitch, followed by orientation, footprint and fixing geometry. Check conductor size and the selected part’s voltage and current ratings against your requirements. Where several pitch options are listed, confirm which option belongs to the part before committing the board layout.

Frequently Asked Questions

Does the same pitch mean two pluggable parts will mate?

No. Contact layout, housing geometry, polarization and fixing features must also match. Use drawings of both halves to confirm the pairing.

How much space is needed around the connection?

Check wire bend space, the direction of mating and removal, and access for any termination tool. The required clearance depends on the selected part and the surrounding assembly.

What if a rating or dimension is not listed?

Ask for the selected part’s drawing or specification and provide your operating requirements. Do not carry a rating or dimension across from a similar-looking terminal block.

Need a configuration not shown?

Include the part number, mating connector, key dimensions and required quantity in your inquiry.
