RESOURCE LIBRARY
Twenty-one buyer tools, connected to the same product data.
Use each resource for its intended job. A guide narrows the field; only exact model data, drawings and samples close the selection.
Search 53 terminal block models
Search by model or pitch, filter by connection family and open model-level product data and technical drawings.
Open the online catalog →Choose a PCB terminal block
Compare connection families and review pitch, poles/positions/ways terminology, wire range, ratings, mounting and document requirements.
Read the selection guide →Compare 5.0 mm and 5.08 mm pitch
Calculate first-to-last contact-center span from 2 to 24 positions and see how the nominal difference accumulates.
Open the pitch calculator →Identify a terminal block and structure a replacement
Use markings, photos, pitch, positions and PCB or mating geometry, then build a checkable email or WhatsApp request without uploading data.
Build a replacement request →Download the 2026 product catalog
Review 53 models across four connection families in an eight-page English PDF prepared for sourcing and RFQ follow-up.
Download the PDF catalog ↗Prepare a complete terminal block RFQ
Use the six-part checklist, then complete up to 20 line items with mechanical, electrical, commercial and document requirements.
Open the RFQ checklist and Excel template →Compare pluggable and PCB screw terminal blocks
Choose between a removable plug-and-header interface and direct screw-clamp conductor termination on the PCB.
Read the architecture comparison →Browse 42 terminal block drawing PDFs
Check public dimension and PCB-interface references for 40 models, with a clear request path for 13 models without a public drawing.
Open the technical drawing library →Compare screw and spring terminal blocks
Compare clamping principle, wiring sequence, tool or actuator access, conductor checks and exact model evidence without assuming a universal winner.
Read the connection comparison →Compare terminal block pitches and measure center spacing
Scan a 2.5–10.16 mm pitch and inch chart, calculate pitch from a first-to-last center span and open current matching model references.
Open the pitch chart and calculator →Convert AWG to mm² and check documented wire ranges
Calculate nominal conductor diameter and area for 8–28 AWG, then open current models whose supplied AWG range includes the selected gauge.
Open the AWG wire size calculator →Check model-level strip length and recommended torque
Compare current supplied values for 39 models, see every missing field and carry the exact conductor and assembly process into confirmation.
Open the installation data chart →Compare terminal block current and voltage by model
Review 42 supplied rating rows, preserve UL/IEC labels and keep 11 unconfirmed Spring references visibly outside the chart.
Open the current and voltage rating chart →Review terminal block samples with one shared record
Use an eight-stage online guide and free three-page PDF for identity, PCB fit, wiring, ratings, documents, findings, actions and sign-off.
Open the sample approval checklist →Verify a pluggable plug and PCB header pair
Check series, pitch, poles, orientation, keying, retention, contact and PCB geometry, ratings, drawings and a fully mated sample.
Open the plug and header matching guide →Compare vertical and right-angle PCB terminal block mounting
Review 33 vertical and 9 right-angle model labels, keep 11 Spring gaps visible and verify wire entry, footprint and enclosure clearance separately.
Open the mounting orientation guide →Review PCB holes, pins and terminal block footprint geometry
Separate pitch, finished holes, pin and row layout, first-pin origin, housing outline, mounting, drawing revision and sample evidence before board release.
Open the PCB footprint guide →Compare up to three current terminal block models
Place family, pitch, positions, mounting, wire range, supplied ratings, drawing status and visible data gaps in one shareable table.
Open the model comparison tool →Send a terminal block quotation or sample request
Keep the company, application, reference model, technical scope, quantity, target market and required documents in one consent-based RFQ.
Start the RFQ form →Compare 14 current 5.08 mm terminal block references
Review Pluggable, PCB Screw and Spring candidates by positions, mounting, supplied ratings, data status and public drawing availability.
Open the 5.08 mm product collection →Separate THT, wave, THR and SMT terminal block assembly
Compare four process terms, avoid mounting and connection-method assumptions, then request ten exact-model design-in and production records.
Open the PCB soldering process guide →BROWSE BY CONNECTION FAMILY
Move from family-level guidance to real model pages.
Each family page links every current model directly, so buyers and crawlers do not depend on submitting a search form to discover product pages.
A resource creates a shortlist—not an approval.
Final pitch, positions, electrical ratings, conductor range, mating compatibility, materials and requested documents must be confirmed against the exact ordered configuration before sample approval or purchase.
