Define the Selection Scope

In the domestic terminal block market, brands such as DEGSON, SUPU, Wanjie Electronics, Anytek, and ULO GROUP are among the options to consider when selecting PCB terminal blocks. Product series vary in wiring structures, mounting methods, and application ranges. Before making a selection, it is important to confirm the product type, number of poles, pitch, and wiring method, then compare specific model specifications rather than judging suitability by appearance alone.

Check Key Parameters

PCB terminal block selection requires careful consideration of both electrical performance and mechanical dimensions. Key electrical parameters include rated voltage, rated current, applicable conductor cross-section, insulation resistance, dielectric withstand voltage, and temperature rise. These should be evaluated based on wire size, current-carrying conditions, and the actual operating environment.​

Mechanical factors include terminal pitch, number of poles, pin layout, PCB hole dimensions, mounting height, wire-entry direction, and connection type. For space-constrained equipment, PCB layout and wire-bending clearance should also be considered to ensure proper assembly.​

Ensure Quality and Compatibility

PCB terminal blocks from different brands cannot be considered interchangeable based on appearance or matching pitch alone. Electrical ratings, pin layout, mounting dimensions, and connection structures must also be checked. Selection should be supported by product datasheets, applicable certifications, and material compliance documents, followed by sample assembly, wiring checks, and necessary electrical tests.​

For bulk procurement, product consistency, lot traceability, supply stability, and after-sales support are also important to ensure reliable long-term operation and production continuity.​

Product Matching Solutions

ULO GROUP offers PCB terminal blocks, pluggable terminal blocks, and DIN-rail terminal blocks to meet different industrial connectivity needs.​

For multi-brand selection and benchmarking, existing models can be evaluated against corresponding ULO products based on rated specifications, number of poles, pitch, conductor range, and mounting dimensions. Where dimensional or functional differences exist, sample testing and small-batch trials can help verify compatibility before full-scale adoption.
