9.5mm PCB Screw Terminal Blocks and Barrier Connectors

This collection covers 9.5mm pitch through-hole PCB screw terminal blocks selected from five product listings. Available formats include HB-9500 barrier-style blocks, 950-series spliceable modules and 45R/45RM right-angle blocks. The actual variants span 2 to 10 positions, with package quantities that vary by listing.

What Is a 9.5mm PCB Terminal Block?

A 9.5mm terminal block places adjacent connection centers 9.5mm apart. It provides more physical spacing than 6.35mm or 7.62mm products, but pitch alone does not define voltage, current, wire capacity, insulation performance or regulatory suitability. The PCB footprint and complete component specification must match the application.

Products and Options in This Collection

HB-9500 blocks without a cover in 2P, 3P, 4P, 5P and 6P options
HB-9500 barrier blocks with a lid in 2P–10P options
45R/45RM right-angle blocks in 2P–10P, with or without mounting holes
950-series 9.5mm spliceable blocks in 2P and 3P options
Mixed-pitch listings offering separate 6.35mm, 7.62mm and 9.5mm variants

How to Select the Correct Terminal Block

Select the exact 9.5mm pitch option where a listing contains multiple pitches.
Choose the required number of positions, from 2P to 10P depending on the product.
Choose the physical format: covered barrier block, uncovered block or right-angle block.
For 45R/45RM variants, select with or without mounting holes.
Confirm whether the package contains 2, 5, 10 or 50 pieces.
Check the PCB hole pattern, lead dimensions, body width, mounting-tab location and wire-entry clearance.
Validate the exact product’s conductor range, tightening torque, voltage/current ratings and required approvals.

Right-Angle and Standard Barrier Formats

The 45R/45RM listing currently exposes right-angle variants only. Its options distinguish 2P–10P sizes and versions with or without mounting holes. HB-9500 listings use a different barrier-block body and are offered with or without a cover depending on the product. Shared 9.5mm pitch does not make these footprints or mounting geometries interchangeable.

Mixed-Pitch Product Boundaries

Two listings combine 6.35mm, 7.62mm and 9.5mm options. Only variants explicitly labeled 9.5mm Pitch or 950-9.5mm Pitch belong to this collection’s mechanical scope. The 6.35mm and 7.62mm options require different PCB spacing and must not be substituted.

Ratings and Compliance

Source claims differ by product. Several listings state 300V/30A, while the 45R/45RM listing separately states IEC 750V/32A and UL 300V/20A. Conductor claims also vary between 22–10AWG and 22–12AWG. These values are not a universal collection rating. Certification terms in marketplace titles or descriptions do not replace traceable documentation for the exact ordered component.

A 9.5mm pitch does not by itself prove suitability for mains input, three-phase equipment, high-voltage systems, IEC 60664 pollution degree 3, outdoor use or harsh environments. Final suitability depends on certified component data, PCB creepage and clearance, insulation system, enclosure, contamination level, wiring, temperature and the applicable equipment standard.

Compatibility Limits

HB-9500, 950, 45R and 45RM are listing identifiers, not proof that products from different manufacturers share the same footprint. Before replacing an existing terminal block, compare pitch, pin diameter, PCB drilling, barrier shape, terminal height, screw access, mounting tabs and body dimensions.

Common Applications

When the exact part is properly specified, 9.5mm PCB screw terminal blocks can support power distribution, industrial controls, power supplies, converters, motor-control equipment and other PCB-to-wire connections requiring a wide terminal pitch. Application examples do not establish an electrical rating.

Frequently Asked Questions

Is 9.5mm the same as 0.375 inch?
It is approximately 0.374 inch and is commonly described as 0.37 inch. Always design from the stated metric pitch and drawing rather than a rounded inch value.

Can a 9.5mm block replace a 7.62mm block?
No. The PCB hole spacing and body dimensions differ.

Are all products rated 30A?
No. The source listings publish different rating systems and values. Verify the exact variant and supporting documentation.

Are all options spliceable?
No. Some 2P/3P products are described as spliceable, while the multi-position barrier blocks are configured as complete position-count variants. Do not assume every housing can be joined end to end.

Does every 45R/45RM option include mounting tabs?
No. Separate variants are offered with and without mounting holes.

Are covers included?
It depends on the product. One HB-9500 listing specifies no cover, while another describes a lidded barrier format.

Ordering Checklist

Confirm 9.5mm pitch, position count, terminal orientation, cover style, mounting-hole requirement, PCB footprint, conductor range, package quantity, exact ratings and compliance documents before ordering.
