High-current probeTerminals, busbar contacts
Product Overview
High-current probes are used for electrical testing by supplying high current while making contact with electronic components such as terminals, contacts, and busbars.
Designed with low internal resistance to enable precise signal transmission and measurement, these probes are available in a standard lineup covering rated currents from 20A to 400A.
We offer a variety of probes featuring different tip shapes, tip diameters, spring forces, and materials to suit specific test points.
Carefully selected probe specifications ensure reliable, repeatable contact.
Applications: Aging tests, burn-in tests, formation tests, and DCIR measurement tests.

Characteristics/specification
Example of a representative high-current probe: **High-Current Probe HSS-623**
◆ Designed for low contact and internal resistance, it ensures stable high-current delivery
while minimizing heat generation and voltage drop.
◆ The probe body (HSS-623…M) features an M5 screw mount,
allowing for secure fastening and replacement using a wrench on the hex section (SW6).
◆ Receptacles (KS-623 series) are available in M5 screw-mount and solder-cup types,
enabling wiring configurations tailored to your equipment setup.
◆ A wide range of tip shapes, diameters, spring forces, and materials is available,
accommodating diverse test points such as terminals, busbars, and battery tabs.
◆ Contact stability is maintained even with repeated use,
ensuring highly reproducible measurements during long-duration or high-cycle testing processes like aging and formation.
◆ The standard lineup covers rated currents from 20A to 400A,
allowing for the optimal choice based on specific application requirements.
