High-voltage signal routing
Use reed relays to route high-voltage test signals between an HV source, measurement instrument and device under test without building a large mechanical switching assembly.
10kV HV Reed Relay
10kV Reed Relays for High-Voltage Test Paths
SHR AUTOSENSOR 10kV reed relay solutions are intended for guarded high-voltage test, insulation measurement and equipment validation paths where compact size, low leakage and repeatable operation matter.

What this component is used for
Compact PCB or fixture integration
Compared with many power switching devices, HV reed relays can fit into dense test fixtures when clearance, creepage and guarding are designed correctly.
Repeatable measurement support
Low leakage and stable insulation are important for insulation resistance, leakage current and parametric measurements.
Application details
Hipot and insulation resistance testers
Switch test voltage between multiple DUT pins, cable conductors or fixture channels while keeping unselected paths isolated.
Semiconductor and component test
Route high-voltage stress or measurement channels in wafer probe, package test and characterization fixtures.
Medical and industrial equipment validation
Support production test systems for high-voltage modules, power supplies and safety-related assemblies.
Custom fixtures
Use as part of multi-channel switching banks where channel spacing, guarding and wiring layout are engineered together.
Representative 10 kV-class series: HVR
The HVR family is the standard 10 kV-class high-voltage reed relay line for these paths. The figures below are representative of the series; exact ratings vary by part number and are confirmed against the datasheet during design-in.
| Max contact rating | 50 W |
| Max switching voltage | 7.5 kVDC |
| Min breakdown voltage | 10 kVDC (15 kVDC grade) |
| Dielectric, coil/contact | 15 kVDC |
| Switching / carrying current | 3 A / 5 A |
| Max contact resistance | ≤150 mΩ |
| Insulation, coil/contact | 1×1012 Ω |
| Capacitance across contacts | 0.8 pF |
| Operate time, incl. bounce | 3 ms |
| Operating / storage temperature | -20…+70 °C / -35…+105 °C |
Reading the model code
HVR = family; first two digits = coil voltage (05 = 5 VDC, 12 = 12 VDC, 24 = 24 VDC); contact block = form (1A normally open, 1B normally closed) and breakdown grade (10 = 10 kV, 15 = 15 kV); suffix (04 / 06 / 150) = pin/terminal option. Representative parts: HVR05-1A10-04, HVR12-1A10-06, HVR24-1A10-150.
Selection factors engineers should confirm
- Confirm switching voltage separately from stand-off or isolation voltage.
- Check load type: resistive, capacitive, cable, charged capacitor or hot-switching profile.
- Review leakage current, insulation resistance and contact resistance requirements.
- Design PCB clearance/creepage, guarding and contamination control for the working voltage.
- Select coil voltage, contact form, package, termination and expected switching life from the datasheet.
Engineering note: Do not assume a relay can hot-switch the maximum stand-off voltage. Final rating depends on load profile, current, capacitance and life target.
