Series Features
BH Series Reed Relay
Series DescriptionThe BH Series is a high-power, high-insulation reed relay engineered for precision switching in demanding test and measurement environments. Capable of switching up to 1 kVDC with a breakdown voltage of 3 kVDC and above, the BH Series offers ultra-low leakage current in the picoampere range and insulation resistance up to 10 TΩ, making it ideal for high-voltage and high-accuracy applications.
Designed with an integrated electrostatic shield and axial switch leads, the BH Series ensures minimal interference and high-density assembly. Available in SPST-NO (Form A) configurations with up to 4 switches per relay, it supports coil voltages of 5 VDC, 12 VDC, and 24 VDC, and rated power up to 100 W. Its robust dry-switch design and magnetic shielding make it a reliable alternative to mercury wetted relays in automated test equipment and semiconductor testing.
- High switching voltage capability up to 1 kVDC
- Breakdown voltage of 3 kVDC and higher across open contacts
- High insulation resistance up to 10 TΩ for ultra-low leakage current
- Multi-channel dry-switch design with up to 4 Form A switches
- Integrated electrostatic shield for enhanced isolation
- Magnetic shielding for high-density PCB assembly
- Low contact resistance (ON-resistance) for reliable signal integrity
- Through-hole mounting for secure and stable integration
- RoHS and REACH compliant for global environmental standards
