Please see below Pickering’s Series 104 high voltage reed relays.
These relays can stand-off 3kV, switching at up to 25W.
Series 104 reed relays are suitable for many applications including mixed signal semiconductor testers, high-end cable testers, backplane testers, medical electronics, electric vehicles, solar energy and high voltage instrumentation.
High Voltage SIL / SIP Reed Relays
For up to 3 kilovolts
• SoftCenter™ construction
• Highest quality instrumentation grade reed switches
• Small size HV reed relay
• Internal mu-metal magnetic screen
• One or two reed switches in a single package
• Many benefits compared to industry standard relays. Learn more here >.
• Form A (energize to make) or Form B (energize to break) configurations
• Dry and mercury wetted reed switches available
• 5, 12 and 24 Volt coils are standard, with or without internal diode
• 100% tested for dynamic contact resistance
The Series 104 is a range of Single-In-Line reed relays intended for voltages that are beyond the capabilities of conventional SIL reed relays.
They are ideal for such applications as transformer or cable testing or any other automatic test equipment where high voltages are involved.
Where mains voltages are switched, for example to control and isolate S.C.R. or triac gates, these reed relays are an ideal choice.
One or two Form A (energize to make) or one Form B (energize to break) configurations are available.
The range features an internal mu-metal screen to eliminate problems that would otherwise be experienced due to magnetic interaction when they are closely stacked.
Three types of dry switches are available, capable of standing-off 1, 1.5 or 3kV d.c. The 3kV version has an increased clearance between the switch and coil pins to accommodate the higher voltage. Even higher voltage ratings are available to special order, please contact our sales office for further information.
Mercury wetted devices are also available for applications where bounce free switching is required. These are rated at 1500 volts d.c. minimum stand-off, 500 volts d.c. switching at up to 50 watts.
