Series 60 Chassis mounting with solder connections on the top face.
Series 65 Printed circuit mounting.
The Series 60 and 65 ranges of high-voltage reed relays have been manufactured for many years and remain popular due to their small size and ease of use.
They are available for up to 15kV stand-off, 12.5kV switching at 50 Watts maximum. Tungsten plated contacts ensure a long and reliable life.
Both Form A (energise to make) and Form B (energise to break) configurations are available, and it is usually possible to achieve a Form C (change-over) function by using a Form A and a Form B type together.
Form B types are magnetically biased and should not be mounted directly onto ferrous metal chassis, or less than 1.5 inches (38mm) away from other relays as the coil operating voltage characteristics will be altered due to magnetic interaction. The coils of Form B relays are polarity sensitive; a red spot identifies the positive connection.
Form A types can be mounted on ferrous chassis, but 1 inch (25mm) should be allowed between adjacent relays. 5, 12, and 24 volt coils are available as standard. Other voltages are open to a particular order. Please get in touch with our sales office.
If similar relays with “push-on” connectors are preferred, please look at our Series 62 and Series 63.

The Series 62 and 63 ranges of high voltage reed relays feature push-on terminals and are supplied complete with the appropriate connectors and insulating boots.
They are available for up to 15kV stand-off, 12.5kV switching at 50 Watts maximum. Tungsten plated contacts ensure a long and reliable life.
Both Form A (energise to make) and Form B (energise to break) configurations are available and it is usually possible to achieve a Form C (change-over) function by using a Form A and a Form B type together.
These relays feature an internal mu-metal magnetic screen which permits the Form A (energise to make) versions to be mounted side by side. Special arrangements can be manufactured with an electrostatic screen and earth connection to the magnetic screen. This can often be useful where EMC problems are encountered. Please get in touch with our technical sales office.
Form B types are magnetically biased and should not be mounted directly onto ferrous metal chassis or less than 1 inch (25mm) away from other relays as the coil operating voltage characteristics will be altered due to magnetic interaction. The coils of Form B relays are polarity sensitive. A red spot identifies the positive connection.
5, 12, and 24 volt coils are available as standard other voltages can be supplied to special order.

Series 68 PCB contains connections on the underside for coil connections. Flying leads from the top face for high voltage connections.
Series 67 and 68 contain former-less coils. The absence of a coil supporting bobbin allows a device smaller than the industry norm. The unusual package design gives some exciting possibilities for high-density packing.
The option of flying leads for the high voltage connections makes it possible to keep this away from lower voltage circuitry on the PCB.
Form A (energise to make) and Form C SPDT (changeover) contacts are available with the option of 5, 12 and 24 volt operating coils.

- Many benefits compared to industry standard relays. Learn more here >.
The Pickering Series 100HV have the exact High Voltage specifications as the Pickering Series 104 but with over double the coil resistance. They are ideal for such applications as a transformer or cable testing or any other automatic test equipment where high voltages are involved, and low coil power consumption is required.
Where mains voltage is switched, for example, to control and isolate S.C.R. or Triac gates, they are an ideal choice. And in mixed-signal applications, the lower coil power reduces the Thermal EMF voltages generated across the switch. 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 dry switches are available, capable of standing-off 1.5, 2 or 3 kV d.c. The 3 kV version has an increased clearance between the switch and coil pins to accommodate the higher voltage. Even higher voltage ratings are available to a particular order, please content our sales office for further information.

Six versions are available, all with either 3, 5 or 12 volt operating coils. The 1 Form A, 1.5kV version has a package and pin configuration compatible with the standard 109P type, i.e. four pins on 0.15 inches (3.8mm) pitch. The other classes have package lengths and pin configurations appropriate for their voltage ratings, and the user will need to arrange suitable clearance distances around the parts.
Form A types can be mounted side by side. Still, a 1cm space should be left between the Form B type and other relays, as the magnetic field from the internal biasing magnet could slightly affect the sensitivity of the relay alongside.
