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. 

Form A (energize to make) and Form B (energize to break) configurations are available with appropriate control circuitry to ensure break before make for operate and release. It is usually possible to achieve a Form C (change-over) function by using Form A and Form B types together. However, a 1 Form C, up to 5 kV, is available within the Series 67 range. 

These relays feature internal mu-metal magnetic screens which permits Form A (energize to make) versions to be mounted side by side. Special versions can be manufactured with an electrostatic screen and/or earth connection to the magnetic screen where EMC problems may be encountered. Please contact our technical sales office for more information and advice. 

Form B types are magnetically biased and should not be mounted directly onto ferrous metal chassis or less than 1 inch (25 mm) 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, the positive connection is identified by a red spot.

## Note[1] : Switching Voltage 

Voltage rating is for RESISTIVE loads only. At higher voltages stray capacitance can generate large current pulses, potentially damaging the contact plating and causing switch welding. Capacitive circuits require provision to limit the surge to within the current and power ratings of the relay. 

## Note[2] : Life Expectancy 

Relay life depends upon switch load and end of life criteria. For an end of life contact resistance specification of 1 Ω, switching low loads with a current less than 1 mA, typical life is expected to be greater than 1 x 10[8] ops. At higher voltages up to a maximum 50 W resistive load, typical life is 1 x 10[6] ops. In abusive conditions (e.g. high capacitive inrush current) this figure reduces considerably. Pickering can perform life testing with any load conditions.

## **Operating Voltages** 

|Coil voltage - nominal|Must operate voltage - maximum at 25 °C|Must release voltage - minimum at 25 °C|
|---|---|---|
|5 V|3.75 V|0.5 V|
|12 V|9 V|1.2 V|
|24 V|18 V|2.4 V|



## **Environmental Specification/Mechanical Characteristics** 

In the table below, the upper temperature limit can be extended to +125 °C if the coil drive voltage is increased to accommodate the resistance/temperature coefficient of the copper coil winding. This is approximately 0.4% per °C. This means that at 125 °C the coil drive voltage will need to be increased by approximately 40 x 0.4 =16% to maintain the required magnetic drive level. Please contact  sales@pickeringrelay.com  for assistance.
