High Voltage Reed Relays

Introduction

GUNTHER^© High Voltage Reed Relay technology is based upon our extensive experience in the design and manufacture of reed switches and reed relays.

GUNTHER^© High Voltage Reed Relays have outstanding performance characteristics in insulation resistance and stand-off voltage. The high dielectric stand-off voltage between the open contacts as well as the high switching voltage are achieved by using high vacuum Reed Switches. A proven assembly and potting technique assures the following relay characteristics:

• Stand-off voltage across open contacts from 3 kV up to 14 kV max.
• Stand-off voltage between coil and contact from 10 kV up to 25 kV max.
• Switching voltage from 1.5 kV up to 10 kV max.

Contact Configuration

GUNTHER^© High Voltage Reed Relays are offered in a variety of contact configurations:

• 1 N.O., 2 N.O. or 4 N.O. contacts (normally open contacts)
• 1 N.C. (normally closed contact)
• 1 N.C. / 1 N.O. (1 normally closed contact / 1 normally open contact)

Mounting Flexibility

GUNTHER^© High Voltage Reed Relays offer mounting flexibility enabling the customer to match different application requirements:

• Coil and Reed Switch connecting pins in the base plate for PCB mounting.
• Coil connecting pins in the base plate for PCB mounting and Reed Switch connections with cable.
• Coil connecting pins in the base plate for PCB mounting and Reed Switch connecting pins on top of the relay.

Additional features

GUNTHER^© High Voltage Reed Relays hav additional features:

• Immunity against harsh environmental conditions (eg. high humidity) by using hermetically sealed switching contacts potted in a strong plastic case.
• High shockand vibration resistance.
• Low contact capacitance and high switching frequency in comparison with electromechanical, open relay contacts.
• Washable and resistant to standard automatic cleaning methods.

Industry Application

GUNTHER^© High Voltage Reed Relays find application in many areas of the electrotechnical and electronic industry:

• Electronic medical equipment
• Cable tester arrays and cable test equipment
• Copy machines
• Laser optical systems and infra-red equipment
• Test equipment
