GÜNTHER High Voltage Reed Relay technology is based upon our extensive experience in the design and manufacture of Reed Switches and Reed Relays.
GÜNTHER 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.
GÜNTHER 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)
GÜNTHER 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
GÜNTHER High Voltage Reed Relays have additional features:
Immunity against harsh environmental conditions (e.g. high humidity) by using hermetically sealed switching contacts potted in a strong plastic case
High shock and vibration resistance
Low contact capacitance and high switching frequency in comparison with electro-mechanical open relay contacts
Washable and resistant to standard automatic cleaning methods
GÜNTHER 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

General Parameters

All characteristics for pull-in voltage, drop-out voltage and coil resistance at 20°C+/-3°C ambient temperature. For other temperatures see diagram temperature range.

Contact Resistance

Initial value at nominal voltage measured by the Kelvin test method at 20V/100mA.

Soldering

During soldering make sure no mechanical stress to be applied to terminals because the thermoplastic molding material might be damaged .

Order Example:

                         33    92   1270   05  6

Product group      Contact code    Standard type     Nominal coil voltage

05= 5V   12=12V   24 = 24V

Insulation Resistance

The insulation resistance is measured with a Tera Ohmmeter at 500V DC. The ambient climate is 20°C +/-3°C and 50 % relative humidity.
