Minimum breakdown voltage of 1200Vdc
Available sensitivity range of 50-80 AT

Benefits:

Hermetically sealed switch contacts are not affected by and have no effect on their external environment
Can be used as changeover or normally closed contact
Capable of switching global mains voltage
Zero operating power required for contact closure

Applications:

Security
Limit switching
Industrial safety
White goods
