Miniature Signal Relays – EA2/EB2

Contact Specifications

*1

 This value is a reference value in the resistance load. Minimum capacity changes depending on the switching frequency, environment temperature,       

and load.

*2

 Rise time: 10 µs; decay time to half crest: 160 µs.

*3

 This shows the number of operations with fatal defects. Stable characteristics are maintained for 1 x 10

7

 operations.
