2. Specifications

Notes: *1 This value can change due to the switching frequency, environmental conditions, and desired reliability level, therefore it is recommended to check this with the

actual load. (AgPd contact type is available for low level load switching [10V DC, 10mA max. level])

*2 The upper operation ambient temperature limit is the maximum temperature that can satisfy the coil temperature rise value. Refer to [6] AMBIENT ENVIRONMENT

in GENERAL APPLICATION GUIDELINES (Page 24).
