(Not freezing and condensing at low temperature) Conditions Max. operating speed 6 cpm (at nominal switching capacity) Mass Twin type: approx. 8 g .28 oz, 1 Form C type: approx. 4 g .14 oz 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. *2. The upper operation ambient temperature limit is the maximum temperature that can satisfy the coil temperature rise value. Please refer to Usage ambient condition in CAUTIONS FOR USE OF AUTOMOTIVE RELAYS. Please inquire if you will be using the relay in a high temperature atmosphere (110C 230F). *3. Depends on connection conditions. Also, this does not guarantee repeated switching. We recommend that you conrm operation under actual conditions. If the relay is used continuously for long periods of time with coils on both sides in an energized condition, breakdown might occur due to abnormal heating depending on the carrying condition. Therefore, please inquire when using with a circuit that causes an energized condition on both sides simultaneously. REFERENCE DATA 1-(1). Coil temperature rise (at room 1-(2).
