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.
*2. The upper limit of the ambient temperature is the maximum temperature that can satisfy the coil temperature rise value. Refer to Usage, transport and storage
conditions in NOTES.
*3. According to EN 61810-1:2010, table 2. Characteristic is sealed construction with terminals, case and base sealed shut with sealing resin. Construction is
designed to prevent seeping of flux when soldering and cleaning fluid when cleaning. Harmful substances on the contacts are removed by gas purging before
sealing with.
*4. Coil holding voltage is the coil voltage after 100 ms from the applied nominal voltage.
Important: Relay characteristics may be influenced by:
• strong external magnetic fields
• magnetic conductive materials near the relay
• narrow top-to-top mounting (printed surface to printed surface)
Insulation
