Introduction: Panasonic relay SF has a safety mechanism that allows it to reliably stop the next operation even when it is affected by overload and circuit abnormalities (faults and faults caused by sudden external factors such as interference, surges, and environments), contact adhesion and spring blowing, or unexpected electrical connection faults (coil disconnection, poor operation, poor reset, and fatigue and damage of action springs and return springs) and when the life limit is reached. Or by its own ability to reset it to a safety device.
Features:
Forced-drive mode
A and B contacts are maintained with a card, and each other is forced to drive. When a contact is sticked, it is possible to ensure that the gap between the other contacts reaches 0.5 mm, stop the next movement, and detect the sticking.
Isolation chamber method
Cards and isolators are used to separate the contacts and place them in a separate space to prevent short circuits between the poles.
3A1B contact configuration
Various control circuits can be formed.
High withstand pressure
It has a high withstand voltage of up to 2,500 V AC. (between contacts, between contacts and coils)
High sensitivity
The high-efficiency pole magnetic circuit using a 4-gap balanced armature is used as a power type relay to achieve unprecedented ultra-thin and high sensitivity (rated power consumption of 500 mW).
