To protect from dust, these types are covered, for example, with a plastic case. We recommend hand soldering, because these relays are not constructed to prevent flux and cleaning fluid from entering during automatic soldering.
The relay is constructed so that flux will not enter inside the relay during automatic soldering. However, cleaning is not possible.
Construction is designed to prevent seeping of flux when soldering and cleaning fluid when cleaning. Designed for minimal release of harmful gas at the contacts.
This type is hermetically sealed with ceramic and metal plating. No harmful gas or humidity will ever reach the contacts. This type cannot be washed.
|Dust Cover Type||Most basic construction where the case and base (or body) are fitted together.||Caution||No||Caution||No|
|Flux-Resistant Type||Terminals are sealed or molded simultaneously. The joint between the case and base is higher than the surface of the PC board.||Yes||No||Caution||No|
|Terminals, case and base are filled with sealing resin.
Construction is not hermetically sealed.
|Sealed Type||Sealed construction including terminals and case. The base is sealed with sealing resin.||Yes||Yes||Yes||Yes|
|Sealed Capsule Type (EP and EV relays only)||Hermetically sealed construction by sealing the metal case and plate, and the terminal and ceramic part, with solder.||No||No||Yes||Yes|
Since the plastic material is porous, please avoid atmospheric exposure to silicon..
Relay which turns on when the coil is energized and turns off when deenergized.
Relay with latching construction that can maintain the on or off state with a pulse input. With one coil, the relay is set or reset by applying signals of opposite polarities.
Relay with latching construction composed of 2 coils: set coil and reset coil. The relay is set or reset by alternately applying pulse signals of the same polarity.
Indicates the set and reset states (electrically or mechanically) for easy maintenance. Also available are an LED version (HC relay with LED).
Sockets are available for certain PC board relays. (S relay, ST relay, etc.)
