It is a relay enclosed in a sealed housing designed to protect its internal switching components from moisture, dust, gases, and other environmental contaminants.

The image shows several different relay models, so there is no single voltage rating that can be reliably assigned to the entire product range. Coil voltage should be specified according to the individual model or datasheet.

Their sealed construction helps protect sensitive internal components from environmental exposure, supporting reliable operation in challenging conditions.

Yes. Several of the pictured models feature pins suitable for mounting on compatible printed circuit boards.

They are commonly used in aerospace, defense, telecommunications, instrumentation, industrial control, test equipment, and other applications requiring dependable electrical switching.
