Shop hermetically sealed relays for electrical switching and control in demanding industrial environments. Their sealed construction helps protect internal contacts and operating components from moisture, dust, gases and other environmental contaminants.
Wallco supplies hermetically sealed relays from established manufacturers in a range of coil voltages, contact configurations, current ratings, terminal arrangements and mounting styles. Use the available technical filters to compare products and identify a relay suited to your equipment and operating environment.
Hermetically sealed relays are designed with a sealed enclosure that limits exposure of the internal switching mechanism to moisture, dust, gases and other contaminants. They are commonly used in industrial equipment, transportation systems, process controls and other applications where environmental protection and dependable operation are important.
Important selection factors include coil voltage, contact configuration, contact current and voltage ratings, number of poles, terminal or pin arrangement, mounting method and environmental approvals. Products described as sealed, hermetically sealed or suitable for hazardous locations may have different ratings and certifications, so the manufacturer’s specifications should be reviewed carefully.
Products are organized generically so sealed relays from different manufacturers can be reviewed within the same category and technical filters.
