DOLD safety relays for through-hole mounting, available from ELTRON, are proven and highly reliable components for systems requiring a high level of functional safety. They are designed for industrial applications, automation, control, railway and security systems, where stable and long-term operation of the device is crucial.

Depending on the design requirements, the relays are available in various configurations: from 2 to 8 contacts, with a nominal voltage range of 5–110 V and a load capacity of up to 10 A. The compact design (from 10.3 mm to 39.2 mm in height) allows for use even in densely populated electronic systems.

Some models, such as the OA 5611/___S and OA 5622_D, offer increased sensitivity or gold-plated contacts, making them ideal for low-signal applications and in high-reliability environments, such as railway applications or security systems.

DOLD also offers dedicated mounting bases for each model, allowing both through-hole mounting and DIN rail mounting for complete design flexibility. LED function modules with signalling and protection are also available, compatible with the OA 5669 relay, among others.
