Solutions for individual requirements!
Innovative safety relays
The safety relays OA5621 and OA5622 of DOLD are designed for up to 8 A continuous current and various contact arrangements. The user can not only choose between different contact materials and contact designs, but also a number of mixed arrangements is possible. Therefore the safety relays can be easily adapted to individual requirements.
Contacts are available with the materials AgNi, AgSnO2 and gold plating as well as single or twin contacts for each contact pair.
AgNi is he material for standard applications and is used for single contacts. For high loads e.g. to switch inductive loads AgSnO2 is the preferred material also on single contacts. In the case very small loads have to be switched gold plated contacts should be used that have higher switching reliability due to reduced contact resistance.
Gold plated contacts are available as single contacts e.g. as feed back contacts in controls and as twin contacts for applications with special requirements. The twin contacts with mini crown increase the high contact reliability by the principle of redundancy.
The dimensions of the relays are 46 and 55x22x15,5mm.
