Safety relays OA 5642 ...
with positively guided contacts only 10.3 mm high
In many safety-related applications where relays with positively guided contacts
(as per EN50205) are used special attention is paid to a compact design, apart from
the high switching reliability. With the new safety relays OA 5642, OA 5643 and
OA 5644 DOLD provides an extremely flat relay range setting new standards.
Only 10.3 mm in height, these 2-, 3- and 4-pole relays are among the flattest safety
relays on the market. They are ideal for the realisation of compact safety switching
devices (only 15 mm in width) and for applications where little space in height is
available. Besides compactness, the design of the relays also allows an arrangement
of SMD components between board and relay.
For applications where the power consumption is critical, energy saving was
particularly taken into account by nominal power values of only 0.4 W, 0.5 W and
0.65 W and a lowering of the holding power to about a third of the pickup power.
The relay, which is wash-tight (RT III) and temperature-stable up to 85 °C in its
standard version, can be especially well processed in leadfree solder processes.
