Overview
3SE66 contact blocks and 3SE67 switching magnets
A magnetically operated switch comprises a coded switching
magnet and a contact block (sensor unit). The switch must be
connected to a safety relay, e.g. SIRIUS 3SK1, or a bus system,
e.g. SIMATIC ET 200SP, for evaluation. The switches use reed
contacts as mechanical contacts. The status of the contacts is
monitored using an evaluation unit.

Safety relays
3SK safety relays can be used worldwide since they possess all
the required certification. Since they satisfy the most exacting
safety requirements, they are suitable for all kinds of safety
applications.
The following can be selected:
•
3SK1 Standard basic units:
simple and compact to satisfy all the essential requirements of
safety sensor monitoring systems
•
3SK1 Advanced basic units:
multifunctional series with relay enabling circuits,
semiconductor outputs or time-delay outputs
•
3SK2 basic units:
multifunctional series whose functionality is parameterized
using software. The basic units have solid-state outputs. Relay
输出从3 sk1组合也可以connected via
device connectors.
•
Expansion units for inputs and outputs
The 3SE6806 safety relay is also available with two floating
enabling circuits (safe circuits) as NO contact circuits and one
floating signaling circuit as an NC contact circuit.
