Design
Enclosure sizes
The 3SE5 switches are available as complete units in two enclosure sizes:
- Plastic enclosures according to EN 50047, 31 mm wide, IP65, 1 cable entry
- Metal enclosure according to EN 50047, 31 mm wide, IP66/IP67, 1 cable entry
- Plastic and metal enclosures according to EN 50041, 40 mm wide, IP66/IP67, 1 cable entry
Enclosure versions
Various basic versions can be selected for the enclosures:
For a description of the basic switches, see SIRIUS 3SE5 mechanical position switches.
Operating mechanism
The hinge switches are provided for mounting on hinges. The actuator head is included in the scope of supply. There are two versions:
- Actuator with hollow shaft, inner diameter 8 mm, outer 12 mm
- Actuator with solid shaft, diameter 10 mm
3SE2283 hinge switches
The 3SE2283 hinge switches with integrated hinge can be ordered as a special design. They are particularly suitable for use in machine doors and flaps.
ENG_119355.XML
The hinge switches are used in those areas where the position of swiveling protective devices such as doors or flaps must be monitored. With these switches, the position of the doors and flaps is converted into electric signals. The switches allow shutdown and signaling without delay in the event of a small opening angle through the snap-action contacts with an actuating angle of 10°.
Devices are available with enclosure versions to suit the particular ambient conditions. Different control tasks can be performed with the contact blocks best suited for the particular purpose. Dimensions and fixing points of the enclosures are according to EN 50041 or EN 50047 standards.
The devices are suitable for use in any climate.
Standards
The switches comply with IEC 60947‑5‑1 (Electromechanical Control Circuit Devices).
The protective measure of "total insulation" by the plastic enclosure is ensured by the use of plastic screw glands.
Safety position switches
For controls according to IEC 60204-1, the devices can be used as a safety position switch. To secure position switches against changes in their position, positively-driven techniques must be employed on installation.
Safety circuits
Standard IEC 60947‑5‑1 requires positive opening of the NC contacts. In other words, for the purposes of personal safety, the assured opening of NC contacts is expressly stipulated for the electrical equipment of machines in all safety circuits and marked according to IEC 60947‑5‑1 with the symbol (→).
SIL 2 according to IEC 62061/IEC 61508 or PL d according to ISO 13849‑1 can be attained with a 3SE5 safety hinge switch with (→) if the corresponding fail-safe evaluation units are selected and correctly installed (e.g. the 3SK safety relays or matching units from the ASIsafe, SIMATIC or SINUMERIK product ranges).
If a second 3SE5 position switch with (→) is used, SIL 3/PL e can be attained.
Evaluation of safety functions
Safety Evaluation in the TIA Selection Tool
The safety evaluation for the IEC 62061 and ISO 13849-1 standards is performed quickly and easily, directly in the TIA Selection Tool. In addition to the fast and safe calculation of machine safety functions – from the definition of the system structure to the selection of components – this enables shared data management during all project phases. Take the next step in the digital design of machinery and equipment with Safety Evaluation in the TIA Selection Tool.
In addition, the functionalities of the proven Safety Evaluation Tool are still available. It determines the achieved safety integrity (SIL/PL) step-by-step. You receive the results as a standards-compliant report that can be integrated in the documentation as proof of safety.
