Locking Style Safety Interlock Switches
Guard locking safety switches include a machine mounted switch and a guard mounted actuator that prevent access to an area by remaining locked together until the hazardous motion has come to a complete stop.
- Mechanically coded actuators use two independent operating elements, making it difficult to bypass safety functions
- Rotating head requires little or no tools to adjust to one of four positions
- Can be used to prevent access to a hazard, ensure critical processes are not interrupted, or secure material and equipment from theft or tampering
- Once locked, a machine guard door will not open, eliminating an opportunity for nuisance trips, even if exposed to frequent impact or prolonged vibration
- IP67-rated safety devices that resist dust, dirt, and some exposure to water and similar environmental challenges
- Design meets positive opening requirements for safety interlocks
- Available in power-to-lock and power-to-unlock models with rigid and flexible in-line actuators and a wide range of solenoid voltages

Verriegelungsschalter
Bauform SI-LS42
Schutzsperrsicherheitsschalter beinhalten einen maschinenmontierten Schalter und ein schutzgelagertes Auslösegerät, die den Zugang zu einem Bereich verhindern, indem sie miteinander verbunden bleiben, bis die gefährliche Bewegung vollständig zum Stillstand gekommen ist.
- Erreicht die Sicherheitsstufen Cat 4, PL e oder SIL CL 3 mit einem einzigen Schalter, der auf einer Schutzeinrichtung eingesetzt wird
- Mechanisch codierte Auslösegeräte verwenden zwei unabhängige Bedienelemente, was es schwierig macht, Sicherheitsfunktionen zu umgehen
- Drehkopf erfordert wenig oder gar kein Werkzeug für die Einstellung einer der vier Positionen
- Kann verwendet werden, um den Zugang zu einer Gefahr zu verhindern, kritische Prozesse nicht zu unterbrechen oder Material und Ausrüstung vor Diebstahl oder Manipulation zu schützen
- Nach dem Verriegeln öffnet sich eine Maschinenschutztür nicht mehr und es besteht keine Möglichkeit für störende Auslösungen, auch wenn sie häufigen Stößen oder längeren Vibrationen ausgesetzt sind
- IP67-konforme Sicherheitseinrichtungen, die Staub, Schmutz und Wasser und ähnlichen Umwelteinflüssen widerstehen
- Design erfüllt die Anforderungen für Sicherheitsschalter mit Zwangsöffnung
- Erhältlich in Power-to-Lock- und Power-to-Unlock-Ausführungen mit starren und flexiblen Inline-Auslösegeräten und einem breiten Spektrum von Magnetspannungen.
