Safety Solenoid Switches
🔐 Key‑Operated Solenoid Safety Switches
Telemecanique key‑operated solenoid interlock switches
secure access to hazardous machine areas by electrically locking guards
and requiring a physical key
for authorised entry.
They ensure a machine cannot run with the guard open
and the guard cannot open while the machine is running.
🟦 Core Functions
- Electromagnetic locking — guard stays locked until the machine reaches a safe state
- Key‑based access — only authorised personnel can unlock/open
- Interlocking logic — prevents the machine from starting when the guard is open
🟧 Key Characteristics
- Robust industrial construction — built for harsh, high‑duty environments
- Safety‑standard compliance — ISO 13849, IEC 62061
- Flexible mounting options — fits doors, hatches, sliding guards
- Status indication — some models include LED lock/unlock indicators
🟨 Typical Applications
- Manufacturing cells — robots, presses, assembly lines
- Food processing — high‑temperature and moving‑blade zones
- Packaging machines — high‑speed mechanisms
- Pharmaceutical lines — hazardous substances and enclosed systems
- Automotive production — heavy machinery and robotic arms
🟩 Benefits
- Enhanced operator safety — prevents accidental start‑up
- Controlled access — key ensures authorised entry only
- Operational reliability — reduces downtime from unsafe conditions
- Regulatory compliance — supports PL e / SIL 3 architectures
⭐ One‑line summary
Telemecanique key‑operated solenoid switches lock guards electrically and require a key for authorised access, ensuring safe, compliant entry into hazardous machine zones.
