SICK I12 Safety Interlock Switch, Fibreglass Reinforced Thermoplastic

This safety interlock switch is an electro-mechanical device designed to monitor access points and protect machinery by detecting actuator position. It is intended for industrial environments where a compact, sealed switch is required and connects via a single M16 cable gland. The unit operates across a broad ambient temperature range and is suitable for wiring into safety-related logic units that perform fault detection.

• IP67 enclosure rating provides protection against dust and immersion
• 3A switching capacity supports 240V AC and 24V DC circuits
• Five approach directions enable flexible actuator alignment
• Fibreglass-reinforced thermoplastic housing offers mechanical durability
• Slow-action switching ensures defined contact behaviour during cycles

• Suitable for guarding access panels on production lines
• Used with safety logic units for fault‑monitored interlocks
• Ideal for conveyor isolation points requiring Compact switches
• Can be used for machine doors needing multi‑direction actuation

It can switch up to 3A at 240V AC and 2A at 24V DC with a minimum switching voltage of 5V DC.

The unit provides a single cable‑gland entry (1x M16) and accepts conductors up to 1.5mm².

The switch contains no internal fault detection and relies on the connected safety logic unit for fault monitoring.

Mechanical life is specified at 1x10⁶ switching cycles with an electrical B10d of 2x10⁶ switching cycles under small load.

It operates and can be stored between -20°C and +80°C and is rated to IEC 60529 for IP67 protection.
