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 interrupting circuits when guards are opened. It is intended for industrial installations requiring a compact, sealed switch with multi-direction actuation and straightforward wiring into safety circuits. The unit is supplied without an actuator and operates across common control voltages while relying on external safety logic for fault monitoring.

• 2NC 1NO contacts provide positive-action switching and diagnostics
• 3A rated operating current supports 240V AC and 24V DC loads
• IP67 enclosure rating enables use in dust-tight and wet conditions
• Fibreglass reinforced thermoplastic housing offers Durable mechanical protection
• Operates between -20°C and +80°C for high-temperature environments

• Used for safeguarding machine access hatches and doors
• Suitable for integration with safety logic units in production lines
• Ideal for multi-directional guard monitoring on conveyors
• Used with control panels requiring slow-action switching elements
• Suitable for installations demanding Compact sealed switches

It employs slow-action switching elements with positive-action contacts for controlled circuit interruption.

Connections are MADE via a single M16 cable gland accepting conductors up to 1.5mm² cross-section.

The switch lacks internal fault detection

The device has a B10d Value of 2x10⁶ switching cycles for small-load applications.

The head can be oriented in five directions to accommodate various actuator approach angles.
