SICK i110 Safety Switch, Die Cast Zinc

This safety switch is an electromechanical interlock designed for industrial safety applications where a robust, sealed switching device is required. It provides positive-action contacts and is intended for connection to a safety-related control unit for fault monitoring. The unit is supplied without an actuator and is suitable for environments that need a sealed enclosure and a wide ambient temperature capability.

• 3A contact current delivers defined low-voltage switching capability
• IP67 enclosure rating allows washdown and dusty-environment use
• Die-cast zinc housing offers mechanical protection and stability
• Five head directions enable flexible actuation orientation
• Positive-action contacts provide predictable safety switching behaviour

• Suitable for guarding on production machinery requiring sealed switches
• Ideal for assembly lines with limited actuator availability
• Used for access interlocks where variable head alignment is needed
• Can be used for installations operating between -20°C and 80°C
• Suitable for systems requiring series type 2 safety wiring

It connects via a single M20 cable gland and accepts conductors up to 1.5mm².

The device contains three normally closed positive-action contacts and one normally open contact.

The mechanical B10d rating is 2x10⁶ switching cycles for small-load applications.

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

It is specified for 3A at 24V AC and 2A at 24V DC with a minimum switching threshold of 5V DC at 5mA.
