SICK i110 Safety Switch, Power, Die Cast Zinc

This safety switch is an electro-mechanical power lock device designed to monitor access to guards and hazardous openings in industrial settings. It provides a slow-action switching element with a combination of normally closed and normally open contacts and is intended for individual wiring with diagnostics performed by external safety logic. The unit is built for outdoor or wash-down environments where an IP66 enclosure rating and a die-cast zinc housing are required.

• 3A contact current delivers safe switching at industrial voltages
• 240V AC and 24V DC support common control voltages
• Two head directions enable flexible actuator orientation
• Positive-action N/C contacts improve fault-tolerant response
• Temperature range -25°C to 80°C allows wide ambient use

• Suitable for machine guarding interlocks in manufacturing plants
• Ideal for conveyor access gate monitoring with diagnostics
• Used with safety PLCs requiring slow-action switching elements
• Can be used for outdoor enclosures requiring weatherproof protection
• Appropriate for individually wired safety circuits in non-hazardous areas

It provides two positive-action normally closed contacts and one normally open contact.

Use a 3A gG fuse or equivalent short-circuit protection sized to the rated insulation and switching current.

A single M20 cable gland is used with conductors up to 1.5mm² cross-section.

The mechanical life is rated at 1x10^6 switching cycles under specified conditions.
