SICK i110 Series Safety Switch, 190mm Length, IP67 - i110-M0233

This safety switch is an electro‑mechanical interlock designed to secure movable guards in industrial settings. It employs a power‑to‑release locking principle with positive‑action monitoring contacts to supervise lock and door states. The unit is housed in glass‑fibre reinforced thermoplastic for protection against contaminants and is intended for individual wiring with diagnostic‑capable logic units. The device operates across a wide ambient range and is rated for use where ingress protection to IP67 is required.

Features and Benefits:

• 2NC safety contacts provide monitored locking at 4A current
• Power‑to‑release lock ensures controlled retention during power application
• Five head directions allow flexible actuator approach
• Contamination rating 3 supports operation in dirty environments
• Rated insulation voltage 250V provides electrical separation for controls

Applications

• Suitable for guarding on automated production machinery
• Ideal for safety interlocks on access doors in conveyors
• Used with diagnostic safety logic for monitored installations
• Can be used for machine perimeter protection in factories
• Used for retrofit safety upgrades requiring IP67 protection

What electrical ratings should be considered for wiring?

The contacts are rated 4A at 230V AC and 4A at 24V DC with Ui 250V and Uimp 1,500V.

How is the device connected electrically?

Connections are MADE via three M20 cable glands accepting 0.34mm² to 1.5mm² conductors and short‑circuit protection of 4A gG is recommended.

What mechanical durability can be expected under normal use?

Mechanical life is specified as 1x10⁶ switching cycles with an actuation frequency up to 1,200/h.

How does the unit behave in fault conditions?

The switch contains no internal fault detection

any fault monitoring must be performed by the external safety‑related logic unit.
