SICK i14 Safety Interlock Switch, Power, Fibreglass Reinforced Thermoplastic, Electromagnetic

SICK i14 Series Safety Interlock Switch, 1000N Locking Force, IP65 - i14-M0303 Lock

This safety interlock switch is a power-to-release electromagnetic device designed to secure movable guards in industrial settings. It uses electro-mechanical sensing and provides monitored locking contacts for safeguarding access points. The unit operates on a nominal solenoid supply voltage range and is intended for integration with external safety logic for fault handling.

Features and Benefits:

• 1000N Locking Force provides strong guard retention
  20.4V to 26.4V DC Solenoid Supply enables controlled actuation
  3NC Safety Contacts allow positive-action monitoring
  IP65 Enclosure Rating permits use in dust- and water-exposed areas
  -20 to 60°C Temperature Range supports varied ambient conditions

Applications

• Suitable for securing machine access doors on production lines
  Ideal for integration with safety controllers for diagnostics
  Used with three-direction actuator approaches in Compact installations
  Can be used for guarding systems requiring electromagnetic locking
  Suitable for environments needing IEC 60529-rated enclosure protection

What electrical ratings must be observed for the switch contacts?

The contacts are rated for 3A at 240V AC and 2A at 24V DC and require a short-circuit protection device of 3A gG.

How is fault detection handled with this device?

The unit lacks internal fault detection so the connected safety logic must perform diagnostics and determine safe states.

Which connection method and conductor sizes are supported?

A single M20 cable gland is provided and conductors up to 1.5mm² can be used.

What is the expected mechanical and operational endurance?

Mechanical life is rated at 1x10⁶ switching cycles and actuation frequency is limited to ≤3,600 operations per hour.
