SICK I15 Safety Switch, Power, Fibreglass Reinforced Thermoplastic, Power to Release

This safety switch is an electro-mechanical, power-to-release interlock designed for safeguarding access to guarded machinery. It provides door monitoring with positive-action contacts and is intended for direct wiring into safety logic units. The unit is supplied without an actuator and is housed in glass-fibre reinforced thermoplastic to withstand industrial environments while offering ingress protection suitable for washdown or dusty conditions.

• 2NC and 1NC contacts for secure door monitoring and lock supervision
• 4A rated operating current for AC-15/DC-13 switching duties
• Power-to-release locking with up to 2000N locking force for secure retention
• IP67 enclosure ensures protection against dust and temporary immersion
• Solenoid supply 20.4VDC to 26.4VDC supporting stable electromagnetic operation

• Suitable for machine guard interlocks with non-redundant safety logic
• Used with guarded doors requiring positive-action contact monitoring
• Ideal for industrial automation environments needing IP67 protection
• Can be used for securing access panels with power-to-release locks
• Suitable for systems operating up to +55°C ambient temperatures

A single M20 cable gland entry is provided and accepts conductors from 0.34mm² to 1.5mm².

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

The mechanical life is specified as 2x10⁶ switching cycles under standard conditions.

No actuator is supplied with delivery and must be ordered separately.

It is rated for operation and storage between -20°C and +55°C.
