Schmersal EX-AZ 16 Series Safety Interlock Switch, IP67, Fibreglass Reinforced Thermoplastic Housing - EX-AZ 16-12ZVK-3D

This safety interlock switch provides approved protection and control for hazardous environments, combining environmental sealing with certified hazardous-area suitability. It is intended to monitor access or guard positions where electrical isolation and circuit interruption are required, operating across a defined temperature range and conforming to established control-circuit standards.

Features and Benefits:

• IP67 enclosure prevents ingress in wet or dusty conditions
• Fibreglass-reinforced thermoplastic housing resists mechanical and chemical wear
• Two normally-closed Plus one auxiliary contact simplifies safety-circuit design
• Compatible with 24 V AC and 24 V DC control supplies for versatile use
• Operates reliably between -20°C and +70°C for varied site conditions

Applications

• Suitable for safeguarding enclosures in classified hazardous areas
• Ideal for integration into machinery safety-interlock circuits
• Used with control panels that require Compact actuator devices
• Can be used for perimeter access monitoring in industrial plants

What environmental protection does it provide?

It offers IP67-rated sealing to protect internal components from dust ingress and temporary immersion.

How are safety and auxiliary contacts configured?

The unit provides two normally-closed safety contacts Plus one auxiliary contact to support both safety-loop interruption and signalling.

What materials constitute the external casing?

The outer housing is MADE from fibreglass-reinforced thermoplastic to provide structural integrity and resistance to degradation.

Which temperatures can it withstand during operation?

It is specified to operate across a temperature span from -20°C up to +70°C.

What standards and certifications are relevant for hazardous installation?

It carries IECEx hazardous-area certification and meets EN/IEC 60947-5-1 control-circuit standards.
