Schmersal BNS 303 Series Safety Switch, 15mm Switching Distance, IP67 - BNS 303-11ZG 3,0M

This safety switch is a magnetically actuated interlock designed for safeguarding access points in industrial control systems. It operates as a non-intrusive sensor that monitors guard positions and communicates state via wired connection, suited to environments where a compact, sealed device is required.

Features and Benefits:

• IP67 rating provides dust-tight, temporary immersion protection
• Magnetic sensing enables contactless position detection
• 24 V DC operation supports low-voltage control architectures
• 0.01 A switching current allows compatibility with sensitive circuits
• Two auxiliary contacts give additional signalling options
• NO and NC safety contacts permit flexible safety logic

Applications

• Suitable for guarding machine access panels requiring sealed devices
• Ideal for integration with control systems using low-voltage signalling
• Used for monitoring movable guards where non-contact sensing is preferred
• Can be used for needing auxiliary feedback circuits
• Used with installations that require a cable-connected interlock

What connection method does it use for wiring?

It connects via a factory-fitted 3 m cable providing a fixed electrical interface.

What housing material is used to withstand industrial conditions?

The enclosure is MADE from fibreglass-reinforced thermoplastic for mechanical resilience.

What safety performance standard is referenced for its category?

It is rated to EN ISO 13849-1 for its safety-category designation.

What approvals cover electromagnetic and safety switching behaviour?

It holds cULus and EN IEC 60947-5-3 approvals for relevant electrical safety requirements.

Does it include an actuator with the unit?

No actuator is supplied with the switch and a separate magnet actuator is required.
