Schmersal EX-BNS 250 Series Non-Contact Safety Switch, 14mm Switching Distance, IP67 - EX-BNS 250-11Z-3GD
This non-contact safety switch is a magnetic sensor designed to monitor guarding and access points in environments with explosive atmospheres. Housed in fibreglass-reinforced thermoplastic, it offers non-intrusive actuation and a block-style body suited to demanding industrial installations. The device provides safety monitoring compatible with recognised safety category standards and connects via a fixed cable.
Features and Benefits:
• 14 mm switching distance enables non-contact operation
• Magnetic sensing provides wear-free actuation
• NO and NC safety contacts support fault-tolerant monitoring
• 24 V DC switching at 0.1 A permits low-voltage control circuits
• IP67 enclosure allows operation in dust and temporary immersion
• 1 m cable offers direct, sealed electrical connection
• Magnetic sensing provides wear-free actuation
• NO and NC safety contacts support fault-tolerant monitoring
• 24 V DC switching at 0.1 A permits low-voltage control circuits
• IP67 enclosure allows operation in dust and temporary immersion
• 1 m cable offers direct, sealed electrical connection
Applications
• Suitable for guarding on machinery in hazardous zones
• Used with safety control systems requiring EN ISO 13849-1 compliance
• Ideal for installations needing intrinsically safe components
• Can be used for perimeter monitoring in oil and gas facilities
• Used for access detection where sealed housings are required
• Used with safety control systems requiring EN ISO 13849-1 compliance
• Ideal for installations needing intrinsically safe components

What material resists corrosion and chemical exposure?
The housing is MADE from fibreglass-reinforced thermoplastic for improved chemical and mechanical resistance.
How is the switch connected into a control system?
It uses a 1 m attached cable terminated for direct wiring into control or safety circuits.
What certifications indicate suitability for explosive atmospheres?
The unit meets EN IEC 60079-0 requirements and applies to related hazardous-area standards.
Which protection level covers ingress from dust and water?
The enclosure rating is IP67, protecting against dust ingress and temporary immersion.
What contact arrangements are provided for safety logic?
The device includes both normally open and normally closed safety contacts for diverse monitoring schemes.
