Schmersal BNS33 Series Magnetic Safety Switch, Plastic Housing, 24V DC, NC, 2 NO, Cable BNS 33-12ZG-2187-2M

Schmersal BNS 33-12ZG-2187-2M magnetic safety switch is an advanced safety device tailored for securing hazardous machine areas and protecting operators from harm. This non-contact switch employs a coded magnetic actuator detection mechanism to prevent tampering and bypass attempts common with standard magnets. Its robust rectangular plastic housing features a black thermoplastic enclosure that is self-extinguishing, ensuring safety even in fire scenarios. The device operates on 24V DC and offers NC and 2 NO safety contacts, providing versatility in wiring safety circuits.

The switch's IP67 rating certifies complete protection against dust and temporary immersion in water, making it suitable for challenging environments including industrial and food processing applications. With a switching capacity of 0.25A and an operating temperature range from -25°C to +70°C, this switch maintains reliable performance across diverse industrial conditions. The one-metre long PVC-covered cable allows easy connection and installation.

Dimensions of 88mm length, 50mm width, and 13mm depth allow compact integration on control panels or machine guards. It meets stringent standards including BG, cULus, EAC, IEC, and EN to ensure it fits safety regulatory requirements in multiple markets.

The switch is well-suited for applications such as machine access panels, assembly lines, and food and beverage processing plants where operator safety is critical. With an operating frequency capability of up to 5 Hz, it can rapidly detect the position of safety guards. LED indicators conveniently signal guard door status to operators and maintenance staff.

This product does not include an actuator; a matching coded actuator (part number 198-7863) is sold separately to complete the safety circuit. The magnetic sensor principle ensures no physical contact wear, prolonging operational lifespan and reducing maintenance intervals.

The switch is compatible with demanding industrial, manufacturing, and automation safety systems. The thermoplastic plastic housing material offers chemical resilience and mechanical durability. The coded actuator prevents bypassing by standard magnets, ensuring enhanced security.

Overall, the Schmersal BNS 33-12ZG-2187-2M is a reliable, high-performance magnetic safety switch engineered for modern industrial safety requirements. Explore the full range of Schmersal industrial Safety Switches and components on EnvMart for comprehensive machine safeguarding solutions.
