Schmersal BNS33 Series Magnetic Safety Switch (Model BNS 33-02Z-2187-3M) is a high-quality safety switch designed for industrial machine guarding to prevent personnel injury. Featuring a coded magnetic actuator principle, this safety switch establishes two normally closed (NC) electrical contacts when the actuator is in proximity, preventing unauthorized opening with standard magnets.
The switch housing is constructed from durable black plastic and rated IP67, making it resistant to dust and capable of short-term submersion in water. It operates reliably within temperatures from -25°C to +70°C.
Electrical specifications include a maximum switching current of 0.25A and voltage up to 100V AC/DC, suitable for controlling safety circuits.
The switch has a rectangular form factor measuring 88mm in length, 50mm in width, and 13mm in depth. It includes a 3 metre PVC-covered cable facilitating connection without additional accessories. The switch is insensitive to transverse misalignment, streamlining installation procedures.
Certifications to IEC, BG, cULus, EAC, and EN standards ensure compliance with industry regulations across multiple markets.
Common applications include machine access panels for safety interlocking, assembly line automation safety, and food processing environments where hygiene standards require non-contact switches.
This magnetic safety switch employs coded actuator technology to provide secure and tamper-proof operation. Its IP67 rating ensures durability even in harsh and wet industrial environments. The plastic housing is robust and designed for concealed mounting options.
With operating temperatures from -25°C to +70°C, it is suitable for varied industrial settings. The device simplifies wiring with a 3-metre PVC cable included. Its switching distance parameters allow precise detection and safety control.
Compliant with multiple international safety and electrical standards. Offers reliable performance with low current and voltage limits ideal for safety circuits. Insensitivity to transverse misalignment decreases installation complexity.
