Schmersal Magnetic Safety Switch Plastic Housing NO NC Cable IP67, 0.25A, 100V AC/DC, BNS33 Series

Schmersal BNS33 BNS 33-11Z-2M magnetic safety switch is an advanced non-contact safety interlock switch designed to maintain safety on industrial machinery access panels and assembly lines. It operates by detecting a coded magnetic actuator within range, which enables one electrical connection and breaks two others, ensuring high reliability and tamper resistance. Its black plastic rectangular housing is robust and suitable for concealed mounting, providing protection in industrial settings.

This safety switch supports normally open (NO) and normally closed (NC) contacts and can switch currents of up to 0.25A at voltages up to 100V AC/DC. The coded actuator principle eliminates the risk of bypassing the safety function with a standard magnet. The device offers an ingress protection rating of IP67, making it resistant to dust and temporary immersion in liquids for up to 30 minutes, ideal for harsh environments such as food and beverage processing or manufacturing.

The switch includes a two-meter PVC insulated cable for straightforward installation and connection and features an operating temperature range from -25°C to +70°C. Its compact dimensions, 88mm in length, 25mm in width, and 13mm in depth, allow flexible mounting options. The switch complies with internationally recognized safety and quality standards including IEC, EN, EAC, cULus, and BG, affirming its suitability for industrial automation and safety applications.

Typical applications include safety interlocking on machine access panels and in assembly-line production to protect operators and equipment. This unit is manufactured in Germany, assuring high build quality and durability. Note that this switch is not certified for explosive atmospheres; for such needs, the Schmersal BNS33 ATEX certified model is recommended.

The switch features a rectangular body with black thermoplastic housing. It supports safety contacts in NO and NC configuration. Designed for a switching current of 0.25A at up to 100V AC/DC. Equipped with coded magnetic actuator type to prevent bypass.

IP67 rated for protection against dust and temporary water immersion. Operating temperature range is -25°C to +70°C, suitable for demanding environments. Includes a 2-meter PVC-covered cable for easy connection. Switching distance is 18 mm ensuring reliable sensing performance.

Compact dimensions of 88mm length, 25mm width, and 13mm depth. Complies with IEC, EN, EAC, cULus, and BG standards for safety and quality. Explore more Schmersal safety switches and components on EnvMart for industrial and automation safety solutions.
