SERIES BNS33 & BNS33S Coded-Magnet Sensors Features & Benefits Description The Series BNS33 coded-magnet sensors are designed for use as a safety interlock switch on movable machine guards/articulating robot arms. Each sensor set consists of a multiple reed switch unit and a coded-magnet actuator. The reed switches, wired in series, will only close in the presence of their matched magnetic field array. • Compact size … ideal for limited space applications. • Sealed for submersibility … assures long-term reliability in the most hostile environments. • Tamper-resistant … cannot be bypassed with simple magnets. • Rugged, corrosion-resistant housing … tolerates most industrial environments. • Integral LED status indicators … facilitate easy installations and provide visual indication of switch status. • Shock and vibration tolerant … designed to withstand mechanical abuse. • Satisfy EN954, Category 1, 3, or 4 … when used with appropriate Series AES safety controllers. • Optional high-strength field coded-magnets … extends sensing range to 10mm. • Units available with M8 quick-connect. (Please consult factory). • Available stainless steel housing (BNS33S) … ideal for the food industry. Both switch and magnet assemblies are sealed to IP67 (submersible) standards (IP69K for BNS33S). Their tamperresistant design prevents bypassing with a simple magnet or improperly coded magnetic field. In addition, the BNS module features an optional built-in LED display of switch status, and a 1-meter long prewired pigtail to assure sealing integrity. Operation The reed switch assembly is typically mounted to a stationary portion of a guard structure, with the coded-magnet assembly mounted to the movable element of the machine guard. When the guard is closed, and the matched magnetic field aligns with the reed switch unit, the switches will close. When the guard is open, or the required magnetic-field array is not properly aligned with the reed switch assembly, the sensor output will remain “off.” Typical Applications The sealed, compact BNS33 is ideal for use on movable machine guards in hostile environments or where space is limited. Typical applications include food processing equipment, chemical processing equipment, woodworking machinery, packaging machinery, and articulating robot arm rest position sensing. *Important Note: Series BNS coded-magnet sensors are for use in safety applications only when used with a SCHMERSAL Series AES safety controller.
