Description
The Series BNS250 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.
Both switch and magnet assemblies are sealed to IP67 (submersible) standards. Their tamper-resistant design prevents bypassing with a simple magnet or improperly coded magnetic field. In addition, the BNS module features a 1- meter long prewired pigtail.

FEATUREs & Benefits
• 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 installation and provide visual indication of switch status.
• Shock and vibration tolerant … designed to withstand mechanical abuse.
• Satisfy CE & fail-to-safe requirements … when used with Series AES safety controllers.

Typical Applications
  The sealed, compact BNS250 is ideal for use on movable machine guards in hostile environments. Typical applications include food processing equipment, chemical processing equipment, woodworking machinery, packaging machinery, and articulating robot arm rest position sensing.
