Coded-Magnet Sensors  
Features & Benefits  
SERIES BNS250  
• 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.  
Description  
AVAILABLE STANDARD MODELS  
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.  
(Please order BPS250 magnet separately)

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.

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.”

*Important Note: Series BNS Coded-magnet sensors are for use  
in safety applications only when used with a  
SCHMERSAL Series AES safety controller.  
(Please see selection chart on Page 130.)  
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.  
USE WITH ANY OTHER SAFETY CONTROLLER MAY  
DAMAGE SENSOR AND/OR VOID WARRANTY.
