SERIES BNS-B20New!Coded-Magnet Sensor withSafety Door HandleFeatures & Benefits• Tamper-resistant … cannot be bypassed with simplemagnets• Sealed for submersibility … assures long-term reliabilityin the most hostile environments.• Dual-function latch & sensor … integral magnetic holdinglatch (with force of 100N).• Application flexibility … 3-contact design compatible with35mm, 40mm, and 45mm aluminum profiles• Long-life … no mechanical wear due to non-contactdesign.• Satisfies EN 954 Safety Control Category 4 … whenused with compatible SCHMERSAL Series AES safetycontroller.• Easy-to-install … optional M12 x 1 quick disconnect &LED status indicator in NC circuit• Application diversity … suitable for hinged & slidingguards, available for left- or right-hand doors/guards.• Integral LED … displays switch status (non-LED modelsalso available).DescriptionThe Series BNS-B20 is designed for use as a combinationdoor handle and safety interlock switch for use on light tomedium weight hinged and sliding machine guards. Eachunit consists of a door handle assembly equipped with twomultiple reed switch arrays and coded magnet actuators. Inaddition, the unit features two latching magnets that attractpole pieces in the sensor unit—providing a holding force ofapproximately 100 Newtons.The reed switches will only close in the presence of theirmatched magnetic field array … thus enabling machineoperation. Both switch and magnet assemblies are sealedto IP67 standards. Their tamper-resistant design preventsbypassing with simple magnets. The unit also features anLED display of switch status and an optional M12x1 quickconnectfor ease of wiring and installation.OperationThe unit consists of two components … the door handle unitand the sensor unit. The sensor unit is typically mounted tothe stationary portion of the guard structure, with the codedmagnet/handleassembly mounted to the movable element ofthe machine guard.When the guard is closed, the matched magnetic fields alignwith the reed switch arrays, closing the switches and enablingmachine operation. When the guard is open, or the magneticfields are not properly aligned with their reed switch arrays,the sensor output will remain “off.”Typical ApplicationsThe sealed low-profile, ergonomic door handle system is idealfor use on movable machine guards in hostile environments.The absence of protruding elements eliminate/reduce risk ofinjury and unintentional opening of the guard. Typical applicationsinclude food processing equipment, chemical processingequipment, woodworking machinery, packaging machinery,and printing equipment.AVAILABLE STANDARD MODELS & ACCESSORIES*(Please order sensor, actuator-door handle unit andoptional connector separately)Part Number Description TerminationBNS-B20-12ZG-LBNS-B20-12ZG-RBNS-B20-12ZG-HBNS-B20-12ZG-ST-LBNS-B20-12ZG-ST-RSensor unit for left-handhinged doorSensor unit for right-handhinged doorSensor unit for both rightandleft-hand hinged doorSensor unit for left-handhinged doorSensor unit for right-handhinged doorBNS-B20-B-01 Actuator-door handle unit N/AM12-8P-5M5m cable with M12x1,N/A8-pin connectorNote: Sensor unit is also available for ASI Safety-at-Work bussystems.
