SERIES BNS33 & BNS33S Coded-Magnet Sensors Features & Benets 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 eld coded-magnets extends sensing range to 10mm. Units available with M8 quick-connect. (Please consult factory). Available stainless steel housing (BNS33S) ideal Description for the food industry. 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 eld array. Both switch and magnet assemblies are sealed to IP67 (submersible) standards (IP69K for BNS33S). Their tamper- resistant design prevents bypassing with a simple magnet or improperly coded magnetic eld. 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 eld aligns with the reed switch unit, the switches will close. When the guard is open, or the required magnetic-eld array is not properly aligned with the reed switch assembly, the sensor output will remain off. Required Safety Controller. 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. (Please see selection chart on Page 159.) USE WITH ANY OTHER SAFETY CONTROLLER MAY DAMAGE SENSOR AND/OR VOID WARRANTY. 134BNS33 AVAILABLE MODELS AND ACCESSORIES AVAILABLE STANDARD MODELS AVAILABLE ACCESSORIES (Please order BPS33 or BPS33-2326 magnet separately) Contact Maximum Part Number Description Part Number Description Conguration* Contact Rating Shim plate for mounting reed switch BN31/33 assembly on ferrous material BNS33-11z** 1 NO & 1 NC Multiple reed switch 100VAC/DC M8ST-2M Straight quick-connect with 2M cable assembly with 1-meter (400mA) M8ST-5M Straight quick-connect with 5M cable prewired pigtail BNS33-12z*** 1 NO & 2 NC M8ST-10M Straight quick-connect with 10M cable M8ST-15M Straight quick-connect with 15M cable BNS33-11zG** 1 NO & 1 NC Multiple reed switch assembly with 1-meter 24VDC M8ST-RA-2M Right-angle quick-connect with 2M cable prewired pigtail and (10mA) M8ST-RA-5M Right-angle quick-connect with 5M cable BNS33-12zG*** 1 NO & 2 NC built-in LED display Stainless-steel protective cover for BNS-SS-CVR BNS33-xxx Multiple reed switch 120VAC/DC assembly with 1-meter BNS33-12z-2187** 1 NO & 2 NC Stainless-steel protective cover for (250mA) BPS-SS-CVR prewired pigtail BPS33-xxx 100VAC/DC Multiple reed switch BNS33S-12z** 1 NO & 2 NC (250mA) assembly with 1-meter prewired pigtail and Coded Magnet stainless steel 24VDC Sensor BNS33S-12zG** 1 NO & 2 NC enclosure (10mA) Coded-magnet actuator BPS33 N/A N/A (5mm sensing distance) Coded-magnet actuator BPS33-2326 N/A N/A (10mm sensing distance) Stainless steel BPS33S N/A N/A coded-magnet actuator Multiple Reed Switch Assembly Safety Controller Coded-Magnet Sensor and 60VAC/DC BNS33-11z-ST** 1NO & 1NC (400mA) Safety Controller sold separately. 5 24VDC 1NO & 1NC BNS33-11zG-ST** (10mA) Multiple reed switch assembly with M8x1 quick-connect 60VAC/DC BNS33-12z-ST*** 1NO & 2NC (400mA) 24VDC 1NO & 2NC BNS33-12zG-ST*** (10mA) *Contact conguration in presence of BPS33 coded-magnet actuator. **These models feature isolated contacts. ***These models feature C-form contacts.
