Mechanical wear and misalignment problems associated with rugged environments, are also eliminated.
The technologically advanced BNS33 AS also cuts wiring time in half by eliminating the need for an I/O block and connecting directly to the AS-i yellow cable through an M12X1 connector.
Its magnetic signal also operates through stainless steel and thermoplastics, allowing greater flexibility for concealed mounting on work surfaces and in storage areas.
Configuration and commissioning is easy using Asimon "drag and drop" software and a hand-held programming tool - simply choose the safety device, connect it to the yellow AS-i cable, set the safety function in the safety monitor and that's it.
Schmersal estimates that companies can save between 20% and 30% on AS-i Safety at Work installations by eliminating I/O blocks and the extra wiring needed to install them.
Like other Schmersal AS components the BNS33 AS is suitable for safety applications up to Control Category 4 to EN 954-1 and has been tested and approved by TUV safety standards authorities.
It also corresponds to Euro Norm EN 50295.
