Man-machine safety specialist Schmersal has introduced the BNS-B20, a new door-handle that features an integrated coded magnetic safety sensor. It is designed for small to medium size guard doors and allows machine designers to specify a single assembly instead of a separate door.
Compared to standard safety switches with mechanical actuators, the BNS-B20 offers a number of significant advantages.
Easy to clean
No need for precise door alignment
No mechanical wear
Compact size
Safety rating to Cat 4 EN 954-1
Class PDF-M to IEC 60947-5-3
Can be used on left or right doors
