Schmersal BNS303 Series Magnetic Safety Switch รหัส BNS 303-11ZG-ST

Protect your industrial machinery with this non-contact safety switch from Schmersal. It functions by sensing the position of a magnetic actuator to make one electrical connection and break a second one. The device can be mounted in a concealed position, and the robust thermoplastic enclosure ensures longevity and resistance to chemicals. The switch conforms to the EN60947-5-3 standard if the entire system is composed of a BNS 303-series safety sensor, a magnet (BPS 303 series) and a safety-monitoring module (AES series). The actuating magnet for the switch (617-5330) can be bought separately.

• Coded actuator type to prevent bypassing with a simple magnet
• Insensitive to transverse misalignment, making mounting simpler
• IP67 (ingress protection) rating means it's dust-tight and water-resistant

• Security systems
• Machine access panels
• Assembly lines
• Food and drink production

A non-contact safety switch operates without the use of conductive contacts to complete or break a circuit. Instead, it uses a magnet, transponder or inductor to detect when the power to a machine needs to be cut or can be restored.
