SBG257 IFM Return Valve Flowmeter New Original Plc Programming Controller Module

2. Key Selling Points

1. Designed for Safety Applications: The SBG257 is a safety interlock switch specifically designed to monitor the safety status of protective doors, guards, and hinged panels. It complies with international safety standards such as ISO 13849-1 Cat. 3, PL d and IEC 62061 SIL 2, ensuring personnel and equipment safety.
2. Positive Opening Action (Forced Disconnection): Features a positive opening mechanism where the normally closed (NC) contacts are mechanically forced apart. This ensures reliable circuit disconnection even in the event of contact welding or other failures, a critical feature for achieving functional safety.
3. Non-Contact Magnetic Sensing: Utilizes magnetic principles for non-contact detection, resulting in no mechanical wear, extremely long service life, maintenance-free operation, and immunity to performance degradation from dust, oil, or other contaminants.
4. High Protection Rating: Boasts an ultra-high protection rating of IP67/IP68/IP69K, providing dust-tight sealing, long-term underwater operation, and resistance to high-pressure, high-temperature water/steam cleaning. This makes it ideal for hygienic applications in food, beverage, and pharmaceutical industries requiring frequent washdowns.
5. Robust All-Metal Housing: Constructed with a stainless steel (1.4404 / V4A) housing, offering exceptional corrosion resistance, mechanical strength, and wear resistance, suitable for harsh industrial environments.
