SICK RE21 Series Magnetic Non-Contact Safety Switch, 30V dc, Plastic Housing, NC, M8 - RE21-SAC

The actuators are only coded in the sense that they have an identical magnetic combination making them type specific not individual example specific. SICK RE1 ; RE2 Series of Non-Contact Safety Switches. RE1 ; RE2 magnetic safety switches are equipped with NC/NO contacts or equivalent N/O contacts which are treated directly with coded magnetic actuators. These types of safety system switches are particularly useful in areas where there may be a high level of contamination (these units are simple to clean and keep high hygiene standards). Features and Benefits. Response range from 7-9 mm. Magnetic sensor principle. Built-in LED response indicator. Performance level up to PL e / Cat. 4 (EN ISO 13849). Glass-fibre reinforced PPS rectangular housing. High tolerances for door misalignment. 2-3 contacts (see specifications). Enclosure rating IP67 (IEC 60529). Typical applications. The RE1 ;2 series are compatible anywhere where a high standard of hygiene is necessary for operations. Typically, you'll find these types of safety switches where precise guidance of a safety door isn't always possible. Monitoring of safety doors ; removable guards. Applications requiring a high standard of hygiene.
