Guardmaster 440N RFID 8-polig M12 Berührungsloser Sicherheitsschalter 24V dc aus Kunststoff, 2 PNP / 1, Einmalig codiert

440N-Z21U16H Non-Contact Interlock SwitchThe 440N-Z21U16H safety switch has 18mm plastic barrel housing, in red, and an 18mm actuator. It features a 6-inch pigtail, 8-pin Micro (M12) connector. This model has a unique coded actuator and the assured sensing distance is 15mm. It features LED indication for quick, easy diagnostics and door status.This contact-free switch can be used with Guardlink, a new safety linking technology from Allen Bradley Guardmaster. Guardlink simplifies and reduces the connection time of the safety system, whilst providing real-time diagnostic information over Ethernet IP. This makes it simple to identify the location of the device that has tripped the system, thus reducing downtime, and improving the machines overall efficiency. For more details, please go to the Guardlink brochure.What is RFID and how does it work?RFID stands for Radio Frequency Identification, which is a non-contact method of transferring digital data via radio frequency waves. Equipment with this type of wireless communication usually consist of an RFID tag, an RFID reader, and an antenna. The tag transmits data when triggered by an electromagnetic pulse from the reader. This technology is used widely in many industries, for example with tracking inventory goods, personnel tracking and identification, and restricted area access. Non-contact switches with this technology are highly tamper-proof as they cannot be manipulated, providing a higher level of security.
