SICK RE21 Safety Switch, 1NO/1NC Actuator Included, Vistal, Magnet Lock

RE2 magnetic safety switches are equipped with either complementary NC/NO contacts or equivalent N/O contacts which are addressed directly with coded magnetic actuators. Magnetic safety switches are used in areas where a high level of contamination occurs.

They are simple to clean, thereby enabling high standards of hygiene. Their principle of operation enables greater tolerances, making them ideal for applications where precise guidance of the protective device is difficult.

Response range of up to 9 mm
2 or 3 contacts
Up to performance level PL e / Cat. 4 (EN ISO 13849)
Sensors with plug connector or connected cable
LED status indicator (RE27)
Flexi Loop-compatible M12 plug connector (depending on variant)

Long service life due to durable and low-maintenance design
Just one safety switch in conjunction with a suitable safety module makes it possible to solve applications up to PL e and Cat. 4 (EN ISO 13849)
High level of machine availability due to high tolerances for door misalignment
The devices are easy to clean, making them suitable for contaminated areas or environments with strict hygiene standards
Fast diagnostics via LED status indicator (RE27)
Flexi Loop now enables a safe series connection with enhanced diagnostics capabilities and minimal wiring effort.

Fields of applications
Monitoring of safety doors and removable guards
Applications requiring a high standard of hygiene
Applications where precise guidance of the safety door is not possible
