SICK STR1 Series RFID Non-Contact Safety Switch, Vistal Housing, 24V DC, 2 NO Contacts, M12 Connector STR1

SICK STR1 Series RFID Non-Contact Safety Switch, model STR1, features a 24V DC power supply with 2 Normally Open (NO) safety contacts and an M12 connector for industrial safety applications. The device is encased in a durable Vistal housing designed to withstand challenging environments, offering IP67 ingress protection.

Designed for non-contact safety monitoring, this switch utilizes RFID sensor technology to provide a secure and reliable safety interlock system for machinery access points. It supports SIL3 safety integrity level to meet high-risk application standards and provides Category 4 performance level PL e for functional safety, ensuring maximum operator protection.

The switch offers a 28mm switching distance assuring safe separation between the actuator and sensing unit. It features a maximum switching current of 100mA suitable for low power outputs, and is equipped with an auxiliary non-safe contact enhancing its control capabilities.

For integration convenience, the switch uses a 5-pin M12 connector with a 0.2m lead, supporting cable lengths up to 200m. Visual status and diagnostic information are indicated via LEDs on the housing, simplifying fault identification during maintenance.

Industrial use cases include machine-guard interlocking, non-contact safety monitoring on production lines, and integration with safety controllers using Flexi Loop in series connections. The device is particularly suited for guarding doors requiring high safety categories.
