1. Product Overview:

️· Type: Non-contact safety switch (part of the STR1 series).
️· Function: Used for safety-related applications to detect the position of a moving guard or safety component. It's designed to shut down machinery if a safety condition is violated.
️· Coding: Uses a high-level coding system for the actuator (the part that moves). This helps prevent unauthorized manipulation or accidental triggering.

2. Key Features & Specifications:

️· Sensing Principle: Non-contact (uses a magnetic field or similar to detect the actuator).
️· Safety Level: Meets stringent safety standards (SIL2, Category 4, etc.).
️· Housing: Robust VISTAL® housing, IP67/IPX9K rated (dust-tight and water-resistant).
️· Supply Voltage: 24V DC
️· Output: Semiconductor outputs (OSSD - Output Signal Switching Device)
️· Response Time: Approximately 40ms (system response time will increase in cascade).
️· Vibration/Shock Resistance: Designed to withstand industrial environments.
️· EMC: Meets relevant EMC standards.
️· Dimensions: 40mm x 18mm x 26mm
️· Actuator Coding: Uses high coding level for increased security and prevention of tampering.

3. Technical Highlights:

️· Safety Categories: Meets Category 4 (EN ISO 14119) safety requirements.
️· Performance Level (PL): d (EN ISO 13849-1)
️· Safety Integrity Level (SIL): 2 (IEC 61508)
️· Diagnostic Coverage: High diagnostic coverage for detecting faults.

4. Installation and Wiring:

️· Connection: Uses a cable with standard wiring (Brown = 24V DC, White = OSSD 1, Blue = 0V DC, Black = OSSD 2, Grey = Aux Output).
️· Actuator Range: The datasheet indicates that a 9mm or 14mm switching distance must be maintained.
️· Cascading: Multiple switches can be connected in series (cascaded) to protect larger areas. It's important to note that the response time will increase with each switch added.

5. Accessories:

️· SICK recommends the use of M3 x 12 safety screws.

6. Applications:

️· Safety guarding on machines
️· Door and gate monitoring
️· Robotic cell safety
️· Other safety-related applications where reliable detection of a guard’s position is critical.

7. Important Notes:

️· Safety Documentation: Always refer to the complete operating instructions for detailed safety information.
️· Risk Assessment: A thorough risk assessment must be performed before using this product to ensure it is suitable for the application.
️· Qualified Personnel: Installation and maintenance should only be performed by qualified personnel.

In essence, this datasheet provides the crucial technical details needed by engineers, technicians, and safety professionals to select, install, and maintain the SICK STR1-SAMU10P5 safety switch in safety-critical applications.
