CsS-Y-8P - 8-Pin Mechanical Interlock Switch IP67 Nylon Industrial Connector

1. Product Overview

​
The Schmersal CsS-Y-8P is a high-security electromechanical safety switch designed for critical access control to hazardous machinery areas. Featuring a ​robust zinc die-cast housing (IP67 rated)​, this device utilizes ​RFID-coded actuator technology​ to prevent tampering and defeat attempts. The "Y" designation indicates its bright yellow actuator head for high visibility, while "8P" specifies the 8mm switching distance capability. This switch operates through proximity-based communication between the fixed switch body and a separate RFID-coded actuator mounted on movable guards. When the guard closes, the actuator aligns within 8mm, enabling the RFID signal to authenticate and maintain safety contacts in the safe position. Opening the guard breaks this communication, triggering immediate machine shutdown. Designed for SIL 3/PL e applications, it provides reliable guard monitoring in demanding industrial environments including manufacturing plants and automated facilities.

​2. Key Technical Parameters

​
Operating at ​24V DC ±10%​, the CsS-Y-8P achieves ​ISO 13849-1 PL e (Category 4)​​ and ​IEC 62061 SIL 3​ safety ratings. It features ​dual-channel force-guided contacts​ (1 NC + 1 NO) rated at ​6A/250V AC. The RFID system operates at ​125kHz frequency​ with ​encrypted data transmission​ to prevent code copying. Environmental specifications include ​​-25°C to +70°C operating temperature, ​IP67 protection​ against dust and water immersion, and ​30g shock resistance. The 8mm switching distance provides significant installation tolerance (±5mm lateral alignment). Mechanical endurance exceeds ​1 million operations, while the integrated LED indicators display power status, guard position, and diagnostic conditions. Connection is facilitated through ​M12 5-pin connectors​ with gold-plated contacts for reliable signal transmission.

​3. Primary Applications and Use Cases​
This safety switch is essential for securing access points where tamper resistance is critical:

• ​Robotic workcells: Preventing unauthorized access during automated operations
• ​Press brake machinery: Monitoring safety light curtain bypass doors
• ​Plastic injection molding: Securing mold area access gates
• ​Automated assembly lines: Guarding maintenance hatches on conveyor systems
• ​CNC machining centers: Controlling access to tool change areas
• ​Material handling systems: Securing robotic palletizing cell entry points
• ​Pharmaceutical cleanrooms: Monitoring isolator doors in sterile environments
  Its RFID technology provides superior security in applications where conventional magnetic switches could be defeated with external magnets. The IP67 rating makes it suitable for washdown areas in food processing plants and environments with metal dust/chip exposure.

​4. Product Advantages and Functional Benefits​

• ​Tamper-Resistant Security: Encrypted RFID coding prevents defeat with external magnets
• ​High Misalignment Tolerance: 8mm switching distance accommodates installation variances
• ​Diagnostic Capabilities: Dual-channel monitoring detects contact welding faults
• ​Visual Status Indicators: Multicolor LEDs provide instant operational feedback
• ​Robust Construction: Zinc housing withstands impacts up to 50J (IK10)
• ​Simplified Wiring: M12 connectors enable plug-and-play installation
• ​Global Compliance: Meets EN ISO 14119 Type 4 requirements
• ​Maintenance Reduction: Hermetically sealed contacts prevent corrosion failures
• ​Safety Integrity: SIL 3/PL e certification enables use in Category 4 circuits
• ​Extended Service Life: >1 million mechanical operations reduce replacement frequency

​5. Core Functionality and Safety Operation​
The CsS-Y-8P operates through secure RFID communication between the actuator and switch body. When the guard closes, the actuator comes within 8mm, enabling the RFID chip to transmit its encrypted code. The switch's internal reader validates this code and maintains the ​Normally Closed (NC) safety contact​ in the closed position. Simultaneously, the ​Normally Open (NO) diagnostic contact​ changes state to confirm proper operation. Opening the guard breaks this communication, causing the NC contact to positively open within 15ms, initiating machine stop. Crucially, the ​force-guided relay design​ ensures mechanical linkage between contacts - if the NC contact welds closed, the NO contact cannot change state, creating a detectable fault. Safety controllers monitor both contact states; any discrepancy triggers immediate shutdown and prevents restart until resolution. Manual reset requires physical guard closure and deliberate reset command after fault clearance. The RFID system prevents unauthorized access by requiring exact code matching, while the 8mm operating distance accommodates thermal expansion and vibration-induced movement.
