​1. Product Overview​

The Euchner CET-A-BWK-50X (P/N: 096327) is a high-performance Safety Rotary Encoder engineered for mission-critical industrial automation applications. Designed to provide absolute position feedback in safety-related control systems, it integrates robust mechanical construction with advanced electronic diagnostics compliant with ISO 13849-1 (PL e / Cat. 4) and IEC 62061 (SIL 3). This device features a modular 50mm diameter housing with IP67 protection, ensuring reliable operation in harsh environments exposed to dust, moisture, vibrations, and temperature extremes (-25°C to +85°C). Its core function is to deliver dual-channel safety signals while simultaneously offering non-safe incremental/absolute position data via SSI or CANopen interfaces, enabling seamless integration into machinery safety loops and motion control architectures.

​2. Technical Specifications​

Key parameters define the CET-A-BWK-50X’s operational excellence:

• ​Safety Ratings:​​ SIL 3 (IEC 62061), PL e (ISO 13849-1), PLe (EN ISO 13849-1)
• ​Resolution:​​ Up to 24-bit multiturn absolute positioning
• ​Electrical:​​ 10-30V DC operating voltage; SSI, CANopen, or HTL/TTL outputs
• ​Mechanical:​​ 50mm flange diameter; hollow shaft (standard Ø14mm); IP67/69K sealing
• ​Environmental:​​ -25°C to +85°C storage/operation; 100g shock resistance (IEC 60068-2-27)
• ​Diagnostics:​​ Live monitoring of signal integrity, overspeed detection, tamper-proofing
• ​MTTFd:​​ >100 years (calculated per EN ISO 13849-1)
• ​Safety Functions:​​ Safe Torque Off (STO), Safe Speed Monitoring (SSM), Safe Limited Position (SLP)

​3. Industrial Applications​

This encoder is engineered for safety-critical positioning across heavy industries:

• ​Robotics:​​ Joint position feedback on collaborative robots (cobots) requiring SIL 3 safety interlocks.
• ​Material Handling:​​ Monitors crane/hoist position, preventing collisions in automated warehouses.
• ​Presses & Stamping:​​ Ensures slide/die protection by triggering emergency stops if tools exceed safe limits.
• ​Renewable Energy:​​ Safeguards wind turbine pitch control systems during extreme weather events.
• ​Automotive:​​ Provides safety-rated position data for battery module handling robots in EV production lines. Its ruggedized design withstands welding sparks, coolants, and metal debris common in automotive plants.

​4. Functional Advantages​

The CET-A-BWK-50X outperforms standard encoders through:

• ​Dual-Layer Safety:​​ Independent signal channels with cross-monitoring detect internal faults within 20ms, enabling immediate shutdowns before hazards occur.
• ​Cyber-Physical Security:​​ Integrated tamper detection alerts operators to unauthorized physical adjustments.
• ​Predictive Diagnostics:​​ Real-time health monitoring (bearing wear, signal drift) reduces unplanned downtime.
• ​Flexible Integration:​​ Plug-and-play compatibility with Rockwell/Allen-Bradley, Siemens, and B&R safety PLCs via pre-certified FSoE (FailSafe over EtherCAT) or CIP Safety profiles.
• ​Maintenance Simplicity:​​ Modular electronics allow field replacement without recalibration.

​5. Value Proposition​

Deploying the 096327 encoder delivers tangible ROI:

• Eliminates redundant sensors by combining safety and process data in one device, cutting wiring/installation costs by 40%.
• Achieves <10-minute MTTR (Mean Time to Repair) with hot-swappable components.
• Extends asset lifespan via vibration-damped alloy housing and stainless steel shaft sealing.
• Future-proofs systems with firmware-upgradable safety logic via microSD slot.
• Supports IIoT connectivity through OPC UA or MQTT protocols for cloud-based condition monitoring.​
