The Euchner SGA2A-2121ASR11 is an advanced RFID-coded safety gate switch designed to safeguard access points in automated machinery. Featuring a non-contact actuator system with tamper-proof encoding, it delivers SIL 3/PLe safety integrity per ISO 13849-1. The compact stainless-steel housing (IP67/IP69K rated) withstands intense washdowns, oils, and vibrations in harsh environments like automotive plants or food processing lines.
Its dual-channel RFID technology detects gate positions within ±1 mm accuracy, while the integrated ASR-11 dynamic code system prevents manipulation. The switch monitors gate closure status via two independently evaluated OSSD outputs, enabling immediate machine halt upon unauthorized access. With tool-free mounting and M12 connectors, it simplifies retrofitting into existing safety circuits.
Precision specifications ensure failsafe operation:
- Safety Rating: SIL 3 (IEC 61508), PL e (ISO 13849-1 Cat. 4)
- Operating Principle: RFID non-contact with 2121-coded tongue actuator
- Switching Distance: 5-50 mm (adjustable via actuator positioning)
- Voltage Range: 24V DC (±15%) with reverse polarity protection
- Outputs: 2 PNP OSSD safety signals (3A @ 30V DC)
- Response Time: ≤15 ms for safety signal deactivation
- Ambient Temp.: -30°C to +85°C (operation), -40°C to +100°C (storage)
- Shock/Vibration: 100 m/s² shock (6 ms), 10g vibration (10-55 Hz)
- MTTFd: >100 years per EN ISO 13849-1
- Connections: 4-pin M12 plug (materials: PBT thermoplastic + nickel-plated brass)
Deployed for access control in high-risk zones:
- Robotic Workcells: Halts robots instantly when guards open during automated welding/assembly
- Packaging Machinery: Secures infeed chutes in pharmaceutical tablet press lines (GMP compliance)
- Plastic Injection Molding: Prevents mold access during 200°C+ cycles
- Automotive Conveyors: Monitors maintenance gates in paint shops with solvent exposure
- Metal Stamping Presses: Interlocks light curtains for multi-ton press brake protection
Ideal for applications requiring hygienic design (EHEDG-compatible) or frequent access cycles (>2 million operations).
Superior to mechanical switches through:
- Manipulation Resistance: ASR-11 dynamic coding changes RFID signals per cycle (ISO 14119 Type 4 compliance)
- Zero Physical Wear: Non-contact sensing eliminates friction failures common in lever-style switches
- Diagnostic Capabilities: Dual LEDs (green/red) indicate alignment, faults, or bypass attempts from 10m distance
- Effortless Installation: Symmetrical design enables horizontal/vertical mounting; no wiring tools needed
- CrossTalk Immunity: ≤5mm tolerance between adjacent switches prevents signal interference
Reduces maintenance costs by 60% vs. mechanical alternatives while achieving ≤0.01% false-trip rates.
Advanced safety integration includes:
- Dynamic Code Verification: Actuator and base exchange encrypted RFID signals to confirm position identity
- Floating Voltage Detection: Auto-identifies common 24V/48V DC safety controller inputs
- Redundancy Monitoring: Two independent processor channels cross-check gate status at 5ms intervals
- Self-Testing Logic: Continuous diagnostics for coil faults, wiring shorts, or voltage drops
- Muting Function: PLC-controlled permissives (via auxiliary cables) allow timed access during automated sequences
Seamlessly interfaces with safety relays (Pilz, Sick) and PLCs via DeviceNet™ or PROFIsafe protocols.
