⚙️ Core Technical Innovations

1. Safety-First Auxiliary Configuration

• Dedicated N.C. (Normally Closed) Contact: Engineered for safety-critical circuits, this contact opens when the coil energizes, providing immediate shutdown capability in emergency scenarios.

• 0 N.O. Design: Eliminates accidental activation risks by excluding normally open auxiliary circuits, making it ideal for ISO 13849 Category 3/4 safety systems.

2. Dual-Voltage Coil Flexibility

• TC-473 Coil System: Supports both 110V 50Hz and 120V 60Hz operation (±15% tolerance) with a single spare part, reducing inventory costs by 40%.

• Line-Side Termination: Simplifies wiring in safety control panels and enables direct integration with e-stop buttons or safety relays.

3. Robust Construction

• Vibration-Resistant Screw Terminals: Maintains connection integrity under 10G mechanical stress (IEC 60068-2-6).

• Silver-Tin Oxide Main Contacts: Withstand 750,000 operations at 23A AC-3 load with <2mV voltage drop.
