Allen-Bradley 100-C12D01 The Space- Safety Solution for Packaging Equipment with a 0 N.O./1 N.C. Auxiliary Configuration

Allen-Bradley 100-C12D01 Contactor: The Precision Safety Sentinel for Compact Control Systems

In industrial automation environments where space constraints and functional safety converge, the Allen-Bradley 100-C12D01 emerges as a purpose-engineered solution within Rockwell Automation's Bulletin 100-C series. Featuring a specialized 0 N.O./1 N.C. auxiliary configuration and optimized 12A power rating, this UL-certified contactor delivers failsafe performance for compact machinery, pilot control circuits, and safety interlocks where conventional contactors are over-specified. Designed for OEMs requiring ISO 13849 compliance in packaging equipment, laboratory instruments, and small robotics, the 100-C12D01 combines space efficiency with uncompromising safety integrity.

Core Safety Engineering Innovations

1. Micro-Scale Safety Architecture

• Dedicated N.C. (Normally Closed) Contact: Opens within 25ms of coil energization, providing hardwired de-energization proof for Category 2 PL c safety circuits

• 0 N.O. Design: Eliminates accidental circuit closure risks in intrinsically safe systems

• Position 2 Terminal Marking: Enables drop-in replacement of legacy safety devices without panel redesign

2. Space-Optimized Construction

• Compact Footprint: 45% smaller than standard 23A contactors (45×80×75mm)

• Vibration-Resistant Terminals: Maintain connection integrity at 12G acceleration (tested per IEC 60068-2-6)

3. Energy-Efficient Operation

• 110V 50Hz TA-473 Coil: Consumes only 1.2W during holding state

• Surge-Protected Circuitry: Integrated varistor protects against 2kV transients
