Its thermoplastic housing provides not just impact resistance, but also reliable insulation to prevent you from receiving shocking surprises during operation. It's an essential piece of kit that you'll find in common industrial applications, including conveyor systems and compressors.
Features & Benefits
• High surge voltage resistance rating of 6kV to handle sudden voltage spikes without suffering damage
• Wide operating temperature range between -25°C and +60°C for use in demanding conditions
• Current rating of 6A makes it suitable for medium-current-consuming applications
Is this auxiliary contact finger-safe?
Yes, this unit has an IP20 rating, which means that it's touch-proof and protected from objects larger than 12mm in size, including wires and tools. This prevents accidental contact with live parts during operation for improved safety.
