The BK400P is a Smart Series Pull Trip type pull wire switch, manufactured from marine-grade LM6 powder coated aluminium. It stops a conveyor immediately in the event of a pull activation or wire break, using a dual trip shaft design where each shaft operates completely independently from the other.
Internal components are made from stainless steel, nylon, copper and brass for strong corrosion resistance. The switch is SIL2 Capable (IEC 61508 certified) and complies with AS/NZS 4024.3610:2015 and BS EN ISO 13850:2008.
The BK400P also integrates into the broader Smart Series conveyor safety ecosystem, pairing with monitoring nodes, pre-start sirens, and Smart Series Essentials like pigtails and cable wedge clamps for a complete trip detection and indication solution.
