Two-hand control devices are safety-critical components designed to ensure operator protection in industrial machinery by requiring simultaneous activation with both hands. These devices, also known as two-hand safety controls or anti-tie-down controls, are typically configured as electromechanical or electronic units with dual-channel monitoring. They feature redundant contact blocks, often with forced-guided contacts (mirror contacts) per EN 60947-5-1, and are rated for operational voltages up to 400V AC with current ratings from 2A to 10A. The devices include pushbuttons with mechanical interlocks to prevent bypassing, and some models offer IP65 protection for harsh environments. They are essential for compliance with ISO 13851 and EN 574 standards, ensuring that operators keep both hands away from hazardous zones during machine cycles.
Two-hand control devices are widely deployed in sectors such as metalworking, woodworking, plastics processing, and automotive assembly. They are installed in punch presses, hydraulic presses, shearing machines, injection molding machines, and robotic workcells. These devices are integrated into safety circuits within control panels, often connected to safety relays or programmable safety controllers (e.g., Pilz PNOZ, Siemens Sirius). They are also used in packaging lines, stamping operations, and any application requiring manual intervention near moving parts. The devices support both Category 3 and Category 4 safety architectures per EN ISO 13849-1, making them suitable for high-risk environments.
Our catalog includes subcategories such as two-hand control panels, two-hand control modules, and two-hand pushbutton stations. Key article codes include the EATON M22-PVK series (e.g., M22-PVK4A for 4-contact versions), the SCHMERSAL ZSD series (e.g., ZSD 2 for dual-channel monitoring), and the SIEMENS 3SB3 series (e.g., 3SB3801-0AA1 for two-hand control units). Codes often follow patterns like [Series]-[Contact Configuration]-[Voltage Rating], where contact configuration indicates normally open (NO) or normally closed (NC) contacts. For example, the SCHMERSAL ZSD 2 includes two NC contacts for redundancy.
