Limit switch (plastic) straight key for LK\291 LK\293K1

Safety and reliability in every circuit

This limit switch, designated catalog number LK\293K1, is a key element ensuring safety and functionality in emergency stop systems. Made of durable plastic, it is designed to work with LK\291 and LK\293K1, offering solid and reliable operation.

Design and operating parameters

The switch is designed to operate in a wide temperature range – from -10°C to +70°C, making it suitable for use in various environmental conditions. The IP65 protection class guarantees resistance to dust and moisture, which is particularly important in demanding industrial conditions. The rated insulation voltage U i is 400V, ensuring safe use.

• Resistance to external factors: Impact resistance (up to 1000 m/s²) and electrical resistance (up to 300 m/s²) make the device resistant to damage during operation.
• Long-term operation: Designed for intensive use – withstands up to 10 million mechanical cycles and 150 thousand electrical cycles.
• Response speed: Adapted to work with connection speeds from 0.1 to 0.5 m/s and a frequency of 30 operations per minute.
• Insulation: Insulation resistance is at least 100 MΩ at 500 VDC, ensuring high electrical insulation efficiency.
• Dielectric strength: AC2500V / Uimp 4KV – high resistance to insulation breakdown.
• Humidity: Operation in humidity conditions below 95% RH does not affect its operation.

This limit switch is a reliable solution for installers and users looking for a safe and durable element of the emergency stop system. Its solid construction and high technical parameters guarantee long-term and trouble-free operation.
