  • Degree of Protection: IP67 as per EN60947-5-1.
  • Rated Frequency: 50/60Hz.
  • Maximum Voltage: 1500V (EN60947-5-1).
  • Operating Temperature: -40°C to +80°C (without icing).
  • Operating Humidity: Up to 95% RH.
  • Electric Shock Protection Class: Class I with ground terminal.
Mechanical and Electrical Characteristics:
  • Operating Speed: 1 mm/s to 0.5 m/s.
  • Insulation Resistance: 100MΩ minimum.
  • Contact Resistance: 25mΩ maximum (initial value).
  • Durability: 30,000,000 operations minimum for snap-action, 10,000,000 operations minimum for slow-action.
  • Operating Frequency: 120 operations/min for mechanical, 30 operations/min for electrical.
Models and Operating Characteristics:
  • SL4B-00, SL4B-20, SL4B-21, SL4B-40: Standard pin plunger, vertical standard roller lever, top roller plunger, and top crossroller plunger models with varying operating forces and movements.
  • SL4B-50, SL4B-66, SL4B-80, SL4B-81: Adjustable rod lever, adjustable roller lever, coil spring, and plastic rod models with specific operating forces and movements.
Additional Notes: The initial values of characteristics may vary depending on the model. The durability values are based on an ambient temperature of 5 to 35°C and humidity of 40% to 70% RH. For specific requirements, contact the DECA sales representative.
