Product catalog summary
Overview: The document provides technical specifications for a PCB relay with forcibly guided contacts, compliant with EN 50205 type B. It is designed for medium-duty switching, particularly suitable for DC loads, and is used in safety applications.
Specifications:
  • Contact Configuration: 2 CO (DPDT) contacts with high physical separation.
  • Rated Current/Voltage: 8 A/250 V AC, with a maximum peak current of 15 A and maximum switching voltage of 400 V AC.
  • Contact Material: Available in AgNi and AgNi + Au for low-level switching capability.
  • Coil Specifications: Nominal DC voltages range from 5 V to 125 V, with a rated power of 0.7 W.
  • Insulation: 8 mm, 6 kV isolation between coil and contacts, with reinforced insulation according to EN 61810-1.
Technical Data:
  • Mechanical Life: 10 million cycles for DC.
  • Electrical Life: 100,000 cycles at rated load AC1.
  • Operating Temperature: -40°C to +70°C.
  • Environmental Protection: Flux proof (RT II).
Performance:
  • Breaking Capacity: DC1 breaking capacity varies with voltage, with a minimum switching load of 500 mW.
  • Vibration and Shock Resistance: Vibration resistance up to 20 g for NO contacts and 6 g for NC contacts; shock resistance up to 20 g for NO contacts and 5 g for NC contacts.
Ordering Information: The relay is identified by a series of codes indicating the series, type, number of poles, coil version, coil voltage, contact material, contact circuit, and special versions.
Key Recommendations:
  • For DC13 loads, use a diode in parallel with the load to achieve similar electrical life as DC1 loads.
  • Maintain a recommended distance of ≥ 5 mm between relays mounted on a PCB.
