Important note

IPC conformity
Conformity: The products are developed, manufactured and delivered according international recognized standards and norms and comply with the assured properties in the data sheet resp. fulfill decorative properties in accordance with IPC-A-610 "Class 2". Further claims on the products can be evaluated on request. 
Notes
  • Gold-plated contact surfaces on request
  • Rated current related to rated cross-section & min. No. of poles.
  • Diameter of solder eyelet D = 1.4+0.1mm
  • Solder eyelet diameter D = 1.5 + 0.1 mm, from 9 poles
  • P on drawing = pitch
  • Rated data refer only to the component itself. Clearance and creepage distances to other components are to be designed in accordance with the relevant application standards.
  • In accordance with IEC 61984, OMNIMATE-connectors are connectors without breaking capacity (COC). During designated use, connectors are not allowed to be engaged or disengaged when live or under load
  • Long term storage of the product with average temperature of 50 °C and maximum humidity 70%, 36 months
