SIM3 Series

SIM3 Series

Product catalog summary
Overview: The SIM3 Series relays by ELESTA GmbH are designed with forcibly guided contacts compliant with IEC 61810-3 standards, suitable for print mounting, and feature protective separation. The SIM212 model includes a contact assembly of 2 NO (Normally Open) and 1 NC (Normally Closed) contacts.
Specifications:
  • Dimensions: Pin dimensions are 1.0 x 0.3 mm and 1.0 x 0.4 mm, with a recommended PCB drilling diameter of 1.3 mm.
  • Coil Data: Nominal power is 0.75 W, with a holding power of 0.21 W and a coil limit temperature of 120 °C. Nominal voltages range from 5.0 VDC to 110.0 VDC.
  • Insulation Data: Rated insulation voltage is 250 VAC, with various air and creepage distances and test voltages for basic and reinforced insulation.
  • Mechanical Data: The relay has a mechanical lifetime of at least 10 million operations, a maximum switching frequency of 15 Hz, and a weight of approximately 25 g.
  • Environmental Data: Operates within an ambient temperature range of -40 °C to +70 °C, with a thermal resistance of 55 K/W.
Contact Data:
  • Contact material is AgSnO2 with a gold layer of 0.2 to 0.4 μm.
  • Rated switching power is 2,000 VA, with a maximum switching voltage range of 5 to 250 V DC/AC.
  • Electrical life expectancy is 100,000 operations at 0.1 Hz with a relative duty cycle of 10%.
Approvals and Standards: The relays are approved by cULus and TÜV, with a flammability class of UL 94 V-0.
Options and Accessories: Available accessories include mounting rail socket SRD SIM4 and PCB socket SRP SIM4, with other coil designs possible.
