The document provides general data and characteristics of the AZ970E/AZ971E relays from ZETTLER electronics GmbH. The relays are known for their long life expectancy, high electrical and mechanical performance, and fast operate and release time.
The AZ970E and AZ971E are compact 40 A miniature power relays designed for automotive use. They offer low cost, vibration‑ and shock‑resistance, and are available with open, covered or sealed styles. Coil voltages up to 24 VDC are supported and the relays provide fast switching times.
The sheet lists electrical ratings, mechanical dimensions, coil specifications and ordering numbers for Form A, B and C contacts. Environmental limits include an operating temperature range of –40 °C to 105 °C and a maximum temperature of 155 °C. Contact resistance, dielectric strength and insulation resistance values are also provided.
