SIM2 Series

SIM2 Series

Product catalog summary
Features
The SIM2 Series relays feature forcibly guided contacts compliant with IEC 61810-3, suitable for print mounting, and offer protective separation. The contact assembly for SIM112 includes 1 NO (Normally Open) and 1 NC (Normally Closed) contact.

Dimensions and Mounting
Pin dimensions are specified as 1.0 x 0.3 mm and 1.0 x 0.4 mm, with a recommended PCB drilling diameter of 1.3 mm. The relay can be mounted in any position with a minimum mounting distance of 5 mm.

Coil Data
At 20°C, the nominal power is 0.5 W, and the holding power is 0.15 W. The coil limit temperature is 120°C. Nominal voltages range from 5 VDC to 110 VDC, with corresponding minimum pick-up and drop-out voltages, nominal currents, and resistances provided.

Insulation Data
The rated insulation voltage is 250 VAC, with double or reinforced insulation requiring a minimum air and creepage distance of 5.5 mm and 14 mm, respectively. Test voltages are 4,000 Vrms and 5,000 Vrms for 1 minute. The insulation resistance is at least 100 MΩ.

Mechanical Data
The relay has a mechanical lifetime of at least 10 million operations, with a maximum switching frequency of 15 Hz. Response and drop-out times are 10 ms and 3 ms, respectively. The relay is resistant to shock and vibration, with specified limits for NO and NC contacts.

Environmental and Other Data
The operating ambient temperature ranges from -40°C to +70°C, with a thermal resistance of 55 K/W. The protection class is RT II, and the relay is approved by cULus and TÜV, with a flammability class of UL 94 V-0.

Contact Data
Contacts are made of AgSnO2 with a gold layer, supporting a rated switching power of 2,000 VA. The electrical life is 100,000 operations at 0.1 Hz. The relay can handle inrush currents up to 20 A for 20 ms and supports a switching voltage range of 5 to 250 V DC/AC.

Approvals and Options
The relay is approved by cULus and TÜV, with options for other coil designs. The product key provides details on type designation, number of contacts, connection technology, and nominal coil voltage.
