www.ZETTLER-group.com page 3 of 4 2024-04-29 NOTES General 1. All values in this datasheet are at reference temperature of 23°C (73°F) unless stated otherwise. 2. Evaluate the component’s performance and operating conditions under the worst -case conditions of the actual application. 3. The datasheet and the component’s specifications are subject to change without notice. Storage, handling, and environmental guidelines 4. Relays are electromechanical components that are sensitive to shock. The relay ’s adjustment can be affected if the relay is subjected to excessive shock or excessive pressure is applied to the relay case. Relays which have been dropped must no longer be used. 5. Substances containing silicone or phosphorus must be avoided in the vicinity to the relay. Outgassing from these substances c an penetrate the relay and adhere on the contacts. Deposits of these substances may act as insulators and adversely affect the contact resistance. S ilicone can be found e.g. in gaskets, lubricants or filling materials, phosphorus can be found e.g. as a flame retardant in plastics. 6. Prevent relays from atmospheres containing corrosive gases. Corrosion of internal structures and contacts leads to malfunctio n a nd shortens the component’s service life. 7. Prevent non-sealed relays from atmospheres subject to dust. Dust particles may enter the case and get stuck between the contacts , causing the contact circuits to fail. 8. Do not use these relays in environments with explosive or flammable gases. Electrical arcing at the contacts could ignite the se gases and cause fire. 9. For automated dual wave soldering process we recommend preheating with 120°C (248°F) for max. 120 seconds and a soldering tem perature of 260 ±5°C (500 ±9°F) for max. 10 seconds soldering time (max. 5 seconds per wave). For manual soldering we recommend 350°C (662°F ) max. temperature for max. 5 seconds. During the soldering process, no force may be exerted on the relay terminals. 10. Non-sealed relays (RTII) must not be washed, immersion cleaned or conformal coated as substances may enter the case and cause co rrosion or seizure of mechanical parts. 11. Avoid high frequency or ultrasonic vibrations on the relays as these can cause contact welding and misalignment or destructio n of internal structures. 12. During operation, storage and transport, ambient temperature should be within the specified operating temperature range. Humi dity should be in the range of 5% to 85% RH. Icing and condensation must be avoided. Relays stored for an extended period of time may show initiall y increased contact resistance values due to chemical effects such as oxidation. Design guidelines 13. The relay may pull in and operate with less than the specified must operate voltage value. 14. The coil’s must operate and min. holding voltages, the coil’s ohmic resistance and the relay’s operate time depend on the temperature of the coil. The specified values are given for a coil temperature of 23°C and increase by approx. 0.39% per Kelvin of temperature rise. This circumstance must be considered, especially during operation with high load currents and elevated ambient temperature. 15. At elevated ambient temperatures, after applying the rated nominal coil voltage for ≥ 200 milliseconds, the coil energization must be reduced to a suitable holding level in order to reduce thermal stress and to prevent the coil from overheating. 16. Coil suppression circuits such as diodes, etc. in parallel to the coil will lengthen the release time. We recommend using sup pression circuits with a breakdown voltage of approx. 2 times the nominal coil voltage in order to achieve a quick release time. 17. When using PWM coil control, use a fast -switching recirculation diode in parallel with the coil to keep the coil current during pulse pauses. To achieve a quick release time when de -energizing the coil, the recirculation diode must be eliminated from the circuit to get a fast decay of coil current. As PWM frequency we recommend ≥ 15 kHz in order to avoid audible noise from magnetostriction. To reduce negative EMI effects, we recommend to apply the PWM to the coil's inner/center layer terminal and have the outer layer terminal connected to ground or the supply rail. 18. Contact resistance is a function of load current, dwell time and wear level of the contacts. Immediately after closing the co ntacts, or if tested with low current only, the contact resistance will show a relatively high value. A low level steady state contact resistance is reache d at higher current after a certain time in thermal equilibrium. 19. The relay dissipates heat form power losses through its load terminals. Provide sufficient cross section and area of the PCB traces so that they can act as heat spreader. 20. For PCBs with multiple relays, do not place the components directly next to each other. We suggest providing a mounting dista nce of minimum 10 mm to allow for better cooling. 21. A minimum load of 10 mA / 5 V / 50 mW is recommended for the gold plated NC signal contact to ensure a reliable and stable el ectrical connection. 22. As with any contact mechanism, the relay ’s NC signal contact bounces when switching. For evaluation of its signal, suitable debouncing measures must be taken to get a reliable signal. Compliance with IEC 62752, IEC 62955 or similar standards for short circuit withstand is a function of both relay design and PCB layout. ZETTLER's relay design and applications engineering teams have developed an application note that contains important design suggestions to op timize the performance of the relay with respect to its short circuit current withstand capability. In addition, as the overall performance depends on multiple factors such as part arrangement and trace routing, compliance ca nnot be generically guaranteed by ZETTLER. We strongly encourage customers to conduct their own short circuit tests in accordance with IEC 62752, IEC 62955 or similar standards in the context of their individual application design.
