MK31-B-3 - STANDEXMEDER

MK31-B-3 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout and land pattern for the MK31-B-3?
  The recommended PCB layout and land pattern for the MK31-B-3 can be found in the Standex-Meder Electronics' application note AN-105, which provides detailed guidelines for PCB design and layout considerations.
• How do I ensure reliable operation of the MK31-B-3 in high-vibration environments?
  To ensure reliable operation of the MK31-B-3 in high-vibration environments, it is recommended to follow the mounting and soldering guidelines provided in the datasheet, and to consider using a relay socket or a relay with a built-in vibration-resistant design.
• What is the maximum switching frequency of the MK31-B-3?
  The maximum switching frequency of the MK31-B-3 is not explicitly stated in the datasheet, but it is typically limited by the relay's mechanical switching time, which is around 1-2 ms. As a general rule, it is recommended to limit the switching frequency to 1-5 Hz to ensure reliable operation.
• Can the MK31-B-3 be used in high-temperature environments?
  The MK31-B-3 is rated for operation up to 85°C, but it can be used in high-temperature environments with some derating. It is recommended to consult with Standex-Meder Electronics' application engineers to determine the suitability of the relay for specific high-temperature applications.
• How do I determine the coil resistance of the MK31-B-3?
  The coil resistance of the MK31-B-3 can be determined by measuring the DC resistance of the coil using a multimeter. The typical coil resistance is around 100-150 ohms, but it may vary depending on the specific relay and operating conditions.
