Frequently Asked Questions
Q1: What is the practical advantage of polarized versus standard relays?
A1: Polarized relays only operate with correct current direction, preventing accidental activation from wiring errors, induced voltages, or system faults that could cause reverse polarity - a critical safety feature in aerospace applications.
Q2: How does the RG4.522.107 differ from .102 and .120 variants?
A2: While all share the same basic polarization technology, variants differ in specific sensitivity characteristics, response times, or mounting configurations. The .107 version is engineered to provide optimal performance where the highest polarization reliability is required.
Q3: What happens if reverse polarity is accidentally applied?
A3: The relay will not operate - it remains in its default state. This fail-safe behavior prevents dangerous misoperations in critical control systems. The relay is designed to withstand occasional reverse polarity without damage.
Q4: Can polarized relays replace non-polarized relays in existing systems?
A4: Only if the system provides correct polarity. If existing wiring polarity is unknown or variable, circuit modification may be required. Our technical team can provide guidance for specific replacement scenarios.
Q5: Are samples available for polarization testing?
A5: Yes, we provide up to 3 free samples for qualified B2B customers. Polarization testing requires simple DC power supply with polarity reversal capability for comprehensive evaluation.
Q6: What is the lead time for RG4.522 series relays?
A6: Standard RG4.522.107 configuration: 3-4 weeks. Custom polarization configurations: 4-5 weeks. Bulk orders for safety-critical applications receive priority manufacturing attention.
