Application Scenarios

This Industrial Power Relay is engineered for mission-critical applications where failure is not an option:

  • Drone & UAV Systems: Flight controller power switching, payload activation, and safety circuit management
  • Aircraft Avionics: Engine control units, fuel system management, and auxiliary power distribution
  • Military Vehicles: Communication system switching, weapon system control, and surveillance equipment
  • Industrial Automation: High-reliability control panels, safety interlock systems, and precision instrumentation
  • New Energy Systems: Battery management systems and power distribution in electric vehicles and renewable energy installations

How to Integrate This Relay

  1. Circuit Verification: Confirm your PCB layout matches the DPDT 8-pin configuration of the JQX-3Z25BM
  2. Soldering Preparation: Use temperature-controlled soldering equipment (recommended: 350°C max) with lead-free solder
  3. Mounting: Secure the relay to the PCB board using appropriate mounting hardware if required
  4. Connection Check: Verify coil polarity and contact assignments according to your schematic diagram
  5. Testing Protocol: Perform functional testing at both nominal (27V) and specified tolerance voltages
  6. Environmental Sealing: Apply conformal coating if additional environmental protection is needed beyond the relay's built-in sealing

Quality-Assured Production Process

Every YM Relay undergoes our stringent 8-stage manufacturing protocol:

  1. Raw material inspection (SUS304/SUS316 stainless steel verification)
  2. Precision stamping and forming of metal components
  3. Automated coil winding with precision tension control
  4. Contact assembly with precious metal alloys for optimal conductivity
  5. Hermetic sealing in controlled atmosphere chambers
  6. 100% electrical and functional testing at three temperature points
  7. Environmental stress screening (vibration, thermal shock, moisture resistance)
  8. Final inspection and lot traceability documentation

Frequently Asked Questions

Q1: What makes this a "military-grade" relay compared to standard industrial relays?

A1: Military-grade designation requires passing stringent tests for shock (up to 100G), vibration (20-2000Hz), extreme temperatures (-65°C to +125°C), and hermetic sealing. Our relays undergo these tests with documentation available.

Q2: Can this relay be used as a direct replacement for LEACH M500 or DEUTSCH E325 series?

A2: Yes, the JQX-3Z25BM is designed as a pin-compatible replacement for both series, though we recommend verifying specific application parameters with our engineering team.

Q3: What is the lead time for production quantities?

A3: Standard products ship within 2-3 weeks. Customized Solid State Relay or Intermediate Power Relay variants may require 4-6 weeks for tooling and qualification.

Q4: Do you offer samples for qualification testing?

A4: Yes, we provide up to 3 free samples for qualified B2B customers. Freight is arranged collect via your courier account (DHL, FedEx, or UPS).

Q5: What warranty do you provide on these relays?

A5: We offer a 10-year mechanical warranty and 2-year electrical performance warranty when used within specified parameters.
