Quick Guide to Push-Pull Self-Locking Connectors: Core Applications & Selection Tips for B/K/S/F/P Series

Facing the B, K, S, F, and P series of mainstream push-pull self-locking connectors, how can you quickly identify the right model? This guide cuts through the noise to highlight the key features of each series, helping you finalize your selection in 3 minutes.

1. B Series: The All-Rounder for General Use

Key Applications: Industrial control, test equipment, broadcasting & film

Selection Highlights:
✅ Multi-Core Hybrid: Supports 2–26 cores (power + signal + coaxial), ideal for complex device interfaces.
✅ IP68 Protection: Dustproof and waterproof for outdoor devices (e.g., industrial sensors, OB vans).
✅ Cost-Effective: Balances performance and cost, perfect for bulk purchases.

Avoid This Pitfall: Use shielded versions (e.g., B.00 series) for high-frequency signal transmission.

2. K Series: The Miniaturization Specialist

Key Applications: Medical endoscopes, drones, portable instruments

Selection Highlights:
✅ Ultra-Compact Design: Diameter as small as 3.5mm, fitting tight spaces (e.g., miniature surgical tools).
✅ High-Speed Stability: Supports 10Gbps data transfer for 4K/8K video.
✅ Lightweight: Plastic housing reduces weight by 30%, extending device battery life.

Avoid This Pitfall: Choose metal-shell versions (e.g., gold-plated contacts) for high-current scenarios.

3. S Series: The Powerhouse for High Current

Key Applications: Electric vehicles, robots, military equipment

Selection Highlights:
✅ High Power Capacity: Single core supports 200A, ideal for charging stations and servo motors.
✅ Vibration-Resistant: Dual-locking structure passes MIL-STD-810G vibration tests.
✅ Wide Temperature Range: -55°C to +200°C for extreme environments (e.g., polar expeditions).

Avoid This Pitfall: Pair with hybrid S.B series models for multi-core needs.

4. F Series: The High-Speed Pioneer for Fiber Optics

Key Applications: Data centers, 5G base stations, laser equipment

Selection Highlights:
✅ Low Insertion Loss: ≤0.2dB, supports single-mode/multi-mode fiber.
✅ High Density: Fits 48 cores in 1U rack space, saving 50% room.
✅ EMI Shielding: Metal housing blocks electromagnetic interference for clean signals.

Avoid This Pitfall: Opt for IP67-rated versions (e.g., F.02 series) for outdoor use.

5. P Series: The Crossover King for Hybrid Needs

Key Applications: Hybrid devices (e.g., medical CT scanners, industrial robots)

Selection Highlights:
✅ Multi-Protocol Support: Combines power, signal, fiber, and fluid transmission in one plug.
✅ Modular Design: Customizable pin layouts shorten R&D cycles.
✅ Blind-Mating Ready: 360° rotation locking for tight spaces.

Avoid This Pitfall: Confirm lead times with suppliers for customized orders (longer delivery for P series).

3-Step Selection Process

1️⃣ Define the Scenario: Identify device usage (e.g., medical → K/P, industrial → B/S).
2️⃣ Verify Parameters: Match current, core count, and protection level (e.g., high current → S.B series).
3️⃣ Check Supplier Capabilities: Confirm local inventory, customization options, and after-sales support.

Conclusion: Selecting push-pull self-locking connectors doesn’t have to be complicated. Focus on scenario fit + parameter match to streamline your choice. The B series is reliable, the K series is compact, the S series handles power, the F series excels in speed, and the P series bridges gaps—which one fits your device?
