3. Product Performance
- Dual‑pitch design: 3.81 mm wire‑side pitch provides ample screwdriver access; 2.54 mm PCB‑side pitch supports high‑density board layout, balancing wiring convenience and compact PCB footprint.
- Cage‑clamp mechanism delivers constant clamping force after screw tightening. Vibration‑resistant gas‑tight connection prevents loose wiring under industrial conditions.
- 64 integrated channels within one block reduces discrete terminals, simplifies cabinet wiring and minimizes wiring mistakes.
- Full plug‑out capability: entire harness can be disconnected in one step during maintenance, no need to remove wires one‑by‑one, greatly reduces MTTR.
- Flame‑retardant housing, wide operating temperature range, suitable for 7×24 continuous industrial operation.
- Passive connector, protocol‑agnostic, compatible with digital I/O, analog signals and low‑power distribution.
4. Application Fields
- Industrial Automation: I/O interface terminals for servo drives and motion controllers.
- PLC & DCS Systems: Field wiring for high‑density signal acquisition boards.
- Test Equipment & Jigs: Multi‑channel signal harness transition.
- Machine Control Cabinets: Signal aggregation for encoders, brakes and large‑volume sensor wiring.
