Product General Introduction

Core Technical Advantages

  1. Terminal strips & spring terminals: BK series direct mount terminals simplify internal equipment wiring; DLD/DLI SNAP IN spring terminals enable tool-free fast wiring, reduce assembly time, and support repeated disassembly.
  2. Crimping tool portfolio: Complete range covering miniature ferrules up to large power cable lugs; ratchet self-locking structure ensures consistent crimp quality, complies with DIN crimp standards.
  3. DK DIN rail electronic modules: Compact 12 mm width, unified TS35 mounting, integrate logic gates and time delay functions to reduce external auxiliary relay quantity inside control cabinets.
  4. D-SERIES industrial relays: DRH equipped with blow-out magnet for reliable breaking of high inductive DC loads; DRL standard multi-contact models realize multi-channel signal switching. Optional LED and surge suppression to protect front-end control equipment.
  5. Service accessories: Universal cross-key, marking printer cable and heavy connector coding pins solve standardised cabinet assembly, anti-misconnection and maintenance demands.
  6. All products comply with CE, UL and RoHS standards; terminal plastic housings are UL94 V-0 flame retardant, suitable for continuous operation in industrial control cabinets.

Application Scenarios

Widely used in machine tool control cabinets, packaging machinery, new energy equipment, water treatment and process automation control boxes:

  1. BK terminal strips: Internal wiring of electrical control boxes without DIN rail installation;
  2. DLD / DLI spring terminals: High-density sensor and actuator signal wiring for compact control cabinets;
  3. CTI / CTX crimping tools: Pre-processing of wire-end ferrules and cable lugs for cabinet assembly workshops;
  4. DK electronic function modules: Realise signal logic judgment and time sequence control without additional PLC programming;
  5. DRH / DRL plug-in relays: Electrical isolation between PLC outputs and on-site inductive loads; DRH variant preferred for DC brake and high-inductance DC load control;
  6. DSTV COST4 coding pins: Heavy-duty industrial connector anti-misplug protection for robot and servo equipment;
  7. Marking tools & universal unlocking key: Standardised cabinet production line wiring, marking and on-site equipment maintenance.
