SMC CDQ2B50 Horizontal Stopper Cylinder (CJQC0757 / CJVC0940)

SMC CDQ2B50 Horizontal Stopper Cylinder (CJQC0757 / CJVC0940)

SMC Korea CDQ2B50 horizontal stopper cylinder (special CJQC0757 / CJVC0940), a ø50 mm compact cylinder driven low-profile stopper with adjustable shock absorber for stopping heavy loads on high-speed conveyor lines.

Key features

  • Stops heavy transported loads smoothly at high line speed; adjustable shock absorber sets absorbed energy (shipped set to 0)
  • Low height mounts on the conveyor without extra holes beneath, reducing installation cost
  • Lever linkage keeps lateral load off the cylinder for long durability
  • Heavy-load (H, KCA42-25-SM) or medium-load (M, KSA36-25BN-SM) shock absorber; cylinder port on left (L) or right (R)
  • CJQC0757: optional stop lock (self-holding) SL; CJVC0940: optional proximity sensor bracket (D), limit switch bar (E) or bracket (F), stop lock (SL) or bypass lock (BL)
  • Built-in magnet (CDQ2) for auto switch detection
