DXZ limit switch has some character as sensitive structure, small volume, multi-function, high accuracy, moveable, strong communicate and installation convenience. It uses moveable mechanical form, performance credibility and

high acuity, it can carries out double speed-down (warning) and limits.

Meanwhile it can installed electro-signal of sensor on type ZXY display meter and instantaneous distance of travel come true (for example : height and scope)

Security of limit switch as follow:

a: raising over low limit and protection

b: raising over high limit and protection

c: scope towards front speed-down

d: scope towards behind speed-down and protection

e: turn-back positive and negative limit protection

DXZ limit switch divide drive rate as 1: 13-960, eight specification in all, control loop 1-4 PCS (Non-standard can reach 6 PCS), repeat positioning accuracy≤0.3(turning angle error of memory cam).

Drive rate No.
