SX fan-shaped cylinder+magnetic switch

1、 Working principle of APL limit switch box:

APL limit switch box is a field instrument used in automatic control systems to detect valve status. It detects valve position angle displacement and generates rotation through the transmission shaft, causing the cam to trigger the micro switch, thereby closing or opening the contacts of the switch component. The switch signal is transmitted to the outside through the wiring terminal and displayed locally through the indicator.

2、 APL limit switch box technical specifications:

Protection level IP65 (intrinsic safety type) IP67 (shell protection type)
Contact capacity 6A/24VDC (DC) 10A/220VAC (AC)
Micro switch mechanical, inductive, proximity type
Environmental temperature -35 ℃~+70 ℃
Wiring port 2-G1/2 "
Position indicator on yellow, off red

3、 Installation and use of APL limit switch box:
1. Move the valve to the closed position, adjust the red cam to output a signal from the "close" switch
2. Move the valve to the open position, adjust the red cam to output a signal from the "on" switch
3. Make the valve open and close in place several times to ensure that the limit switch output is stable and reliable
