Relay contact five wire output proximity switch LJC40-2420GJ Product introduction: Proximity switch is a position switch that can be operated through direct mechanical contact without the need for moving parts. When related objects are approaching the switch, they can sense the action distance, which drives DC electrical appliances or provides a control command to computer devices. It is an ideal electronic switch quantity sensor. Proximity switches are widely used in many industries, especially in industry, and are divided into several categories: passive, photoelectric, capacitive, etc. They can accurately reflect the position and stroke of machine motion mechanisms. Product features: Smooth or threaded stainless steel cylindrical shell reverse polarity protection and short circuit protection LED status indicator M8, M12 connector connection or terminal wiring method PVC, PUR or silicon cable outlet method 2-wire, 3-wire, 4-wire DC, AC, NAMUR output mode and AS-I bus output relay contact five wire output proximity switch LJC40-2420GJ selection:
1. Select proximity switch type according to the detected object. If the detected object is a metal, choose an inductive proximity switch. If the detected object is a non-metal such as wood, plastic, paper, water, or smaller and finer metal, choose a capacitive proximity switch. 2. Appearance selection can be determined based on the installation position of proximity switches, usually including cylindrical proximity switches, square proximity switches, and circular proximity switches. If choosing a cylindrical shape, one should consider the required diameter, and if choosing a square shape, the diameter of the detection surface must also be selected. 3. Selection of sensing distance: Generally speaking, the detection distance of proximity switches is relatively short, with a common range of 1-50mm. The longer the detection distance, the larger the detection surface and the higher the price. 4. The position of the sensing surface usually includes front-end sensing, upper sensing, and inner hole sensing options; 5. Line length selection, standard configuration connection cable length is 2 meters. If a longer connecting wire is needed, it should be explained to the manufacturer before placing an order. However, do not add an extension wire after setting the proximity switch, as this can easily lead to unstable output signals of the proximity switch. 6. Selection of output working voltage, usually available as DC type DC24V or AC type AC250V; 7. Output mode selection, usually available in NPN normally open, NPN normally closed, PNP normally open, PNP normally closed, 2-wire normally open, 2-wire normally closed, DC 3-wire, DC 4-wire options; 8. Connection method selection, available in outlet type, plug-in type, and pigtail type. Some products of Zhuoxin Company:
