Metal Inductive Switch Proximity Sensor NPN 3 Wire Normally Open LJ30A3 10 Z BX, Adjustable Detection Distance, Suitable for Machinery, Mining, Metallurgy

Specification: Item Type: Metal Inductive Switch Model: LJ30A3-10-Z/BX Power Supply Voltage: 6-36VDC Detection Distance: Approx. 10mm / 0.4in Detection Object: Metal object Sensor Diameter: Approx. 30mm / 1.2in Output Mode: NPN NO DC 3-wire type Sensing Direction: Front Output Current: 300MA Cable Length: Approx. 1.1meter / 3.6ft Product Size: Approx. 58 x 30mm / 2.3 x 1.2in How to Use: Capacitive proximity switches can not only detect metal, but also plastic, glass, water, oil and other substances. Due to the difference in conductivity, dielectric constant, water absorption, and volume of various detected substances, the corresponding detection distance is also different. For grounding metal can get the maximum detection distance. packing list: 5 x Metal Inductive Switch Note: 1. DC power supply must use insulating transformer, do not use autotransformer. 2. Strictly forbidden to connect with electricity, strictly follow the color code on the wiring diagram. 3. If there is a power line, and the power line passes near the of the switch, in order to prevent the switch from malfunctioning and damage, please use metal pipe wiring. 4. AC proximity switches are generally not suitable for parallel or series use. It is recommended to switch to a series of relays and use them in parallel. 5. The AC type switch must be connected to the power supply through the load. If the switch is directly connected to the power supply, the switch will be damaged. 6. The length of the proximity switch should be less than 200 meters to avoid excessive voltage drop.

• Suitable for multiple controls such as machine tool limit, detection, counting, speed measurement, liquid level, automatic line for positioning and signalling, etc.
• Capacitive proximity switches can not only detect metal, but also plastic, glass, water, oil and other substances
• Widely used in machinery, mining, metallurgy, plastics, textile, electric power, railway, military and other sectors
• The operating distance of the capacitive proximity switch is generally adjustable to suit the detection of different detection objects
• The maximum detection distance can be obtained for grounded metals, very practical to use
