Owning very strong R&D Center, Senba has become the most advanced pressure transmitter manufacturer specialized in PIR sensor in China. FAQ Is Wave Soldering Recommended? Wave soldering is likely to cause degradation of product performance. Wave soldering is not recommended. Generally we recommend to solder by hand. Can PIR Sensor Detect Animals? PIR sensors are excellent in human and animal detection. They are mostly used in triggering an intruder alarm and activate household appliances upon the presence of a human. Do PIR Sensors Work Through Glass? No, alarm motion sensors do not work through glass. Most motion sensors use passive infrared (PIR) technology to detect motion. Changes in IR energy are not easily detected through glass. This is why motion sensors will generally not work through windows, which are usually insulated. What Is The Package? 1. PIR sensor: Graphic Carton-> Carton 2. LDR: plastic bag -> Graphic Carton -> Carton 3. Fresnel Lens: plastic bag -> Carton What are the Factors that Affect the Performance of the Product? 1. When there is dirt on the window, it will affect the detection performance. 2. When the ambient temperature and the human body temperature are close, the detection and sensitivity are significantly reduced, sometimes causing short- term failure. The recommended minimum temperature difference between the ambient temperature and the human body temperature needs to reach at least 4 ° C. 3. When designing the circuit, pay attention to anti-interference measures to prevent false alarms caused by radio frequency interference.

An Overview of Low pir sensor power consumption Infrared Motion Sensor for Lighting G2X2 G2X2, with the low power pir motion sensor module, is quad elements type products. With same horizontal and vertical detection angles. It is widely used in ceiling light. PIR sensors allow you to sense motion, almost always used to detect whether a human has moved in or out of the sensors range. They are small, inexpensive, low-power, easy to use and don't wear out. For that reason they are commonly found in appliances and gadgets used in homes or businesses. They are often referred to as PIR, "Passive Infrared", "Pyroelectric", or "IR motion" sensors. Features Quad Elements Same horizontal and vertical detection angles Slight movement can be detectable Recommended Model G2X2 Encapsulation Type TO-5 IR Receiving Electrode 1.1×1.1mm, 4 elements Window Size 4.9×4.9mm Spectral Response 7—14µm Transmittance ≥75% Output Signal[Vp-p] ≥3500mV Sensitivity ≥3300V/W Detectivity (D*) 1.4 ×108 cmHz1/2/W Noise[Vp-p] <70mV Output Balance <10% Offset Voltage 0.3～1.2V Supply Voltage 3—15V Operating Temp -30—70ºC Storage Temp -40—80ºC Field of View Applications Ceiling Lighting security systems FAQ 1. What can trigger a PIR sensor? The first cause of PIR false alarms is low or unstable voltage at the detector. Test to make sure the voltage at each PIR is above 13VDC and stable. The second cause of false alarms is sudden infrared movement / heat changes in view of the detector. 2. Do PIR sensors work in the dark? Yes, motion sensors work in the dark. The way that a motion sensor detects movement has nothing to do with how light or dark it is in the immediate area. Since infrared energy is present and can be detected regardless of the amount of light in the environment, a PIR motion sensor will work just fine in the dark. Senba Sensing Technology Co.,Ltd., sets focus on producing top quality photoelectric components, such as passive ir motion sensor, Photoresistors and Light Sensors ,etc. These series of senba sensor are advanced in this field.

Linear Light Sensor, we also call it photoresistor light sensor or phototransistor. The chip integrated inside the ldr light sensor is very sensitive to light changes. So normally it is used to detect the current ambient light level and converts the light energy into an electrical signal output. Compared with traditional photoresistors, this kind of photosensitive resistance sensor is more environment friendly and complied with ROHS requirements. We can also make it to be SMD type with mini size. It is more and more popular now. FAQ Is Wave Soldering Recommended? Wave soldering is likely to cause degradation of product performance.

As one of the leading teflon coated fiberglass cloth manufacturers, Mutiflon provides high-quality high temp fabric worldwide. PTFE coated fabrics are made by fiber glass fabric impregnated with PTFE dispersion on one side ortwo sides, the material combines advantages of PTFE and main features of woven fiberglass fabric. Fiberglass yarn has high strength while light weight, it is twice as strong as stelwire and more cost-effective compared to other synthetic fabric. Typical properties of PTFE are nonstick and temperature resistance. PTFE coating makes the fabric 100% nonstick to any object under low and high temperature between-73-260℃(-100-50OF). The strong mutiply carbon-fluorine bonding structure of PTFE makes it high resistance to solvents, acids, and bases. PTFE fiber is also one of the materials with the lowest coefficient of friction, suitable for applications that require excellent wear resistance. Types of PTFE Coated Fabrics PTFE coated fabrics are made by ptfe teflon coated fiberglass fabric impregnated with PTFE dispersion on one side or two sides,the material combines advantages of PTFE and main features of woven fiberglss abric. Fibrglass yarm has high strength wilelightweight. It is twice as strong as steel wire and more cost-ffctive compared to other synthetic fabric. Standard PTFE coated fabics Standard PTFE coated fabics contain the highest level of PTFE which will provide quicker release property, widely used as release sheet for heat press laminating machine or making into a conveyor belt for drying and baking. PTFE glass mesh fabric Teflon coated fiberglass mesh also called PTFE open mesh fabrics are made from open mesh woven fiberglass coated with PTFE, the open mesh allows air and heat pass through quickly to improve drying time. PTFE coated Kevlar fabric PTFE coated Kevlar fabric also called PTFE coated Aramid fabrics is structured by woven Kevlar fabric or Kevlar mesh coated with PTFE. There are two unique advantages of PTFE coated Kevlar fabrics. PTFE Coated Fabrics FAQs What is PTFE? A. PolyTetraFluoroEthylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene, it was firstly developed by Dupont™ in a brand name of Teflon®, PTFE is used as a non-stick coating and provide chemical corrosion resistant, friction reduction and high heat resistance. How long are the length of PTFE coated fabrics rolls? A. Normal length of our rolls are 30m, 50m or 100m. Special arrangements can be made for longer or shorter length rolls, please contact us. How wide are the PTFE coated fabrics? A. It is depend on the thickness of PTFE coated fabrics. Normally max width is 2600mm, small width like 20mm, 50mm can easy to cut. For the PTFE coated open mesh type, max width reach to 4000mm. Please contact us for more info. Do you have a minimum order amount? A. Yes, normally we have $100.00 minimum order for PTFE coated fabrics, PTFE adhesive tapes and PTFE conveyor belts. How is your PTFE Coating? A. Mutiflon uses PTFE in the form of water-based (aqueous) dispersion to coat glass fibre cloth (usually referred to as glass cloth, or simply “glass”), Kevlar® and woven wire. This high performance substrates support the polymer additional dimension stability and mechanical strength. Only materials which stand the very high processing and application temperatures can be coated. A variety of techniques can be used in processing to improve the tear strength and resistance to creasing of the finished fabric, provide conductivity (anti- static properties), or resistance to oil and fats.

General Description of Prepainted Galvanized Steel Coil Pre-coated coil is a product obtained by chemical surface treatment (coating) of hot-dipped galvanized steel, galvanized steel coil or aluminum, followed by baking and curing. the total thickness of the prepainted galvanized steel coil consists of the thickness of the base steel -- coating -- primer -- topcoat -- protective coating. The top coating is 10-25 microns thick and the back coating is 5-20 microns thick. The thinner the basic steel thickness, the higher the price of PPGI steel coil, because the processing cost will be higher. usually, the paint material is polyester (PE) and the back paint color is white and gray. Colors can be customized according to RAL color CARDS or customer samples. Can make special patterns, such as wood grain, flower pattern, camouflage, brick.
