Step away from fragile plastics and power-hungry active sensors. Forged from high-grade stainless steel, the SAIER G1″ Reed Switch Flow Sensor<\/b> is engineered for extreme environments, offering unmatched resistance to chemical corrosion, high pressures, and extreme temperatures. It is the ultimate OEM solution for food processing, RO water filtration, and corrosive fluid management.<\/p>\n

Its true technical advantage lies in the magnetic reed switch mechanism. Operating completely passively with zero standby power<\/b>, it delivers a clean, isolated dry-contact signal. This makes it exceptionally safe and ideal for battery-operated IoT smart farming systems or simple logic alarm circuits. Equipped with a standard 1-meter cable, we offer 100% customizable wire lengths and terminal connectors to seamlessly plug into your production line.<\/p>\n

Engineering Insight: Why Choose a Reed Switch for Your Next Project?<\/h3>\n

While Hall effect sensors are excellent for high-frequency pulse counting, they require continuous power. The SAIER Stainless Steel Reed Switch offers distinct advantages for specific engineering challenges:<\/p>\n\n\n\n\n\n\n
Technical Feature<\/th>\nActive Hall Effect Sensor<\/th>\nSAIER Passive Reed Switch<\/th>\n<\/tr>\n
Power Consumption<\/strong><\/td>\nRequires 5V-24V VCC continuously (Drains batteries).<\/td>\nZero Standby Power. Perfect for solar or battery-operated IoT nodes.<\/strong><\/td>\n<\/tr>\n
Signal Output Type<\/strong><\/td>\nDigital voltage pulse (needs MCU processing).<\/td>\nIsolated Dry Contact (Simple ON\/OFF switch closure).<\/strong><\/td>\n<\/tr>\n
Wiring Complexity<\/strong><\/td>\n3-Wire setup (VCC, GND, Signal).<\/td>\nSimple 2-Wire setup (Polarity independent).<\/strong><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

*Note: Our standard model comes with a 1-meter cable, but we offer full OEM wire harness customization (lengths, shielding, and terminal connectors) to match your specific control board.<\/em><\/p>\n<\/div>","protected":false},"featured_media":6165,"comment_status":"open","ping_status":"closed","template":"","meta":{"_eb_attr":"","jetpack_post_was_ever_published":false,"jetpack_publicize_message":"","jetpack_publicize_feature_enabled":true,"jetpack_social_post_already_shared":true,"jetpack_social_options":{"image_generator_settings":{"template":"highway","default_image_id":0,"font":"","enabled":false},"version":2},"_wpas_customize_per_network":false},"product_brand":[132668],"product_cat":[132613],"product_tag":[132937,132754,132725,132894,132595],"class_list":{"0":"post-6161","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_brand-saier","7":"product_cat-brass-water-flow-sensor","8":"product_tag-flow-sensor-meter","9":"product_tag-liquid-flow-sensor","10":"product_tag-reed-switch","11":"product_tag-water-flow-rate-sensor","12":"product_tag-water-flow-sensor","14":"first","15":"instock","16":"shipping-taxable","17":"product-type-simple"},"yoast_head":"\nG1 Stainless Steel Flow Sensor | Passive Reed Switch | SAIER - Professional manufacturer of sensors<\/title>\n<meta name=\"description\" content=\"Ensure reliability in harsh fluids with SAIER's G1 Stainless Steel Flow Sensor.
