Samples can be arranged for approved buyers.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Quality and inspection<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Production is inspected against the agreed specification before packing, with photographs sent at the pre-shipment stage. If you use a third-party inspection company we coordinate the visit and provide the packing list in advance.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Frequently asked questions<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Capacitive or inductive?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Capacitive senses almost any material including plastics and liquids; inductive only senses metal but is more precise and cheaper. Choose capacitive for non-metal.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Can the sensing distance be adjusted?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Yes, via the potentiometer on the body, which is also how you desensitise it to avoid false trips through thick walls.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Request a quotation<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Email <a href=\"mailto:sales@kaivoy.com\">sales@kaivoy.com<\/a> with the quantity, destination and any specification you need to meet, or use the <a href=\"https:\/\/kaivoy.com\/contact\/\">inquiry form<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Related products<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/kaivoy.com\/micro-electronics\/roller-chain-08b\/\">Roller Chain 08B (per metre)<\/a><\/li>\n\n<li><a href=\"https:\/\/kaivoy.com\/micro-electronics\/m12-4-pin-waterproof-connector\/\">M12 4-Pin Waterproof Connector (IP67)<\/a><\/li>\n\n<li><a href=\"https:\/\/kaivoy.com\/micro-electronics\/gear-motor-750w\/\">Gear Motor 750 W<\/a><\/li>\n\n<li><a href=\"https:\/\/kaivoy.com\/micro-electronics\/inductive-proximity-sensor-m18\/\">Inductive Proximity Sensor M18 (8 mm)<\/a><\/li>\n<\/ul>\n\n\n\n\n<div class=\"kv-quote-cta\" style=\"border:1px solid #e5e7eb;border-radius:12px;padding:24px 26px;margin:38px 0;background:#fafafa\">\n<h2 style=\"margin:0 0 8px;font-size:22px;line-height:1.3\">Request a quotation for Capacitive Proximity Sensor M30 (15 mm)<\/h2>\n<p style=\"margin:0 0 18px;color:#4b5563;font-size:15px;line-height:1.6\">Send us the quantity, the coupler or interface type you need, and your destination port.
