An operator who places a part on the sensor carelessly, or who accidentally exceeds the measurement range, can permanently damage a standard sensor.<\/p>\n<p>The Mini SEJ-Z&#8217;s mechanical stop resolves this issue by mechanically limiting the deflection of the sensing element as soon as the overload exceeds the protection threshold\u2014without any operator intervention, without electronics, and with no response time. This is a passive protection system that works even in the event of a sudden, instantaneous overload.<\/p>\n<p>This feature significantly extends the sensor&#8217;s service life in a production environment and reduces maintenance costs associated with replacing damaged load cells.<\/p>\n<p>&nbsp;<\/p>\n<div class='content-column one_half'><h3><strong><span style=\"color: #215876;\">Benefits<\/span><\/strong><\/h3>\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li><strong><strong><strong><span style=\"color: #215876;\">Tension &#038; compression<\/span><\/strong><\/strong><\/strong><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li><strong><strong><strong><span style=\"color: #215876;\">Capacities from 1 N \u00e0 5 N<\/span><\/strong><\/strong><\/strong><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li><strong><span style=\"color: #215876;\">Mechanical stop<\/span><\/strong><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p>&nbsp;<\/p><\/div>\n<div class='content-column one_half last_column'><img decoding=\"async\" class=\"alignnone size-full wp-image-6692\" src=\"https:\/\/www.acrn.fr\/wp-content\/uploads\/2021\/07\/mini-sej-z.png\" alt=\"mini-sej-z\" width=\"500\" height=\"300\" srcset=\"https:\/\/www.acrn.fr\/wp-content\/uploads\/2021\/07\/mini-sej-z.png 500w, https:\/\/www.acrn.fr\/wp-content\/uploads\/2021\/07\/mini-sej-z-480x288.png 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) 500px, 100vw\" \/><\/div><div class='clear_column'><\/div>\n<h3>Options<\/h3>\n<ul>\n<li>Rings and hooks<\/li>\n<li>Load button<\/li>\n<li>Longer length for cable<\/li>\n<\/ul>\n<p><img decoding=\"async\" class=\"size-full wp-image-5478 aligncenter\" src=\"https:\/\/www.acrn.fr\/wp-content\/uploads\/2021\/05\/Mini-SEJ-Z.png\" alt=\"Mini-SEJ\" width=\"700\" height=\"500\" srcset=\"https:\/\/www.acrn.fr\/wp-content\/uploads\/2021\/05\/Mini-SEJ-Z.png 700w, https:\/\/www.acrn.fr\/wp-content\/uploads\/2021\/05\/Mini-SEJ-Z-480x343.png 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) 700px, 100vw\" \/><\/p>\n<p>For use with:<\/p>\n<p><a href=\"https:\/\/www.acrn.fr\/en\/product\/sensor-measurement-xa\/\">The XA-m measurement console<\/a> \u2014 Recommended console for reading and storing data measured by the Mini SEJ-Z.<br \/>\n<a href=\"https:\/\/www.acrn.fr\/en\/product\/high-precision-force-sensor\/\">The high-precision SEJ force sensor<\/a> \u2014 For applications requiring higher tensile and compressive capacities (15 daN to 3000 daN).<br \/>\n<a href=\"https:\/\/www.acrn.fr\/en\/product\/compression-cell\/\">The FJ Miniature Load Cell<\/a> \u2014 For compression-only applications with capacities ranging from 100 N to 200 kN.<br \/>\n<a href=\"https:\/\/www.acrn.fr\/en\/calibration-metrology\/\">Our Calibration Service<\/a> \u2014 Periodic calibration of the Mini SEJ-Z in accordance with ISO 17025 methods in our laboratory.<\/p>\n","protected":false},"excerpt":{"rendered":"<blockquote><p>Low range load cell with mechanical stop<br \/>\nCapacity from 1 to 5N<\/p><\/blockquote>\n<p>The Mini SEJ-Z low-force sensor is a miniature aluminum alloy load cell designed to measure extremely low forces (1 to 5 N) in both tension and compression. This is the ideal instrument for applications where the forces to be measured are too small to be accurately detected by standard sensors.<\/p>\n<p>Its key technical feature is its built-in mechanical stop: in the event of accidental overload (up to 100 N for the 1N and 2N models, and up to 500 N for the 5N model), the stop absorbs the force without damaging the sensing element. This protection is critical in test environments where mishandling may occur, and prevents premature replacement of the sensor.<\/p>\n<p>Its very compact dimensions (48 \u00d7 40 \u00d7 48 mm for the 1N and 2N models) allow it to be integrated into test setups with limited space.
