With a nominal rated output of 1.6 mV\/V and a non-linearity of \u00b10.5% RL, it offers accurate and repeatable results. Versions with rationalised outputs ensure interchangeability across installations.<\/p>\n<h6>Usage conditions<\/h6>\n<p>Suitable for environments with temperatures between -10\u00b0C and +80\u00b0C, the sensor is IP65-sealed, offering protection against dust and splashes. Safe and ultimate overload ratings of 50% and 100% of rated load respectively ensure durability under demanding conditions.<\/p>\n<h6>Possible applications<\/h6>\n<ul>\n<li>OEM force measurement in automation systems<\/li>\n<li>Testing rigs and lab experiments<\/li>\n<li>Control systems in industrial processes<\/li>\n<li>Integration in mobile or static setups<\/li>\n<li>Monitoring systems in confined assemblies<\/li>\n<\/ul>\n<h6>Advantages of choosing this product<\/h6>\n<p>The ALF251 offers unparalleled flexibility in tight spaces, thanks to its miniature load button design. Its bidirectional calibration options, multiple ranges (from 100N to 3.2kN), and fast integration make it a preferred solution for test engineers and OEM developers alike.<\/p>\n<h6>Other important features<\/h6>\n<ul>\n<li>Available in aluminum (up to 200N) or stainless steel<\/li>\n<li>Easy installation with standard threaded versions<\/li>\n<li>Custom designs available upon request<\/li>\n<li>2-meter shielded cable included<\/li>\n<li>Rationalisation capsule integrated in cable for rationalised models<\/li>\n<\/ul>\n<h6 id=\"technical-specifications-title\">Technical Specifications<\/h6>\n<div class=\"rounded border border-gray-line\/20 overflow-hidden\">\n<table class=\"!my-0\">\n<thead class=\"sr-only\">\n<tr>\n<th>Specification<\/th>\n<th>Value<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<th class=\"align-top\">Non-linearity &#8211; Terminal<\/th>\n<td>\u00b10.5 % RL<\/td>\n<\/tr>\n<tr>\n<th class=\"align-top\">Hysteresis<\/th>\n<td>\u00b10.5 % RL<\/td>\n<\/tr>\n<tr>\n<th class=\"align-top\">Creep &#8211; 20 minutes<\/th>\n<td>\u00b10.1 % AL<\/td>\n<\/tr>\n<tr>\n<th class=\"align-top\">Repeatability<\/th>\n<td>\u00b10.1 % RL<\/td>\n<\/tr>\n<tr>\n<th class=\"align-top\">Rated output &#8211; Nominal<\/th>\n<td>1.6 mV\/V<\/td>\n<\/tr>\n<tr>\n<th class=\"align-top\">Rated output &#8211; Rationalised<\/th>\n<td>1.0 mV\/V<\/td>\n<\/tr>\n<tr>\n<th class=\"align-top\">Rationalisation tolerance<\/th>\n<td>\u00b10.5 % RL<\/td>\n<\/tr>\n<tr>\n<th class=\"align-top\">Zero load output<\/th>\n<td>\u00b14 % RL<\/td>\n<\/tr>\n<tr>\n<th class=\"align-top\">Temp. effect on output per \u00b0C<\/th>\n<td>\u00b10.005 % AL<\/td>\n<\/tr>\n<tr>\n<th class=\"align-top\">Temp. effect on zero per \u00b0C<\/th>\n<td>\u00b10.03 % RL<\/td>\n<\/tr>\n<tr>\n<th class=\"align-top\">Temp. range &#8211; Compensated<\/th>\n<td>-10 to +50 \u00b0C<\/td>\n<\/tr>\n<tr>\n<th class=\"align-top\">Temp. range &#8211; Safe<\/th>\n<td>-10 to +80 \u00b0C<\/td>\n<\/tr>\n<tr>\n<th class=\"align-top\">Excitation voltage &#8211; Recommended<\/th>\n<td>10 V<\/td>\n<\/tr>\n<tr>\n<th class=\"align-top\">Excitation voltage &#8211; Maximum<\/th>\n<td>10 V<\/td>\n<\/tr>\n<tr>\n<th class=\"align-top\">Bridge resistance<\/th>\n<td>350 \u03a9<\/td>\n<\/tr>\n<tr>\n<th class=\"align-top\">Insulation resistance (min. @50Vdc)<\/th>\n<td>500 M\u03a9<\/td>\n<\/tr>\n<tr>\n<th class=\"align-top\">Safe overload<\/th>\n<td>50 % RL<\/td>\n<\/tr>\n<tr>\n<th class=\"align-top\">Ultimate overload<\/th>\n<td>\u00b10.03, % RL<\/td>\n<\/tr>\n<tr>\n<th class=\"align-top\">Temperature range &#8211; compensated<\/th>\n<td>100 % RL<\/td>\n<\/tr>\n<tr>\n<th class=\"align-top\">Sealing<\/th>\n<td>IP65<\/td>\n<\/tr>\n<tr>\n<th class=\"align-top\">Weight (excluding cable)<\/th>\n<td>8 to 12 g<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Compact and reliable loadcell for measuring tension and compression forces in tight installation spaces.
