The \u201cTWINTOR\u201d connectors adopt JIS Standard colors. Users can use a thermocouple, connector, and extension and compensating cable for thermocouples in the same color; this means that the \u201cTWINTOR\u201d connectors are super heat-resistant connectors that help to prevent problems such as wrong wiring and that ensure safe use by all users. We, as a manufacturer dedicated to supplying extension and compensating cables for thermocouples and duplex insulated thermocouple wire, utilizing our knowledge and technology of measuring thermoelectric temperature that we have accumulated over years, have developed the above thermocouple connectors to facilitate the easy use of thermocouples. &#8220;TWINTOR&#8221; is a registered

What is the minimum number of products to be supplied?<br \/>\nA. You can purchase one product or more. You can purchase one plug, jack, or set.<\/li>\n<li id=\"FAQ02\">Q. Do the colors of the \u201cTWINTOR\u201d connectors comply with the new JIS colors (Category-1 colors defined by JIS)?<br \/>\nA. Some colors comply with the new JIS colors. For popular products, we plan to phase in new colors in compliance with the new JIS colors.<\/li>\n<li id=\"FAQ03\">Q. Does a plug, jack, or set come with any accessories?<br \/>\nA. Each of them comes with rubber packing for routing electric wire.<\/li>\n<li id=\"FAQ04\">Q. Our company is now using imported connectors. Are your connectors interchangeable with the ones we are using?<br \/>\nA. Some of our connectors are interchangeable with imported connectors. However, since imported connectors vary greatly, the interchangeability between our connectors and imported connectors may differ depending on factors such as the time of the production of the imported connectors. Such differences may occur even when the imported connectors are made by a single manufacturer. For details, please contact our Sales Department.<\/li>\n<li id=\"FAQ05\">Q. How can I use cable clamps?<br \/>\nA. Use cable clamps to fix extension and compensating cables for thermocouples and duplex insulated thermocouple wire, which are connected to the \u201cTWINTOR\u201d connectors, to prevent them from coming off.<\/li>\n<li id=\"FAQ06\">Q. Your company is offering two types of cable clamps: Double-end clamps and single-end clamps. What is the difference between them?<br \/>\nA. A double-end clamp fixes an electric wire from both sides. A single-end clamp also fixes an electric wire from both sides, but fixes the \u201cTWINTOR\u201d connector from one side. We recommend using single-end clamps.<\/li>\n<li id=\"FAQ07\">Q. What are the outside diameters of usable conductors of wire and the outside diameters of usable sheaths?<br \/>\nA.

How can I use panel fittings?<br \/>\nA. Use panel fittings to fix \u201cTWINTOR\u201d connectors onto objects such as panels of devices. Insert the attached screws into the eyelet holes of the \u201cTWINTOR\u201d connector to fix it.<\/p>\n<div class=\"al_l\"><img loading=\"lazy\" class=\"alignnone size-full wp-image-257\" src=\"https:\/\/ninomiya-ew.co.jp\/en\/wp-content\/uploads\/2020\/05\/tw_04.jpg\" alt=\"\" width=\"200\" height=\"152\" \/> <img loading=\"lazy\" class=\"alignnone size-full wp-image-258\" src=\"https:\/\/ninomiya-ew.co.jp\/en\/wp-content\/uploads\/2020\/05\/tw_05.jpg\" alt=\"\" width=\"200\" height=\"152\" \/><\/div>\n<\/li>\n<li id=\"FAQ09\">Q.

Insert a square washer between the screw and the \u201cTWINTOR\u201d pin to fix conductors. Two square washers are required for each plug and jack.<\/p>\n<div class=\"al_l\"><img loading=\"lazy\" class=\"alignnone size-full wp-image-259\" src=\"https:\/\/ninomiya-ew.co.jp\/en\/wp-content\/uploads\/2020\/05\/tw_06.jpg\" alt=\"\" width=\"150\" height=\"106\" \/> <img loading=\"lazy\" class=\"alignnone size-full wp-image-260\" src=\"https:\/\/ninomiya-ew.co.jp\/en\/wp-content\/uploads\/2020\/05\/tw_07.jpg\" alt=\"\" width=\"150\" height=\"106\" \/> <img loading=\"lazy\" class=\"alignnone size-full wp-image-261\" src=\"https:\/\/ninomiya-ew.co.jp\/en\/wp-content\/uploads\/2020\/05\/tw_08.jpg\" alt=\"\" width=\"150\" height=\"106\" \/><\/div>\n<p>*In the above photos, the rubber packing is removed to allow the reader to clearly see the square washers.<\/li>\n<li id=\"FAQ11\">Q. Does your company specify torque for tightening screws?<br \/>\nA. The tightening torque that we recommend is \u201capprox. 8.9CN\/m.\u201d The maximum tightening torque that we recommend is \u201capprox. 16CN\/m.\u201d If torque exceeding the maximum tightening torque is applied, the \u201cTWINTOR\u201d connector may break. We recommend using a torque screw driver.<\/li>\n<li id=\"FAQ12\">Q. Do the \u201cTWINTOR\u201d connectors comply with the RoHS Directive?<br \/>\nA. Yes, they do.<\/li>\n<li id=\"FAQ13\">Q. Do the \u201cTWINTOR\u201d connectors comply with the China RoHS?<br \/>\nA. Unlike the EU RoHS Directive, the China RoHS allows the regulation values to be exceeded, but basically requires an indication of whether or not the product contains any of the six specified hazardous substances. A part (an insertion nut that is mainly made of brass) used for the \u201cTWINTOR\u201d connectors contains lead, the content of which exceeds the value regulated in the China RoHS (Note: For the EU RoHS Directive, this is included in the Exemption List). Before bringing a \u201cTWINTOR\u201d connector or a device incorporating a \u201cTWINTOR\u201d connector into China, the user must judge whether the connector or device contains the six specified hazardous substances. When bringing the connector or device into China, the user must present a document which proves whether the connector or device contains the six specified hazardous substances. We can provide a document about the parts of\u201cTWINTOR\u201d that contain the six specified hazardous substances. Therefore, please contact our Sales Department.<br \/>\nNote: The six specified hazardous substances (cadmium, hexavalent chromium, lead, mercury, polybrominated biphenyls [PBB], and polybrominated diphenyl ether [PBDE]) and regulation values (threshold values) that the EU RoHS Directive specifies are the same as those that the China RoHS specifies. However, although the EU RoHS Directive contains the EU RoHS Exemption List which describes that steel materials, aluminum alloy, and copper alloy are exemptions, the China RoHS does not specify such exemptions.<\/li>\n<\/ol>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>The thermocouple connectors, &#8220;TWINTOR,&#8221; are our original products, and there are no other products like these in Japan. The \u201cTWINTOR\u201d connectors adopt JIS Standard colors. Users can use a thermocouple, connector, and extension and compensating cable for thermocouples in the same color; this means that the \u201cTWINTOR\u201d connectors are super heat-resistant connectors that help to prevent problems such as wrong wiring and that ensure safe use by all users. We, as a manufacturer dedicated to supplying extension and compensating cables for thermocouples and duplex insulated thermocouple wire, utilizing our knowledge and technology of measuring thermoelectric temperature that we have accumulated over years, have developed the above thermocouple connectors to facilitate the easy use of thermocouples. &#8220;TWINTOR&#8221; is a registered trademark of our company.<\/p>\n","protected":false},"featured_media":240,"template":"","product_cat":[27],"tew_cat":[],"tcw_cat":[],"temperature":[],"_links":{"self":[{"href":"https:\/\/ninomiya-ew.co.jp\/en\/wp-json\/wp\/v2\/product\/238"}],"collection":[{"href":"https:\/\/ninomiya-ew.co.jp\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/ninomiya-ew.co.jp\/en\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/ninomiya-ew.co.jp\/en\/wp-json\/wp\/v2\/media\/240"}],"wp:attachment":[{"href":"https:\/\/ninomiya-ew.co.jp\/en\/wp-json\/wp\/v2\/media?parent=238"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/ninomiya-ew.co.jp\/en\/wp-json\/wp\/v2\/product_cat?post=238"},{"taxonomy":"tew_cat","embeddable":true,"href":"https:\/\/ninomiya-ew.co.jp\/en\/wp-json\/wp\/v2\/tew_cat?post=238"},{"taxonomy":"tcw_cat","embeddable":true,"href":"https:\/\/ninomiya-ew.co.jp\/en\/wp-json\/wp\/v2\/tcw_cat?post=238"},{"taxonomy":"temperature","embeddable":true,"href":"https:\/\/ninomiya-ew.co.jp\/en\/wp-json\/wp\/v2\/temperature?post=238"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
