This part is used as a replacement pickup in older TACHTROL 2 installations, with the T77220-1-201 and 70087-3040-020 identifiers for this assembly. The -020 variant belongs to the 70087-3040 pickup family, a common Airpax sensor subset used with tachometer modules in industrial equipment. Airpax’s TACHTROL 2 product line historically supported tachometer inputs from rotating machinery across a frequency range appropriate for industrial speeds, with published references indicating a tach input range from about 0.1 Hz up to around 1 kHz. The TACHTROL 2 system has been documented as discontinued by the manufacturer, but replacement pickups and compatible spare parts remain listed by third-party distributors, including platforms that catalog T77220-1-201 variants. Typical applications include speed monitoring on motors, conveyors, pumps, fans, and other industrial equipment where the TACHTROL 2 tachometer provides process-control feedback. When ordering, verify that the -201\/-020 pairing matches your specific TACHTROL 2 installation and that the 70087-3040-020 is compatible with your control wiring and connector configuration.\u003c\/p\u003e\u003c\/div\u003e","brand":"AIRPAX","offers":[{"title":"New","offer_id":51657152332078,"sku":null,"price":435.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_855eaf64-11b5-4f96-8eb8-12752fe160de.jpg?v=1769466448","url":"https:\/\/plgautomation.com\/products\/airpax-t77220-1-201-w-70087-3040-020-tachtrol-tachometer-pickup","provider":"PLG Automation ","version":"1.0","type":"link"}
