It features a single-pole double-throw (SPDT) contact configuration in a normally closed (NC) arrangement, actuated by a roller plunger mounted on the side of the zinc body. The switch is rated for 600 volts AC and carries an IP20 ingress protection rating. It mounts via a side bracket and terminates with screw-type connections. Licensed electricians and industrial maintenance technicians install this switch to detect machine component position, end-of-travel, or object presence in control circuits.\u003c\/p\u003e\n\u003cp\u003eThis limit switch suits residential and light commercial applications within NEMA 1 environments — dry, indoor locations free from unusual dust, moisture, or corrosive conditions. It is commonly installed on conveyor systems, door assemblies, gate controls, and general-purpose machine guarding circuits where reliable position feedback is required. The roller plunger actuator makes it well suited for cam-driven or side-approach actuation scenarios where a rotating or sliding mechanical element trips the switch.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSPDT normally closed contact form for fail-safe position sensing\u003c\/li\u003e\n  \u003cli\u003eRoller plunger actuator with side-mount orientation for cam or lateral approach applications\u003c\/li\u003e\n  \u003cli\u003e600-volt AC rating supports a wide range of industrial control voltages\u003c\/li\u003e\n  \u003cli\u003eZinc body construction for durability in light industrial environments\u003c\/li\u003e\n  \u003cli\u003eScrew terminal connections for secure, tool-accessible wiring\u003c\/li\u003e\n  \u003cli\u003eRoHS compliant and tested to IEC 60529 standards\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-install general purpose limit switch for NEMA 1 rated industrial control and position-sensing circuits.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified electrician in accordance with applicable NEC requirements and local codes. De-energize and lock out the control circuit before mounting or wiring the switch. Secure the bracket mount firmly to prevent actuator misalignment during operation. Verify actuator travel and overtravel clearances against the mechanical assembly before restoring power.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Form\u003c\/strong\u003e: SPDT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Configuration\u003c\/strong\u003e: NC (Normally Closed)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVoltage Rating\u003c\/strong\u003e: 600 volts AC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActuator Type\u003c\/strong\u003e: Roller Plunger\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActuator Location\u003c\/strong\u003e: Side\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTerminal Type\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMount Type\u003c\/strong\u003e: Side Bracket\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNEMA Rating\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIngress Protection Rating\u003c\/strong\u003e: IP20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 0.95 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Depth\u003c\/strong\u003e: 2.44 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActuator Length\u003c\/strong\u003e: 2.44 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Operating Temperature\u003c\/strong\u003e: -20 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Operating Temperature\u003c\/strong\u003e: 185 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Zinc\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.17 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: IEC 60529, RoHS Compliant\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SQUARE D\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9007AB21\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SCHNEIDER ELECTRIC","offers":[{"title":"Default Title","offer_id":51542309470514,"sku":"9007AB21","price":74.19,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1d6a875319dac471992d5138ecfc5d6d.jpg?v=1785897684","url":"https:\/\/voomisupply.com\/products\/square-d-9007ab21-limit-switch-spdt-nc-roller-plunger","provider":"Voomi Supply","version":"1.0","type":"link"}
