Z-15GQ21-B

Description

Product DescriptionEnsure precision mechanical execution and heavy-duty reliability in your industrial automation systems with the Premium Z-15GQ21-B Panel-Mount Cross Roller Plunger Basic Switch. Engineered as a high-performance, general-purpose micro limit switch, this component features a hardened cross roller plunger actuator oriented at a $90^circ$ angle to the switch body. This unique design is specifically optimized to convert sequential, linear cam tracking or sliding mechanical movements into crisp, rapid electrical signals.Housed in a rugged, heat-resistant thermosetting phenolic resin shell, the switch provides exceptional structural rigidity, high insulation safety, and resistance to heavy mechanical shock. The underside features a standardized SPDT (Single Pole Double Throw: 1NO + 1NC) three-point terminal block utilizing heavy-duty M4 screw connections, capable of handling robust high-current power breaking up to 15A.Key FeaturesCross Roller Plunger Actuator: The parallel $90^circ$ roller wheel design minimizes friction during lateral, sliding cam movements, ensuring smoother mechanical travel and a precise trip point.Snap-Action SPDT Contacts: High-conductivity silver contacts rapidly execute state transitions ($0.5text{mm}$ contact gap), preventing electrical arcing and signaling delays.Panel-Mount Threaded Bushing: Features a robust brass threaded neck with locking hex nuts and washers for secure, flush installation through control panel frames or machine brackets.15A High-Load Capacity: Rated to safely manage demanding electrical loops up to 250V AC (15A) or 30V DC (6A) without premature contact degradation.Vibration-Proof Screw Terminals: Standardized three-M4-screw layout (COM, NO, NC) guarantees a secure, high-conductivity connection in vibration-heavy environments.## Technical SpecificationsParameterSpecificationModel BlueprintZ-15GQ21-B / XZ-15GQ21-BActuator TypePanel-Mount Cross Roller Plunger ($90^circ$ Orientation)Contact ConfigurationSPDT (1NO + 1NC)Action TypeMomentary / Snap ActionCurrent/Voltage Rating15A at 125V/250V AC | 6A at 30V DCTerminal Type3-M4 Screw TerminalsContact Gap0.5mm (Standard Medium Operating Force)## Compatibility & Application GuideThis classic panel-mount micro-switch footprint is highly standardized across global automation lines, serving as a reliable drop-in replacement part for modern machinery and heavy equipment.Common Industrial UsesElevator & Lift Systems: Frequently deployed as a precise elevator door interlock, car positioning sensor, or threshold limit switch.CNC Machinery & Routers: Functions as an axis end-stop or safety over-travel limit switch on automated industrial mills, plasma tables, and heavy-duty 3D printers.Conveyors & Material Handling: Ideal for detecting sliding gates, tracking passing pallets, or positioning pneumatic cylinder arms along assembly lines.Boilers & Industrial Doors: Used as a heavy-duty door contactor or position sensor in commercial wood-log boilers, blast ovens, and security shutters.Brand InterchangeabilityThis part features standard mounting holes and functions as a direct structural replacement for identical product configurations across platforms like DigiKey, including:Omron Automation: An exact factory-spec replacement for the premium Omron Z-15GQ21-B industrial series.Daier Electron & Shuyi: Directly swaps out with DAIER Z-15GQ21-B and matching SYZ-15GQ21-B panel micro-switches.Universal Cross-References: Fits identical dimensional footprints from Uxcell, Xurui (XZ-15GQ21-B), CNC Electric, Suns, and BAW Electric.⚠️ Installation Note: Disconnect all live electrical loops before installing. When mounting onto panels, verify that the directional travel of your cam aligns perfectly with the roller wheel axis ($90^circ$ cross-plunge motion). Striking the plunger against the wheel’s side profile can bend the threaded bushing housing and cause the internal contacts to seize.
