MICRO SWITCH Miniature Industrial Limit Switch 002389 SZL-VL-S Series Issue 3 Datasheet FEATURES Approvals: CCC, CE, cULus Sealed to IP67, NEMA 1, 12, 13 Snap-action contacts Die-cast metal housing with glass-filled, flame-retardant thermoplastic cover Stainless steel levers with either steel and nylon rollers Variety of actuators Positive-opening contacts (side rotary version only) RoHS compliant Utilization category: AC-15 A300 (380 Vac/0.5 A) DC-13 Q300 (220 Vdc/0.05 A) Mechanical life rating: 10 million cycles Electrical life rating: 0.5 million cycles DESCRIPTION APPLICATIONS The SZL-VL-S Series miniature-type limit switch is designed for Scissor/boom position detection use in applications where limited mounting space is available. Vehicle accessibility lifts With IP67 seal rating, these switches are suitable for OEM Escalators/Motorized walkways machinery that requires a rugged and reliable limit switch Machine tools capable of being mounted in space restricted applications. Its Mobile light towers design enhances ease of wiring with ample wiring space, and Packaging equipment has an optional cable gland for faster and more efficient wiring Conveyor equipment termination. Overhead doors The SZL-VL-S Series switches have a split-housing design Agriculture equipment made of a die-cast body and head with glass-filled, flame- Rail passenger cars (internal doors) retardant thermoplastic cover. The cover is removable for easy access and ease of installation. Modular actuator head design PORTFOLIO allows for configurations to meet a variety of application The MICRO SWITCH SZL-VL-S series joins Honeywells NGC needs. The SZL-VL-S are available globally and carry Series and the GLL Series switches for general industrial certifications for applications around the world. applications. The combined portfolio helps ensure a variety of industrial applications or position sensing tasks can be DIFFERENTIATION performed by a Honeywell limit switch.

IP67 indicates that the SZL-VL-S is protected against the effect of immersion in water between 15 cm and 1 m. The competition standard is IP65 which can only withstand low pressure spray and jets of water. The electrical rating of 10 A permits the SZL-VL-S switch to be used with heavier electrical loads than competitors VALUE TO CUSTOMERS These switches are user-friendly interfaces and may be used in a broad range of applications to help meet the challenges of many industrial environments. A variety of actuators fit on the same platform reducing the need to use various kinds of mounting hardware.
