The SZL-VL-S Series miniature-type limit switch is designed for use in applications where limited mounting space is available. With IP67 seal rating, these switches are suitable for OEM machinery that requires a rugged and reliable limit switch capable of being mounted in space restricted applications. Its design enhances ease of wiring with ample wiring space, and has an optional cable gland for faster and more efficient wiring termination.
The SZL-VL-S Series switches have a split-housing design made of a die-cast body and head with glass-filled, flameretardant thermoplastic cover. The cover is removable for easy access and ease of installation. Modular actuator head design allows for configurations to meet a variety of application needs. The SZL-VL-S are available globally and carry certifications for applications around the world.

DIFFERENTIATION：
• With robust environmental ratings, the SZL-VL-S is protected for all kinds of industrial applications. 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.
