    Our ideas on compact Limit Switches.Easy to use and highly functional, proven byour long years of market results."Actuators that can be used for detection," "long life and high reliability,""highly accurate detection," "able to bear heavy loads," "easy installation and

    maintenance......"The essence of Limit Switches.

    Matsushita Electric Works, Ltd. values this essence. Unique contact switching func-tions. A body that makes wiring easy. Able to handle low-level loads linked to PCs,the core of the FA era. Also, switching capacity with room to control heavy loadsdirectly. These Limit Switches are not only compact and lightweight, but also theypossess electronic responsiveness, contact reliability, long life, maintainability,economic value, and sensitivity, based on market needs.

    HL Limit Switches

    High-capacity Limit Switches with excellent envi-ronment-proofing with a plentiful array of types,including connector type, low-level load model,and economic thermoplastic enclosure. The low-level load model has a highly reliable twin cross-bar contact. Awarded the 1994 prize.

    ML mini Limit Switches

    Compact and lightweight, but mechanicallyhighly sturdy. Also comes as a series withlamps and as a terminal mold model type.

    Compact vertical type Limit Switches

    VL mini Limit Switches

    Uses Au-clad contact that can handlelow-level loads with little chattering andbouncing. The series includes with LEDlamp, with neon lamp, and touch switch.

    DL mini Limit Switches

    The contact can be forced open due to theforced contact opening mechanism, even in theunlikely event of a welded contact. Awarded the1989 prize. Conforms to DIN standards.

    IP64 IP67

    Vertical type Limit Switches

    A standards approved limit switch (standardmodel.) The type with lamp comes as bothAC type (neon lamp) and DC type (LEDlamp.)

    IP67IndustrieForumDesignHannover

    Suited to a wide variety of applications due toa broad array of actuators

    Operation can be checked at a glance with theattached lamp

    Protective construction is expressed in IEC equivalents. Refer to each product guide for details.

    High contact reliability

    The load operation status canbe checked easily at aglance. With both LED lamptype and neon lamp type,which can be connecteddirectly to the load.

    A high-level seal that satisfies IEC IP67

    HL Limit Switches are com-pact and highly reliable withexcellent environment-proofcapabilities.

    DL limit switch area contactscan be forced open, even ifthe contact is welded.

    Easy wiring and installationThe terminal area of VL LimitSwitches are fully open,making wiring easy.

    With the use of our unique contacts and mecha-nism, we achieved a superior contact reliability andweld resistance, as well as a longer usable life.
