For positioning and limit switch tasks

Position and row-position counters are classics in the metal-working industry and world-wide automotive production. They have proven their worth in automation for decades.

Mechanical sensors are used for positioning and limit switch tasks on machine tools and presses, flexible production centres, robots, assembly and conveying equipment, and in machine and plant construction. For decades, they have proven their worth as the traditional strongmen of automation.

Product families

  • Mechanical single position limit switches

    Switch with robust housing for extreme applications

    In mechanical single position limit switches without positive opening, a telescoping plunger executes the switching process. With its help, a mechanical switching element is connected in a separate, sealed chamber. The optimal choice of the plunger shape in combination with our cams is decisive in individual cases. This guarantees a long service life for your application.

    Features

    • Long service life
    • Robust housing for extreme applications
    • Three model series
    • Optional: Function indicator
    • Two-chamber system with IP67 degree of protection: Wear-free membrane with hermetic separation of the plunger mechanism and the switch interior
    • Maintenance-free, self-lubricating ram guide with plain bearing bush
    Single position limit switches
  • Mechanical multiple position limit switches

    Switch with robust housing for extreme applications

    In mechanical multiple position limit switches without positive opening, a telescoping plunger executes the switching process.

    Reliable forcible opening even with welded contacts

    Do you value reliable switching even with welded contacts? Then equip your safety functions such as emergency stops or limit stops with Balluff safety switches. Their switching process is triggered by a rigid plunger that actuates a mechanical switching element with forcible opening. If this plunger moves, it breaks the contact. Your reliable, safe choice.

    Features

    • Also suitable for welded contacts
    • Safety functions in accordance with DIN EN 60204-1/VDE 0113 and DIN EN 60947-5-1
    Single position limit switches with safety switch positions
  • Mechanical multiple position limit switches with safety switch positions

    Reliable forcible opening even with welded contacts

    Do you value reliable and safe switching even with welded contacts? Then equip your safety functions such as emergency stops or limit stops with Balluff safety switches. Their switching process is triggered by a rigid plunger that actuates a mechanical switching element with forcible opening. However, if this plunger moves, it breaks the contact. Good to know: The number of safety switch positions in a single multiple position switch is arbitrary and can also be combined with standard switching elements.

    Features

    • Also suitable for welded contacts
    • Safety functions in accordance with DIN EN 60204-1/VDE 0113 and DIN EN 60947-5-1
    • Four model series
    • Depending on the model series, up to 16 switch positions
    • A freely selectable number of safety switch positions in one multiple position switch
    • Safety switch positions can be combined with standard switching elements
    Multiple position limit switches with safety switch positions
  • Mechanical single position limit switches with positive opening

    Secured switching even with welded contacts

    Safety switching elements are not feasible due to the design, especially with mechanical single position limit switches in smaller configurations. In contrast, solutions with positive opening already exist. In these, the switching process is triggered by a rigid plunger that actuates a mechanical switching element with forcible opening. However, should this plunger move, it breaks the contact. This means that you have reliable control of switching processes even with welded contacts.

    Features

    • Also suitable for welded contacts
    • Two model series
    • Two-chamber system with IP67 degree of protection: Wear-free membrane with hermetic separation of the plunger mechanism and the switch interior
    • Maintenance-free, self-lubricating ram guide with plain bearing bush
    • Rigid plunger
    Single position limit switches with positive opening
  • Mechanical multiple position limit switches with positive opening
