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

In mechanical multiple 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
• IO-Link adaptable
• Six model series
• Up to 16 interfaces, depending on the model series
• Function indicator optional
• Two-chamber system with IP67 degree of protection: wear-free membrane with hermetic separation of the plunger mechanism and the switch interior

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. Balluff safety switches are 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

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. The number of safety switch positions in a single multiple position switch is arbitrary and can also be combined with standard switching elements. Balluff safety switches are 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
• Four model series
• Up to 16 switch positions, depending on the model series
• A freely selectable number of safety switch positions in one multiple position switch
• Safety switch positions can be combined with standard switching elements

With mechanical single position limit switches in smaller configurations, safety switching elements are not feasible. 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

Our inductive single position limit switches combine the advantages of an inductive sensor with those of our mechanical housing-based line of products. The advantages received include their robust housings and a reliable inductive switching element for the switching function. As a result, you benefit from compact configurations and high switching distances. This enables non-contacting and, therefore, wear-free operation. Since the switching elements are equipped with LEDs, you can immediately recognize each switching function on the housing cover.

Features

• Reliable inductive active principle
• Function indicator with LEDs
• Compact configuration
• Mechanical housing normed to the fixing mass can be used
• Long switching distance
• Non-contacting and thus free from wear
• IP67 degree of protection: Resistant to aggressive cooling lubricants

The advantages received include their robust housings and a reliable inductive switching element for the switching function. As a result, you benefit from compact configurations and high switching distances. This enables non-contacting and, therefore, wear-free operation.

The coordinated transmission frequencies of the inductive switching elements allow for a tight sequential arrangement. Since the switching elements are equipped with LEDs, you can immediately recognize each switching function on the housing cover.

Features

• Reliable inductive active principle LED function indicator for each switch position
• Compact configuration
• Mechanical housing normed to the fixing mass is useable
• Long switching distance
• Non-contacting, and so free from wear
• Tight sequential arrangement possible by coordinated transmission of switching frequencies
• IP67 degree of protection: resistant to aggressive cooling lubricants

Our mechanical multiple position limit switch with interchangeable plunger unit are available for standard applications. Safety switch options are also available for increased requirements. With them, the entire switch does not have to be removed to replace individual plungers. Simply loosen two screws to remove the plunger unit. This efficiency saves you time and money.

Features

• Short service times thanks to simple assembly of the interchangeable unit
• Fast exchange of individual plunger or the entire unit directly on the machine
• Low repair costs
• No wiring errors
• Available with up to 6 switch positions, depending on the model series
• Two model series

Equipped with a special switching element and a sophisticated plunger design, the mechanical position limit switches are perfect for extended temperature ranges. They are suitable for operating temperatures of up to 180 °C. Ideal for harsh environments in mold making in the plastics industries, steel, and iron works.
