Mechanical Cam Switches

BNS mechanical single position limit switches

Counter with rugged 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 switched in a separate sealed chamber. The optimal choice of the plunger shape in combination with our cams is decided by the application requirements. This guarantees a long service life for your application.

Features

  • Long service life
  • Robust housing for extreme applications
  • Three model series
  • Optional: Function indicator
  • Dual chamber system with IP67 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

BNS mechanical multiple position switches

Counter with rugged housing for extreme applications

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

Features

  • Long service life
  • Robust housing for extreme applications
  • IO-Link adaptable
  • Six model series
  • Depending on the model series, up to 16 interfaces
  • Function indicator, optional

BNS mechanical single position limit switches with safety switch positions

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 function in accordance with DIN EN 60204-1/VDE 0113 and DIN EN 60947-5-1

BNS 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. 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
  • Freely selectable number of safety switch positions in one multiple position switch
  • Safety switch positions can be combined with standard switching elements

BNS 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
  • Dual chamber system with IP67 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

BES inductive single position limit switches

Non-contacting and thus free from wear during operation

Our inductive single position limit switches combine the advantages of an inductive sensor with those of our mechanical housing-based line of products by carrying over their robust housings and using a reliable inductive switching element for the switching function. As a result, you benefit from compact configurations and high switching distances, which enable non-contacting and thus wear-free operation. And 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 design
  • Mechanical housing normed to the fixing mass can be used
  • Long switching distances
  • Contact-free and therefore wear-free
  • IP67: Resistant to aggressive cooling lubricants

BNS inductive multiple position switches

Working without making contact and close to each other

Our inductive multiple position limit switches combine the advantages of an inductive sensor with those of our mechanical housing-based line of products. By carrying over their robust housings and using a reliable inductive switching element for the switching function. As a result, you benefit from compact configurations and high switching distances, which enable non-contacting and thus wear-free operation. The coordinated transmission frequencies of the inductive switching elements allow for a tight sequential arrangement. And 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 display for each switching point
  • Compact design
  • Mechanical housing normed to the fixing mass can be used
  • Long switching distances
  • Contact-free and therefore wear-free
  • Tight sequential arrangement possible by coordinated transmission of switching frequencies
  • IP67: Resistant to aggressive cooling lubricants

BNS mechanical multiple position limit switches with interchangeable plunger unit

Interchangeable unit for quick and easy plunger replacement

Our mechanical multiple position limit switch with interchangeable unit are available for standard applications as well as with safety switch positions for increased requirements. With them, the entire switch does not have to be removed to replace individual plungers. Loosening of two screws is enough to remove the plunger unit. This saves you time and money.

Features

  • Short service times thanks to simple replacement of the interchangeable unit
  • Fast exchange of individual ram or the entire unit directly on the machine
  • Low repair costs
  • No wiring errors
  • Depending on the model series, up to six switch positions
  • Two model series
