Precision switching with unmatched durability
Single and multiple position cam switches are used as actuators for automatic controls, for positioning, end-of-travel, transfer lines, transport equipment, and in machine and equipment building. Balluff single and multiple position switches have been proven for decades under harsh conditions. They ensure trouble-free function under conditions of vibration, shock, rapid temperature fluctuations, aggressive coolants, and heavy presence of chips.
Highly elastic, wear-free membrane made of Viton is used for hermetic sealing between the plunger mechanism and switch chamber. This dual chamber design ensures an IP 67 rating. Snap and creep switch elements are available as changeover contacts with self-cleaning effect. A variety of switch elements can be used.
Mechanical switches consist of two primary components. First a rugged single or multiple position switch assembly with a wide variety of switch elements. Secondly linear or rotary cams and associated cam trays or drums.
Balluff's inductive mechanical switches in the 602 and 610 series housings are available with extended range for use in robot and gantry applications. Complementary electronic switching elements allow the sensor to be used either as normally open or normally closed.
The tuned sensing coil oscillator frequencies of the inductive sensors allow them to be installed very close to each other. Mutual interference is precluded at 12 mm spacing and 4 mm switching distance. The inductive elements are compatible with pulsed power supplies. Monitoring must be implemented with a safety PLC or with a safety relay.
Balluff inductive single and multiple position mechanical switches combine the advantages of an inductive sensor with those of our mechanical housing-based line of products. While we use the same robust housings as for the mechanical version, a reliable inductive switching element provides the switching function.
A metallic cam is sensed by an inductive sensor element, which changes state electronically to activate the output signal. Non-contact operation for wear-free service in areas without metallic chips. Output function LEDs are standard on inductive switch assemblies.
Balluff single and multiple position cam switches are used as actuators for automatic controls, positioning, end-of-travel, machine tools, transfer lines, transport equipment, automobile industry, and in machine and equipment building. Their proven design principle and large number of possible switching operations ensure lasting quality and reliability.
The switching operation is performed using a telescoping plunger. This plunger is used to switch a mechanical switching element in a separate, sealed chamber. Optimum selection of the plunger style in combination with our cams guarantees long service life.
Balluff offers the ability to customize the mechanical switches to meet the needs of applications where a standard switch will not fulfill those requirements.
Custom products include mixed assemblies combining snap, safety, and inductive elements, pre-wired and factory tested micro or mini style connectors. Custom configurations receive unique part numbers with documentation.
Balluff's mechanical switches with positive break switch elements coupled with high switching element density, rugged construction, and long life expectancy, combine to prove a perfect match for safe and reliable human-robot interface. The switching operation is initiated by a rigid plunger which actuates a mechanical switching element with positive-opening contacts per DIN EN 60204-1/VDE 0113.
Balluff's high-temperature mechanical switches the optimal solution for harsh environments in mold making, plastic industry and in the steel industry. These switches are available in the miniature 99 single position and 40/46 multiple position housings.
Balluff multiple position switches have for decades proven themselves under the most difficult conditions. The design principle and large number of possible switching types and configurations ensure the highest level of quality and reliability. The plungers are the only moving parts outside of the housing and are subjected to daily exposure to a wide range of unavoidable influences.
For such applications Balluff offers the Series 61 and 100 switch family with quick-change plunger block as an option to the standard multiple limit switches. The Balluff multiple position limit switch with quick-change plunger block makes time-consuming plunger replacement a thing of the past. In just a few moments the complete block system can be replaced without the use of special tools and without the risk of wiring mistakes.
Balluff's miniature single, 99/100 series, and multiple position, 40/46 series, mechanical switches offer the smallest plunger spacing. These switches are used for E-Stop and end-of-travel applications and utilize positive-opening contacts.
The switches have rigid plungers that will force open the switch element. Balluff's mechanical switches have a dual-chamber system with IP 67 protection: wear-free membrane with hermetic sealing from plunger mechanism and switch chamber. Self-lubricating plunger guide with slide bearing provides a maintenance free switch.
