Pneumatic cylinder switches are integral components in the control systems of pneumatic machinery. These systems rely on highly compressed air to generate motion in mechanical devices. One commonly used type of switch is the reed switch, which operates by responding to a magnetic field — opening or closing its contact when a magnet is either present or removed.
What Are Pneumatic Cylinder Switches Used For?
Despite the variety of pneumatic cylinder switches available, they all serve a shared purpose: enabling the integration of pneumatic cylinders into automated systems. These switches monitor the cylinder's position and transmit signals to the control unit, ensuring precise and responsive automation.
Types of Pneumatic Cylinder Switches
A wide range of pneumatic cylinder switch types exist, including actuators, pneumatic relays, solid-state switches, and reed switches. Certain models also feature built-in LED indicators for easy status monitoring. Key factors such as maximum operating temperature, voltage rating, and allowable voltage drop vary by switch type, so selecting the right one depends on the specific operational demands of your system.
The SMC pre-wired connector auto switches are available in 3 or 4 pin 8mm style, or 4 pin 12mm style. 3 standard wire lengths are also available: 0.5m (S), 1.0m (M) and 3.0m (L). With the use of the pre-wired connector switch, the need for minimum order quantities for "special" auto switches with connectors is eliminated, and wiring with the use of standard connectors is simplified.
Eliminates harnessing work by cable with connector specifications
Adopts global standardized connector (IEC947-5-2)
IP67 construction
