Pneumatic Timers

Festo Pneumatic Timers

Festo pneumatic timers are specialized control elements used to delay signals within pneumatic systems. They offer highly stable timing performance, simple configuration, and robust construction—making them essential for applications requiring timed actuation, signal sequencing, soft start operations, and controlled motion transitions.

These timers feature adjustable delay ranges, compact form factors, and compatibility with a wide range of Festo pneumatic components, ensuring seamless integration into existing circuits.

⭐ Important: Pneumatic timers enable precise delay control without the need for electrical components, making them ideal for purely pneumatic or ATEX-sensitive environments.

Design & Functionality

Pneumatic timers operate by storing and releasing compressed air at a controlled rate to create a delay before switching the output signal. The timing is adjusted using an integrated restrictor or needle mechanism, allowing users to fine-tune delay periods with consistency.

Available timer functions include:
• On-delay timers (signal output is delayed after input activation)
• Off-delay timers (signal disappears after a delayed time)
• Impulse timers (short output pulse)
• Signal extension timers

The design ensures stable timing accuracy, low hysteresis, and long-term repeatability.

⭐ Important: Adjustable timing control enables precise sequencing of actuators, valves, and machine events.

Total Crossed Beams

(Translated to: Functional coverage across timer types)

The product family covers full timing needs for pneumatic automation—from basic signal delays to complex sequence control.

Ensures reliable function regardless of circuit layout, actuator type, or operating pressure.

Designed to maintain timing consistency even under varying load and pressure conditions.

Beam Pitch Options

(Translated to: timing ranges, flow capacities, adjustment variants)

Wide range of timing intervals, typically from fractions of a second up to several minutes, depending on the model.

Optional configuration features include:
• Fine needle-adjustable timing
• Integrated non-return flow restrictor
• Panel-mounting variants
• Manual override options
• Versions with precise micro-flow channels for long delays

These options allow the pneumatic timer to be optimized for slow responses, rapid switching, smooth actuator transitions, or strict timing accuracy.

⭐ Important: Broad timing range adaptability ensures ideal performance for filling, clamping, indexing, and process synchronization tasks.

Intrinsic Synchronism

Internal air chambers and throttling mechanisms ensure synchronized timing sequences with minimal fluctuation.

Optional features such as damping chambers or micro-restrictor elements help maintain consistent time delays independent of supply pressure fluctuations.

Ensures stable and predictable timing performance—critical for machine repeatability and coordinated actuator motion.
