Description

The SMC SA/SAM-DA-400-07B-P4N-F is a high-performance rodless pneumatic cylinder from SMC Corporation’s widely recognized SAM series, engineered to deliver precise, reliable linear motion in space-constrained industrial automation applications. As a double-acting, guided actuator with an integrated carriage and built-in magnetic proximity switches, the SMC SA/SAM-DA-400-07B-P4N-F eliminates the need for external guides or support structures, significantly reducing system footprint while maintaining high rigidity and load-carrying capacity. With a 400 mm stroke length and bore size of 7 mm (indicated by “07B”), this compact unit is ideal for pick-and-place, part transfer, clamping, and indexing tasks in packaging, electronics assembly, and machine tool automation.

Designed for durability and ease of integration, the SMC SA/SAM-DA-400-07B-P4N-F features a sealed body construction rated to IP65, protecting internal components from dust, coolant, and light washdown—making it suitable for demanding production environments. The “P4N-F” suffix denotes factory-installed auto switches (reed or solid-state, depending on configuration), a non-lube design (maintenance-free operation), and front-side mounting orientation. Unlike traditional rod-type cylinders that require additional linear bearings, the SMC SA/SAM-DA-400-07B-P4N-F uses internal precision linear guides to prevent rotation and support moment loads, enabling direct mounting of tooling onto the moving carriage. This integrated approach not only simplifies mechanical design but also enhances repeatability and long-term reliability across millions of cycles.

Main Features and Advantages

Space-efficient guided motion in a single package: The defining advantage of the SMC SA/SAM-DA-400-07B-P4N-F is its ability to combine actuation and guidance in one compact extruded body. By eliminating external rails or rods, it reduces machine footprint by up to 50% compared to conventional solutions—critical in modern high-density automation cells. The internal linear ball bushings provide smooth, low-friction movement while resisting radial and moment loads, ensuring stable tooling alignment even during high-speed cycling.

Maintenance-free operation with long service life: Thanks to its non-lube design and sealed structure, the SMC SA/SAM-DA-400-07B-P4N-F operates reliably without requiring oil mist lubrication—a significant benefit in cleanroom, food processing, or electronics manufacturing where oil contamination is unacceptable. The wear-resistant sealing system and hardened guide surfaces enable over 10 million cycles under typical conditions, minimizing unplanned downtime and total cost of ownership.

Integrated position feedback for seamless control: The “P4N” designation confirms that the SMC SA/SAM-DA-400-07B-P4N-F ships with two pre-installed magnetic proximity switches (typically solid-state for long life), wired to a standard M8 connector. These provide real-time end-of-stroke confirmation to PLCs or controllers, enabling synchronized sequencing without external sensors. The switches are easily adjustable along the slot, allowing flexible positioning for mid-stroke detection if needed.

Robust environmental protection for harsh settings: With an IP65 rating, the SMC SA/SAM-DA-400-07B-P4N-F withstands airborne particulates, splashing water, and light cleaning sprays—common in automotive, metalworking, and bottling lines. The anodized aluminum body resists corrosion, while the stainless steel fasteners enhance durability. This resilience ensures consistent performance in environments where lesser actuators would degrade or fail prematurely.

Application Field

The SMC SA/SAM-DA-400-07B-P4N-F excels in applications demanding precise, repeatable linear motion within tight spatial constraints. In packaging machinery, it drives carton erectors, label applicators, and case sealers—where its 400 mm stroke accommodates standard box sizes and its built-in switches confirm cycle completion for downstream coordination. The non-lube design is especially valuable in food and pharmaceutical packaging, where compliance with hygiene standards (e.g., FDA, EHEDG) prohibits oil-based systems.

In electronics and semiconductor assembly, the SMC SA/SAM-DA-400-07B-P4N-F handles delicate component transfer between stations. Its low vibration, high repeatability (±0.1 mm), and clean operation prevent misalignment or damage to micro-parts. Similarly, in automotive component manufacturing, it powers clamping fixtures for welding or machining cells, where its moment load capacity resists torque from off-center forces.

Material handling systems also benefit from the SMC SA/SAM-DA-400-07B-P4N-F, particularly in gantry loaders, palletizers, and sorting conveyors. Its ability to carry moderate payloads over a half-meter range—without external support—simplifies mechanical design and reduces maintenance points. For retrofit projects, replacing bulky rod cylinders with the SMC SA/SAM-DA-400-07B-P4N-F often enables faster cycle times and smaller machine footprints, directly improving throughput and floor-space utilization.

Installation and Maintenance

Pre-installation preparation: Before mounting the SMC SA/SAM-DA-400-07B-P4N-F, ensure the mounting surface is flat and rigid to prevent stress on the extruded body. Use the specified M4 or M5 bolts (per SMC documentation) and torque to recommended values to avoid distortion. Connect clean, dry, filtered air (≤40 µm filtration) at 0.5–0.6 MPa for optimal performance. Route the M8 switch cable away from high-voltage lines to prevent signal interference. Verify that the carriage can move freely through its full 400 mm stroke without obstruction before pressurizing.

Maintenance recommendations: Although the SMC SA/SAM-DA-400-07B-P4N-F is designed for maintenance-free operation, periodic inspection is advised in high-cycle or contaminated environments. Check the sealing strip along the slot for tears or debris buildup, as foreign material can accelerate wear or cause leakage. If operating near the speed or load limits, monitor for increased noise or reduced repeatability—early signs of guide wear. The built-in switches typically outlast the cylinder; however, if signal loss occurs, test with a multimeter before replacing. Store spare SMC SA/SAM-DA-400-07B-P4N-F units horizontally in dry conditions to prevent seal deformation.
