Pneumatic Cylinder and Solenoid Actuator for Rejection Gates

Product Specifications

Technical details and manufacturing context for Actuator (Pneumatic Cylinder/Solenoid)

Definition

This actuator, available as a pneumatic cylinder or solenoid, serves as the power source for a rejection gate or mechanism in industrial automation systems. It converts compressed air energy (pneumatic) or electrical energy (solenoid) into linear or rotary motion to physically move the gate or mechanism that rejects defective products or materials from a production line. The actuator is a component designed for integration into sorting, inspection, or packaging machinery where precise and repeatable rejection actions are required. Typical applications include diverting faulty items, removing off-spec parts, or triggering a reject mechanism in a conveyor system. The unit operates based on signals from sensors or control systems, providing controlled mechanical force to actuate the rejection mechanism. Key specifications include an operating pressure range of 1.0–1.6 MPa, a bore size of 32–125 mm (ISO 6432), and a stroke length of 25–300 mm (ISO 6431). The operating temperature range is -5 to 60 °C. For solenoid versions, the supply voltage is 24 V DC ±10% (IEC 60038) with a power consumption of 2.5–8 W. The IP rating is IP54–IP65 (IEC 60529). Materials include aluminum alloy (6061-T6, anodized), stainless steel, brass, and engineering plastics. Seals are made of NBR (nitrile rubber, oil resistant). Weight ranges from 1.5 to 8.5 kg depending on bore and stroke. Response time is 0.05–0.2 seconds at full stroke and rated pressure. These values are directory reference ranges and must be verified for the specific model and application with the legal manufacturer or supplier. The actuator is not a standalone product; it requires integration with a control system and appropriate air or electrical supply. Always confirm model-specific parameters and standards compliance before procurement.

Working Principle

Pneumatic cylinders use compressed air to move a piston within a cylinder, creating linear motion. Solenoids use electromagnetic force to move a plunger when energized. Both types provide controlled mechanical force to operate rejection mechanisms based on signals from sensors or control systems. The actuator converts energy into mechanical motion, which is transmitted to the rejection gate or mechanism. The force and speed are determined by the operating pressure, bore size, and stroke length. For pneumatic types, the air supply must be regulated within the specified pressure range. For solenoid types, the electrical supply must match the voltage and power requirements. The actuator's response time is critical for high-speed rejection applications. Proper installation and alignment are necessary to ensure reliable operation. The actuator is designed for industrial environments and must be selected based on the required force, stroke, and cycle rate.
