Solenoid Coil & Plunger

Product Specifications

Technical details and manufacturing context for Solenoid Coil & Plunger

Definition

The solenoid coil and plunger is a core component in solenoid-based drive mechanisms. It consists of a wire-wound coil, typically made of copper or aluminum, and a movable plunger made of low-carbon electrical steel. When electrical current flows through the coil, it generates a magnetic field that magnetizes the plunger, attracting it into the center of the coil and producing linear displacement. This assembly is fundamental to solenoid valves, actuators, and other electromechanical systems requiring controlled movement. The coil is insulated with materials rated for temperature classes F to H per IEC 60085, and the assembly is available with IP ratings from IP54 to IP65 per IEC 60529 for dust and water protection. Key parameters include coil resistance (12–120 Ω), operating voltage (12–240 V AC/DC), power consumption (5–50 W), stroke length (5–50 mm), pull force (10–200 N), response time (10–100 ms), operating temperature (-40 to 85 °C), and weight (0.1–2.5 kg). The plunger material is typically low-carbon steel grades C1008–C1010 per ASTM A576. These values are directory reference ranges and must be confirmed for the specific model and application with the legal manufacturer or supplier. The assembly is designed for precise linear motion in industrial equipment, and selection requires consideration of voltage, duty cycle, force, stroke, and environmental conditions. Verification of model-specific values and standards is essential before procurement.

Working Principle

When electrical current flows through the coil, it creates a magnetic field that magnetizes the plunger, which is made of ferromagnetic material. The magnetic attraction force pulls the plunger into the center of the coil, creating linear motion. When de-energized, a spring or other return mechanism typically returns the plunger to its original position. The magnitude of the force and stroke depends on the coil design, current, and plunger geometry. The response time is the time to reach 90% of full stroke, typically 10–100 ms. The assembly operates within a temperature range of -40 to 85 °C, with derating above 85 °C. The coil resistance and operating voltage determine current draw and heat generation, and continuous duty may require derating. The plunger material is low-carbon steel for magnetic properties, and the coil wire material can be copper or aluminum, with copper offering higher conductivity and aluminum offering cost savings.
