Technical Specifications Supply voltage: 24 V DC ±10%; control input: 4–20 mA; output force: 50 lbf maximum; stroke: 0.25 inch nominal; operating temperature: -40 °C to +120 °C; enclosure: IP65; force linearity: ±3% full scale.
Functional Features Proportional force output; zero and span adjustment; spring-centered design; low hysteresis; vibration-resistant construction; continuous duty rating.
Application Scenarios Engine fuel rack actuation, gas engine throttle control, hydraulic pilot valve control, proportional flow valve actuation, governor fuel control.
Performance Parameters Force repeatability: ±1% full scale; response time: < 25 ms; hysteresis: < 4% full scale; temperature drift: < 2% per 50 °C.
Material Composition Mild steel housing with zinc plating, copper solenoid winding, stainless steel armature and pushrod, return spring, nitrile shaft seal.
Structural Characteristics Cylindrical solenoid body; centered pushrod output; mounting flange with bolt pattern; side electrical connector; sealed lead wires.
Working Principle Control current through the solenoid coil generates proportional magnetic force on the armature, producing linear output force against the return spring. Output force is proportional to input current over the operating stroke.
