The Actuator/Sensor is a critical component in an Electrical Switch Module, serving two primary functions. As a sensor, it detects physical parameters such as position, pressure, temperature, or proximity, and converts them into electrical signals. As an actuator, it receives control signals and produces mechanical movement or action to operate the switching mechanism. This integrated component enables automated control and feedback in switch operations.
Typical sensing technologies include Hall effect, inductive, capacitive, or optical methods. The actuator portion may use electromagnetic, piezoelectric, or pneumatic principles to convert electrical signals into mechanical motion, which engages or disengages switch contacts.
Key parameters for selection include rated voltage (24 V DC ±10% per IEC 60947-5-2), current consumption (15–60 mA at rated voltage, no load), switching frequency (100–500 Hz), operating temperature (-40 to 85 °C per IEC 60068-2-1/2), degree of protection (IP54–IP65 per IEC 60529), mechanical life (10^6–10^7 cycles per IEC 60947-5-1), electrical life (10^5–10^6 cycles per IEC 60947-5-1), repeat accuracy (±0.05 mm per IEC 60947-5-2), housing material (PBT/PA66, UL 94 V-0), connection type (M12×1 per IEC 60947-5-2), weight (50–150 g), and operating pressure (1.0–1.6 MPa).
Materials on file include ferromagnetic core, copper windings, plastic housing, and stainless steel spring. These values are reference ranges; actual model-specific values must be verified with the legal manufacturer or supplier. Standards listed are procurement references and do not imply certification or compliance of any specific product.
The sensor portion uses technologies like Hall effect, inductive, capacitive, or optical sensing to detect physical changes and generate corresponding electrical signals. The actuator portion uses electromagnetic, piezoelectric, or pneumatic principles to convert electrical signals into mechanical motion, which then engages or disengages the switch contacts. This dual functionality allows the component to both sense and act within the switch module, enabling closed-loop control.
