Smith Systems, Inc. passive speed sensors (Magna-Tran ®)convert mechanical motion to an A/C voltage without the need of a power supply. These self-contained magnetic sensors produce a magnetic field which, when in the proximity of ferrous objects in motion, generate a voltage. The frequency of this voltage is directly proportional to the speed of the object in motion. (read more)

MSC Analog Variable Reluctance (VR) Speed Sensors are passive sensors and do not require any external power source. The sensor generates a sinusoidal output voltage proportional to target speed and air gap. (read more)

From 1 Watt to 200 Watts

• Transformers, Offline Switch-Mode (TSD & POL Series)
• Power Inductors, Low-Cost Toroidal (VTP Series)
• Filters
• Line Filters, EMI/RFI Common-Mode (PMCU Series)

Low-Profile Conveyors are ruggedly built to withstand the punishing duty of punch press and automated machine feed applications. But wherever they are used, these durable, compact units can increase material handling efficiency as they cut labor costs and downtime. You will even improve part quality by eliminating damage during batch transfer. (read more)

High output, High Sensitivity Passive speed sensors convert mechanical motion to A/C voltage without an external power source. These self-contained magnetic sensors produce a magnetic field which, when in the proximity of ferrous objects in motion, generate a voltage. When a magnetic sensor is mounted in the proximity of a ferrous metal target.. (read more)

Control and protection circuits have relied on variable reluctance technology for years. With few components and no moving parts, the passive magnetic speed sensors can provide a signal from the inside of an aircraft engine at temperatures approaching 425°C or from the hub of an automobile wheel at high shock and vibration.
