DIN 43650 Solenoid Valve Connector Circuit Symbols

🔌 DIN 43650 Connector Reference Guide

DIN 43650 Solenoid Valve Connector Circuit Symbol Chart

Identify LED, diode, MOV, and bridge rectifier symbols fast so you can match the right DIN 43650 solenoid valve connector to your application.

DIN 43650 solenoid valve connectors can include built-in circuit options that change how the connector handles indication, polarity, and surge protection. These symbols may appear on connector housings or on product spec sheets for Form A, Form B, and Form C valve connectors. Use this chart to quickly identify the symbol, understand what it does, and choose the connector style that fits your application.

If you are selecting a new connector, compare the circuit symbol first, then confirm the voltage, connector form, and whether you need visual status indication or surge suppression. You can also view our DIN 43650 Solenoid Valve Connector Guide to get further details on which type you need.

✅ Quick Tips
  • LED = visual power indication
  • Diode = polarity-sensitive surge protection
  • MOV = overvoltage suppression
  • Bridge rectifier = AC to DC conversion within the circuit

Circuit Symbol Type
What It Means / When to Use It
DIN 43650 LED circuit symbol DIN 43650 LED indicator symbol DIN 43650 dual LED symbol
💡 LED
Best for visual power confirmation
  • Usually shown as a pair of triangles connected by a rectangle inside a circle.
  • Lets maintenance teams see at a glance when voltage is present.
  • Available on Form A, Form B, and Form C DIN 43650 connectors.
  • Some versions include dual LEDs.
  • Voltages include 10-50V, 12V, 24V, 110-120V, 230V, and 250V.
  • Can be used by itself or paired with a diode, MOV surge suppression, or bridge rectifier.

🔺 Diode
Best for polarity-sensitive suppression
  • Typically shown as a triangle with a line across the top.
  • Helps redirect voltage surges away from sensitive components.
  • Available for Form A, Form B, and Form C valve connectors.
  • Voltage options include 10-50V, 12V, 24V, and 230V.
  • Can be combined with LED indicators or bridge rectifiers.
  • Normally not paired with MOV surge suppression because both serve a similar protection role.

🛡️ MOV Surge Suppression
Best for overvoltage protection
  • Usually shown as a rectangle with a diagonal line across it.
  • MOV stands for Metal Oxide Varistor.
  • Protects the source and load from overvoltage surges.
  • Available for Form A, Form B, and Form C DIN 43650 connectors.
  • Voltage options include 24V, 110-120V, 230V, and 250V.
  • Can be used alone or paired with LEDs or bridge rectifiers.
  • Not typically used with diodes because both are used for surge protection.

🔷 Bridge Rectifier
Best for AC to DC conversion
  • Usually shown as a diamond with a triangle on each side.
  • Converts AC input into DC output inside the connector circuit.
  • Available for Form A and Form B valve connectors.
  • Voltages include 24V, 110-120V, 230V, and 250V.
  • Can be combined with LEDs, diodes, or MOV surge suppression.
  • Not found as a standalone component in these connector circuits.

📌 Making Use of This Chart

  1. Match or find the similar symbol on the housing or spec sheet.
  2. Confirm whether you need indication, suppression, or both.
  3. Check the connector form: Form A, B, or C.
  4. Verify the voltage rating before ordering.

🧰 Practical selection advice

  • LEDs indicate when power is present and active.
  • Diodes are used when polarity and coil protection are important.
  • MOVs provide broad overvoltage suppression.
  • Bridge rectifiers are used when AC input must be converted to DC.
  • For molded cable versions, double-check cable length and ingress protection before purchase.
