Hirschmann MESAP 43650 Measuring Adapter

⚡ Test Solenoid Valves Without Shutting Them Down: The DIN 43650 Measuring Adapter Guide

Diagnose voltage and current problems on live Form A connectors with no disassembly, no downtime.

🚨 Guessing at a bad solenoid valve can cost you hours of downtime.

Without inline testing, technicians typically disconnect, test, reconnect, and re-test, adding crucial time during a diagnostic check. A measuring adapter cuts that time down while the valve stays powered and running.

🔧 What Is the MESAP 43650 Measuring Adapter?

The Hirschmann MESAP 43650 Measuring Adapter installs between a DIN 43650 (EN 175301-803) Form A female connector and your solenoid valve or device. It lets you check voltage and current in real time, while the valve keeps running, using standard 4 mm banana plug test leads.

✅ Compatible With:

  • Hirschmann GDM series connectors
  • HTP Form A connectors (look for H550Z in the part number)
  • 2 + ground and 3 + ground valve connectors

📦 Features:

  • Built-in short circuit bridge
  • CE approved
  • RoHS compliant
  • IP65 rated for dust/water resistance

📋 How to Use the Adapter: 3 Simple Steps

1
Install the adapter between the DIN 43650 female connector and the solenoid valve or device. No rewiring required.
2
Connect your banana plug test lead to the correct color-coded side of the housing (see below).
3
Read your meter (voltage or amperage) while the valve stays powered and operating normally.
⚫ BLACK SIDE = V
Connect here for a voltage reading
🔴 RED SIDE = A
Connect here for an amperage reading

Each side is clearly marked "V" or "A" on the housing, so there's no guesswork in the field.

🔌 Choosing the Right Banana Plug Test Leads

Compatible 4 mm banana plug test leads are available from Mueller and Hirschmann Test & Measurement in multiple configurations:

📏 Lengths: 12" to 60"
🎨 Colors: Red or black cords
🧷 End types: Test prods, plunger clips, alligator clips, double-ended banana plugs
🔩 Plug styles: Shrouded, un-shrouded, or stackable

Not sure which lead matches your meter? Use the test lead to meter cross reference chart to confirm compatibility before you order.

✅ Quick Reference Checklist

  • Confirm your connector is DIN 43650 (EN 175301-803) Form A
  • Match your circuit type: 2 + ground or 3 + ground
  • Black = Voltage, Red = Amperage: Always double-check the marking
  • Confirm test leads use standard 4 mm banana plugs
  • Stay within rated limits: 250V / 10A

🚑 Troubleshooting: Common Issues

No voltage reading at the black side?

Check upstream power and confirm the DIN connector is fully seated. A loose Form A connector is the most common cause of an intermittent or zero reading.

Amperage reading is unusually high?

This can indicate a failing solenoid coil drawing excess current. Disconnect power immediately if the reading approaches or exceeds 10A, as this is the adapter's rated maximum.

Adapter won't seat between connector and valve?

Verify you have a true DIN 43650 Form A connection, not a Form B/C or mini-connector. The MESAP adapter is Form A specific.

Not sure if it's safe to test live?

The MESAP adapter is IP65-rated and CE approved for exactly this use case, but always follow your facility's lockout/tagout and electrical safety procedures before working on energized circuits.
