Description
24V DIN 43650 Form A Connector Yellow LED + TVS – IP65
24V AC/DC DIN 43650 Form A electrical connector with integrated yellow LED indication and TVS transient voltage suppression, designed to protect solenoid valve control circuits from potentially damaging voltage spikes.
Manufactured to EN 175301-803 Form A, the connector combines a standard 2 pin + protective earth solenoid connection with a 400W peak TVS (Transient Voltage Suppressor) and highly visible yellow LED.
When an inductive solenoid coil is switched off, the collapsing magnetic field can generate a potentially high-voltage transient or back EMF. The integrated TVS provides fast voltage clamping directly at the solenoid connector, helping protect PLC outputs, electronic controllers, switches and other connected electrical equipment.
Rated for 24V AC/DC and 4A, the connector incorporates a transparent PA12 housing, PA6 GF contact holder, NBR gasket and PG9 cable entry suitable for 5–7mm diameter cable. IP65 protection is achieved when correctly assembled.
Electrical Specification
Connector type: DIN Form A
Standard: EN 175301-803 A
Description: P18 connector with screw terminals
Connection: 2P + PE
Protective earth position: H12
Rated voltage: 24V AC/DC
Rated current: 4A
Indicator: Yellow LED
Suppressor: TVS / Transil
TVS maximum breakdown voltage: 37.8V

The LED and TVS connected across terminals 1 and 2, confirm the suppression is located directly across the solenoid supply.
TVS Transient Voltage Suppression
TVS stands for Transient Voltage Suppressor. It is an electronic protection device designed to react rapidly to short-duration overvoltage transients.
Solenoid coils are inductive loads. When power is removed, energy stored within the coil's magnetic field is released and can produce a high-voltage transient, commonly referred to as:
✓ Back EMF
✓ Inductive kickback
✓ Switching transient
✓ Voltage spike
The integrated TVS clamps this transient voltage, helping prevent excessive voltage from reaching associated control equipment.
Why Use TVS Protection on a Solenoid Valve?
Modern industrial control systems increasingly use PLC transistor outputs, electronic switching devices and other sensitive semiconductor electronics to operate solenoid valves.
Placing the suppression device at the solenoid connector means the transient is controlled close to the source rather than relying entirely on protection elsewhere in the control system.
Potential benefits include:
✓ Reduced inductive voltage spikes
✓ Protection for PLC outputs
✓ Protection for electronic switches
✓ Reduced electrical stress
✓ Improved control-system reliability
✓ Reduced electrical interference
400W Peak TVS Protection
The integrated Transil TVS has a specified 400W peak power rating, with the manufacturer's data giving a maximum Vbr figure of 37.8V.
Under normal 24V operation the suppression device remains inactive. When a sufficiently high transient occurs, the TVS rapidly conducts and clamps the excessive voltage.
This fast response makes TVS suppression particularly suitable for protecting sensitive electronic control circuits associated with solenoid valves.
Yellow LED Status Indication
An integrated yellow LED provides immediate visual confirmation that electrical power is present at the connector.
This makes commissioning and fault diagnosis easier by allowing an engineer to quickly establish whether an electrical signal is reaching the solenoid valve.
The LED is particularly useful during:
✓ Commissioning
✓ Maintenance
✓ Electrical fault finding
✓ Valve testing
✓ Machine servicing

The IP65 rating applies when the connector is correctly assembled to the compatible counterpart.
DIN 43650A / EN 175301-803 Form A
The connector uses the standard EN 175301-803 Form A interface commonly known as DIN 43650A.
This standardised electrical connection is widely used on industrial solenoid valves and coils, allowing the LED + TVS connector to provide an easy protection upgrade for compatible 24V AC/DC solenoid valve installations.
TVS vs VDR Varistor Protection
Both TVS suppressors and VDR varistors are used to control voltage transients, but they operate using different technologies.
A VDR/varistor changes resistance as voltage increases and is widely used as a robust general-purpose suppression device.
A TVS semiconductor suppressor is designed specifically for rapid transient clamping and is particularly attractive where sensitive electronic control equipment is switching the solenoid.
For PLC and electronic control applications, the TVS version therefore gives you a useful alternative to the VDR connectors elsewhere in your DIN range.
Typical Applications
✓ 24V solenoid valves
✓ PLC controlled solenoid valves
✓ Pneumatic control valves
✓ Hydraulic solenoid valves
✓ Water control valves
✓ Process control valves
✓ Industrial automation
✓ Electronic control systems
✓ OEM machinery
✓ Packaging machinery
✓ Automated production equipment
✓ Sensitive control circuits
Why Choose the LED + TVS DIN Connector?
This DIN Form A connector combines electrical connection, visual indication and transient suppression in one compact component.
The yellow LED provides immediate confirmation that the 24V supply is present, while the integrated 400W peak TVS suppressor helps clamp potentially damaging voltage transients generated when the solenoid coil is switched off.
For 24V AC/DC solenoid valves controlled by PLCs or electronic switching equipment, it provides a particularly useful upgrade over a basic no-circuit or LED-only DIN connector.
With a 4A rating, PG9 cable entry, IP65 protection and standard EN 175301-803 Form A interface, it is suitable for a wide range of industrial automation and fluid-control applications.
