Description
DIN 43650 Form A Electrical Connector Red LED + VDR – IP65
Nass Magnet EN 175301-803 Form A electrical connector with integrated red LED status indication and VDR varistor surge suppression, designed for solenoid valves, solenoid coils and industrial automation equipment.
Available in 24V, 110V and 230V versions, this DIN Form A connector combines visual electrical status indication with a voltage-dependent resistor (VDR) to suppress potentially damaging transient voltage spikes generated when an inductive solenoid coil is switched off.
The connector uses the standard DIN 43650A / ISO 4400 Form A 28mm interface with 2 pin + protective earth connection, making it suitable for a wide range of compatible industrial solenoid valves and coils.
Current Nass designs feature a robust one-piece PA6 GF20 housing, M20 × 1.5 cable gland for 6–8mm cable, NBR profile gasket and IP65 ingress protection when correctly assembled.

*Maximum permissible current is also dependent upon conductor cross-section and installation conditions.
Red LED Status Indication
The integrated red LED provides clear visual confirmation when electrical power is being supplied to the connected solenoid coil.
This provides an immediate local indication of electrical status and is particularly useful during:
✓ Machine commissioning
✓ Fault diagnosis
✓ Routine maintenance
✓ Solenoid valve testing
✓ Industrial process monitoring
The LED circuit incorporates protection against incorrect polarity, allowing the appropriate connector version to be used with AC or DC supplies.
VDR Varistor Surge Protection
Unlike a standard LED-only DIN connector, this version incorporates a VDR – Voltage Dependent Resistor, also known as a varistor.
When a solenoid coil is energised, electrical energy is stored within its magnetic field. When the coil is switched off, the rapid collapse of this magnetic field can generate a high-voltage transient or inductive back EMF.
The VDR helps suppress this transient voltage.
During normal operation the varistor presents a high resistance. If the voltage rises above its designed threshold, its resistance falls rapidly, allowing transient energy to be diverted and the voltage spike to be clamped.
This helps protect associated electrical and electronic components from potentially damaging switching transients.
Why Use a VDR with a Solenoid Valve?
Solenoid coils are inductive loads and can generate significant transient voltages when de-energised.
Adding a VDR directly at the solenoid connector provides suppression close to the source of the transient.
Potential benefits include:
✓ Suppression of inductive voltage spikes
✓ Reduced back EMF
✓ Protection for PLC outputs
✓ Protection for relays and switches
✓ Reduced electrical stress on control equipment
✓ Improved control-system reliability
The Nass technical sheets explicitly identify the circuit as “LED + varistor” and the protection element as “yes, varistor.”
Housing & Construction
Housing type: One-piece
Housing colour: Opaque / milky
Housing material: PA6 GF20
Terminal block material: PA6 GF30
Contacts: CuZn, tin-plated
Contact resistance: <15mΩ
Gasket: NBR profile
Fastening screw: Steel 4.8
Protection: IP65 when correctly assembled
Ambient temperature: -25°C to +90°C
RoHS: Compliant
The current Nass specification confirms the PA6 GF20 housing, tin-plated CuZn contacts, NBR gasket and conductor capacity of 0.5–1.5mm².
Cable Connection
Cable gland: M20 × 1.5mm
Suitable cable diameter: 6–8mm
Cable gland material: PA6 GF30
Conductor cross-section: 0.5–1.5mm²
Cable gland tightening torque: 1.8 ±0.2Nm
For stranded and fine-stranded electrical conductors, suitable ferrules are mandatory to establish a secure electrical connection.
The conductor cross-sectional area also affects maximum permissible current capacity and must therefore be correctly selected for the electrical load.
Adjustable Connector Orientation
The protective earth connection is supplied in the 12h position as standard.
The internal terminal arrangement can be repositioned to provide:
✓ 12h
✓ 3h
✓ 6h
✓ 9h
This provides greater installation flexibility, allowing the electrical connector and cable outlet to be orientated to suit the position of the solenoid valve and surrounding equipment.

DIN 43650A / EN 175301-803 Form A
DIN 43650A, now commonly referenced as EN 175301-803 Form A, is one of the most widely used electrical connection formats for industrial solenoid valves.
Its standardised interface allows compatible connectors to be used across a wide range of solenoid coils and valve manufacturers.
This Nass Magnet version adds both visual LED indication and VDR transient suppression, providing additional electrical protection compared with a basic DIN connector without an internal circuit.
LED + VDR Compared with LED-Only Connector
For applications where only visual confirmation of electrical power is required, an LED-only DIN connector may be sufficient.
Where the solenoid is being switched by a PLC, relay, electronic controller or other sensitive control equipment, the LED + VDR version offers the additional benefit of suppressing the inductive voltage transient generated when the coil is switched off.
This makes the VDR version particularly useful for frequently switched solenoid valves and electronically controlled industrial machinery.
Why Choose the Nass Magnet LED + VDR Connector?
The Nass Magnet DIN Form A LED + VDR connector combines three important functions in one compact solenoid valve connection:
Electrical connection → Visual status indication → Transient voltage suppression
The integrated red LED allows engineers to see immediately when power is present, while the VDR varistor helps suppress potentially damaging back EMF generated by the solenoid coil.
Combined with IP65 protection, 24V/110V/230V options, adjustable earth orientation and the standard EN 175301-803 Form A interface, it provides a robust electrical connection for industrial solenoid valve installations.
