Description
DIN Form A Bridge Rectifier + VDR Connector 0–230V – IP65
The Nass Magnet 611-201-0307 is an EN 175301-803 Form A electrical connector incorporating a full bridge rectifier and VDR varistor surge protection for solenoid valves and coils.
Designed to convert an AC electrical supply into a rectified DC output directly at the solenoid coil, the connector provides a compact alternative to installing a separate external rectifier. Its wide 0–230V +15% voltage range and maximum operating current of 1.5A make it suitable for a broad range of industrial solenoid valve and automation applications.
Unlike the LED bridge rectifier version, the 611-201-0307 does not incorporate an LED indicator. It combines a full bridge rectifier with a VDR varistor on the input and protective diodes on the output.

The varistor is across the input feeding the bridge rectifier, with rectified positive and negative outputs to the solenoid coil.
Full Bridge Rectifier – AC to DC Conversion
The integrated full bridge rectifier converts an alternating AC input into a full-wave rectified DC output.
This enables a compatible DC solenoid coil to be operated from an AC control supply without requiring a separate external bridge rectifier.
The rectification takes place directly within the DIN connector, providing a compact solution particularly suited to solenoid valves, pneumatic valves, hydraulic valves and industrial automation equipment.
VDR Varistor Surge Protection
The connector incorporates a VDR varistor on the electrical input.
Solenoid coils are inductive loads and can generate potentially damaging voltage transients during switching. The varistor helps clamp excessive transient voltage, reducing electrical stress on associated components.
The Nass circuit also incorporates diodes on the output, providing additional protection as part of the rectifier circuit.
This gives the connector two important functions in a single DIN plug:
AC-to-DC Rectification → Transient Voltage Protection
Why Use a Bridge Rectifier Connector?
Installing the rectifier directly within the DIN connector can simplify solenoid valve wiring and eliminate the need for a separate external rectifier.
Advantages include:
✓ Operates compatible DC coils from AC supplies
✓ Rectification directly at the solenoid coil
✓ Integrated VDR transient suppression
✓ Reduces external electrical components
✓ Compact DIN Form A installation
✓ Simplifies machine and control panel wiring
✓ Suitable for replacement and OEM installations
It can also allow machinery to be standardised around DC solenoid coils while accommodating AC control supplies where required.

Protective Earth & Connection
Protective earth position: 12h standard
Contact spacing: 18mm
Poles: 2 + PE
As with the other Nass Form A connectors in this series, the internal terminal arrangement can be repositioned during assembly where required to provide:
✓ 12h
✓ 3h
✓ 6h
✓ 9h
This provides installation flexibility where the solenoid coil or cable entry orientation requires an alternative earth position.
Environmental Specification
Ingress protection: IP65 to IEC 60529
Ambient temperature: -25°C to +90°C
RoHS: Compliant
IP65 protection applies when the connector is correctly assembled and mounted to a suitable mating device.
Installation Requirements
For stranded or fine-stranded conductors, suitable ferrules must be used.
Nass also states that conductor cross-section affects the maximum permissible current-carrying capacity and must therefore be considered when selecting wiring for the installation.
Typical Applications
✓ Solenoid valves
✓ AC operated DC solenoid coils
✓ Pneumatic directional valves
✓ Hydraulic solenoid valves
✓ Process control valves
✓ Water control systems
✓ Industrial automation
✓ OEM machinery
✓ Packaging equipment
✓ Pumps and fluid systems
✓ PLC controlled machinery
✓ Industrial control equipment
Bridge Rectifier + VDR vs LED Version
This Circuit 08 connector is intended where rectification and transient protection are required but visual electrical indication is unnecessary.
The configuration is:
611-201-0307 → Bridge Rectifier + VDR → No LED
The alternative Circuit 09 version adds an LED:
611-201-0308 / 0309 → Bridge Rectifier + VDR + LED
Why Choose the Nass Magnet 611-201-0307?
The Nass Magnet 611-201-0307 combines a full bridge rectifier and VDR transient protection within a standard DIN Form A solenoid valve connector.
It provides a simple way to convert an AC control supply into rectified DC directly at a compatible solenoid coil while simultaneously helping protect the electrical circuit against switching transients.
With its 0–230V +15% operating range, 1.5A maximum operating current, M20 cable entry and IP65 protection, it provides a compact and versatile solution for industrial solenoid valve, automation and OEM applications.
