Description
Product Introduction
The Helmholz 700-600-CAN01 is an industrial-grade, 9-pin D-Sub bus connector specifically designed for high-reliability CAN, CANopen, and DeviceNet network wiring. Engineered by Helmholz, this compact 90° angled plug allows clean cable routing in tight control cabinets while ensuring signal integrity across high-speed industrial bus lines.
Featuring a built-in, slide-switch selectable terminating resistor, the 700-600-CAN01 simplifies network commissioning by allowing technicians to enable or disable line termination directly at drop nodes or end nodes without installing external resistors. Its rugged metalized housing provides electromagnetic shielding (EMI/RFI protection) in harsh motor drive and factory floor environments.

Application Scenarios & The “Trench” Experience
In an automated conveyor assembly or multi-axis servo system, CANopen communications frequently drop out due to loose cable connections, poor shielding, or improper network termination. Standard plastic D-Sub connectors often fail under continuous machine vibration or allow electrical noise from nearby VFD cables to induce bit errors.
Replacing cheap unshielded plugs with the Helmholz 700-600-CAN01 resolves transmission errors instantly. Its internal strain relief clamp secures dual CAN cables for daisy-chaining nodes, while the metallic housing grounds the cable shield directly to the D-Sub shell. If a node happens to be the last device on the segment, toggling the onboard termination switch to “ON” cleanly locks the network impedance without needing extra hardware.
Typical Applications:
- CANopen Machine Controls – Connecting PLC master modules to distributed I/O blocks and hydraulic valves.
- Variable Frequency Drives (VFDs) – Interfacing motion drives (e.g., Parker, Lenze, SEW) over CAN-bus.
- Mobile & Heavy Equipment Automation – Rugged sensor and controller cabling in industrial vehicle networks.

Transparency SOP: Quality Assurance & Testing
Every surplus or factory-new Helmholz 700-600-CAN01 connector undergoes a 5-stage physical and electrical inspection before dispatch:
- Housing & Thread Inspection: Verification of casing latches, D-Sub locking screws, and internal strain relief clamp integrity.
- Termination Switch Resistance Audit: Measuring internal resistance across CAN_H and CAN_L pins (120Ω verified when switch is ON; high impedance when OFF).
- Continuity & Short Testing: Point-to-point pinout continuity check across all internal screw terminal blocks.
- Mechanical Clamp Test: Ensuring terminal block screws turn freely and clamp securely on stranded 24-22 AWG field cables.
- Cleanroom & Protective Packaging: Sealed in protective bags to protect internal contacts from moisture and shop-floor debris.
The Veteran’s Tech Trap Guide (Crucial Value-Add)
⚠️ Check Termination Switch Position: Remember the cardinal rule of linear fieldbus topology—only the physical first and last devices on a CAN segment should have their termination switch set to ON (120Ω). Setting intermediate node connectors to “ON” drops bus impedance below acceptable limits and shuts down communication across the entire line.
❗ Proper Cable Shield Grounding: Always strip back outer cable insulation to expose the copper braid shield, and ensure it clamps tightly under the metallic strain relief clip inside the 700-600-CAN01 body. Floating shields act as antennas for electrical noise.
⚠️ Observe Pinout Standards: Verify your device’s D-Sub CAN pinout matches standard CiA specifications (Pin 2: CAN_L, Pin 7: CAN_H, Pin 3: CAN_GND). Do not mix up CAN_L and CAN_H during screw-terminal insertion, as reversed polarity will disable the node.
Frequently Asked Questions (FAQ)
Q: Does the Helmholz 700-600-CAN01 have a piggyback (PG) programming port?
A: No, the - suffix indicates a standard 90° connector without a pass-through PG socket on the rear. If you require a diagnostic programming port, look for the -CAN10 variant.
Q: Can this connector handle dual CAN cables for daisy-chaining?
A: Yes, the housing and terminal block are designed to accept two incoming/outgoing CAN cables to allow clean node-to-node loop wiring.
Q: What cable diameter range is supported by the strain relief?
A: Standard industrial 2-pair shielded CAN/DeviceNet cable (typically 4.5mm to 8.0mm outer diameter) fits cleanly within the cable clamp.
Q: What warranty coverage is provided?
A: We support every surplus and reconditioned Helmholz 700-600-CAN01 connector with a full 12-month operational warranty. If the unit fails continuity checks or physical latching within 365 days, we provide an immediate replacement or full refund.
