HIMA BV7046-4 Connecting Cable for H41q System

The HIMA BV7046-4 Connecting Cable for H41q System is a factory-made system bus cable from HIMA Paul Hildebrandt GmbH (Brühl, Germany). It connects the H 7506 bus terminal (DIN-mount, 25-pole Mini-D connector) to the system interface of the H41q / H51q safety controllers (PES), including redundant configurations.

Key Features

• Purpose-built data link between H 7506 bus terminal and H41q / H51q PES interface
• Factory-terminated cable — no field assembly or crimping required
• Suits single-channel and redundant H41q / H51q bus topologies
• Part of the HIMA BV 7xxx cable family (BV 7040 / BV 7045 / BV 7046 / BV 7048 / BV 7049 / BV 7050) for bus terminals H 7505 / H 7506
• Length variant -4 (4 m per HIMA BV-series naming convention)

Installation Notes

1. Verify the cable variant (-0.5 / -1 / -2 / -4) matches the physical distance between the bus terminal and the controller interface before ordering.
2. Route the cable clear of power and field-signal wiring; avoid sharp bends and mechanical stress at the connector ends.
3. Seat the Mini-D connector fully into the H 7506 bus terminal and secure the retaining screws; torque within the manufacturer’s specification.
4. Connect the opposite end to the corresponding bus interface on the H41q / H51q rack per the plant wiring diagram.
5. After installation, verify bus communication status on the safety controller’s diagnostics; do not use the cable for any other signal path.

Common Questions

What is the BV7046-4 used for?

It links the H 7506 bus terminal to the system bus interface of an H41q / H51q safety controller, enabling the PES to communicate with field bus segments via the terminal.

Is the -4 suffix the cable length?

Per HIMA’s BV-series naming (e.g., B 9302-0,5 / -1 for 0.5 m / 1 m; BV 7040-4 for 4 m), -4 indicates the 4 m length variant. Confirm the exact length with the order specification.

Can this cable be used with HIMax?

The BV 7046 is documented for H41q / H51q systems. HIMax uses a different bus infrastructure — verify compatibility with the HIMax manual before use.
