ISDN cable helos 018160 RJ-45 4-pin 0.25 m

ISDN cable helos 018160 RJ-45 4-pin 0.25 m is a short patch cable designed for reliable connections between ISDN telephony devices and network interfaces that use a 4-pin RJ-45 wiring. With a compact 0.25 m length, this cable is intended for close-proximity connections where minimal slack and tidy installation are required. The construction supports stable signal transmission for ISDN lines and short inter-device links in offices, communication closets, and equipment racks.

Advantages

The cable’s short length reduces signal attenuation and clutter in installations where devices are located near each other. A 4-pin RJ-45 termination matches common ISDN telephony pinouts, ensuring compatibility with standard ISDN interfaces. Robust connector housings provide secure mating and repeated plug cycles, while the compact form factor simplifies cable management in dense setups.

Suitable for

• Connecting ISDN telephony terminals and adaptors over short distances
• Patching between devices in communication cabinets or desktop setups
• Replacing worn short-range ISDN patch leads
• Situations that require minimal cable length to reduce clutter

Key specifications

• Connector type: RJ-45, 4-pin configuration compatible with ISDN pinouts
• Length: 0.25 m (25 cm)
• Usage: short-range ISDN and telephony patching
• Construction: molded connectors with strain relief for repeated use
• Suitable environment: indoor installations, equipment racks, desks

How to use

Insert the RJ-45 plug into the corresponding 4-pin ISDN port on each device until the connector latches. Ensure both ends are fully seated and that the cable is not bent sharply at the connector to avoid damage. Use the cable for short patching between telephony devices, ISDN terminal adapters, or network interfaces that require a 4-pin RJ-45 connection. Disconnect by pressing the connector latch and pulling the plug straight out to avoid strain on the cable.

Recommendations

For optimal performance, keep the cable free from heavy twisting and avoid running it alongside high-power electrical lines. Use this 0.25 m cable only where short reach is required; longer runs should use appropriately rated cables. Store the cable coiled loosely to preserve connector integrity and inspect connectors periodically for wear.
