Serial cable DELOCK 86879, D-Sub 37 pin to D-Sub 37 pin, beige, 2 m

DELOCK 86879 is a 2 m serial cable with male D‑Sub 37‑pin connectors on both ends in a beige jacket. It is designed to provide a fixed-length RS‑232/serial connection between devices equipped with 37‑pin D‑Sub interfaces, enabling point‑to‑point data transfer in industrial and legacy environments. The cable preserves the standard pinout required for communications and control signals between servers, instrumentation, PLCs, and other equipment that still use a 37‑pin D‑Sub connector.

Advantages

The cable offers a stable, fixed 2 m length that reduces signal variation from improperly extended leads and simplifies installation planning. Its molded D‑Sub 37 connectors ensure secure mechanical contact and reliable signal transmission. The beige outer jacket provides easy visual identification and blends with common equipment racks and panels. The construction is intended for dependable use in environments where a standardized 37‑pin interface is required.

Suitable for (tasks / use cases)

• Connecting legacy servers and workstations with 37‑pin D‑Sub serial ports
• Linking industrial instrumentation and measurement devices
• Interfacing control units, PLCs, and automation equipment
• Establishing point‑to‑point RS‑232 communication links
• Replacing or extending existing fixed‑pin 37‑pin D‑Sub serial cabling

Key specifications

• Connector type: D‑Sub 37‑pin to D‑Sub 37‑pin (male to male)
• Cable length: 2 m
• Color: beige
• Interface standard: RS‑232 / serial
• Cable use: point‑to‑point data and control signal transmission

How to use

Ensure both devices have compatible 37‑pin D‑Sub ports and that the RS‑232 pinout and signal levels match the equipment requirements. Power off devices before connecting the cable to avoid transient signals. Align the D‑Sub connector shell with the device port, insert the plug fully, and secure the connector screws by hand until firm to maintain mechanical stability. After connection, power on the devices and verify communication settings such as baud rate, parity, and handshake configuration to establish a stable serial link.

Recommendations

Avoid routing the cable alongside high‑voltage lines or heavy machinery to reduce electrical interference. For permanent installations, secure the cable to strain relief points and avoid sharp bends near the connectors. When used in industrial environments, check compatibility with device pinouts and grounding requirements to prevent communication errors.
