YOKOGAWA 16137-188

Description

YOKOGAWA 16137-188 is a specialized connector, cable assembly, or wiring accessory designed for Yokogawa’s industrial process instrumentation and control equipment. This specific part number, 16137-188, is a critical interface component that ensures reliable electrical connections, signal integrity, and environmental sealing for field devices or system modules. Detailed specifications can be found on the product page: YOKOGAWA 16137-188. The YOKOGAWA 16137-188 is essential for proper installation, maintenance, and the long-term reliability of the connected system.

Product Description

The YOKOGAWA 16137-188 is a precision-engineered connection component, most likely a pre-fabricated cable with molded connectors, a junction adapter, or a terminal housing. It is designed to mate with specific Yokogawa devices, such as pressure or temperature transmitters, analyzers, or controller I/O modules. The part serves as the physical and electrical bridge, for example, between a sensor head and a signal converter, or between a field device and a fieldbus junction box. The 16137-188 incorporates correct pin assignments, robust shielding, and often an IP-rated environmental seal to protect against moisture, dust, and chemicals. Its design ensures that the electrical characteristics are optimized for the signal type, whether it’s a low-level analog measurement, a digital communication signal, or power.

Product Parameters

• Brand and Manufacturer: YOKOGAWA.
• Product Type: Connection Cable Assembly, Connector Kit, or Wiring Accessory.
• Compatible Equipment: Designed for use with a specific Yokogawa device model or series (e.g., a particular model of EJA pressure transmitter, a conversion unit for an analyzer, or a remote I/O module).
• Connector Types: Specific male/female connectors, potentially featuring threaded couplings for secure and sealed mating (e.g., M12, M20, or proprietary Yokogawa fittings).
• Cable Specifications:
  • Conductors: Defined number of wires (e.g., 2-wire for 4-20mA with HART, 4-wire for power and signal).
  • Shielding: Integral shielding for electromagnetic compatibility (EMC).
  • Jacket: Industrial-grade material (e.g., PUR for oil and chemical resistance).
• Length: A specific standard length, potentially indicated by the suffix (e.g., ‘-188’ may encode a length or variant).
• Electrical Rating: Rated voltage and current for safe operation.
• Environmental Rating: Typically features an IP67 or IP68 rating for protection against dust and water ingress.

Advantages and Features

The primary advantage of the genuine YOKOGAWA 16137-188 is guaranteed compatibility, performance, and reliability, preserving the design specifications of the original equipment. It ensures perfect mechanical fit, correct electrical pinout, and maintains the system’s signal integrity and noise immunity. Key features include molded strain relief to prevent cable damage, robust connectors that withstand vibration and frequent mating cycles, and environmental sealing that allows installation in harsh outdoor or washdown areas. Using the YOKOGAWA 16137-188 eliminates installation errors, reduces commissioning time, and helps maintain the equipment’s warranty and safety certifications. It is a designed system component, not a generic cable.

Application Cases in Various Fields

• Pressure Transmitter Installation: Connecting the remote diaphragm seal of a Yokogawa EJA pressure transmitter to its main electronics body in a high-temperature or corrosive application.
• Fieldbus Device Connection: Serving as the drop cable to connect a Foundation Fieldbus or PROFIBUS-PA field device to a field junction box or trunk.
• Analyzer Integration: Providing the sealed connection between a process analyzer’s sensor and its remote processing or power unit.
• I/O Module Harness: Acting as a pre-terminated harness to connect a remote I/O module to its terminal base or power supply.
• Maintenance and Replacement: Used as an exact replacement part to restore a damaged or degraded connection during system maintenance, ensuring original performance.

Comparison with Competing Products

There are no true “competing products” in the open market for a proprietary accessory like the YOKOGAWA 16137-188. The alternative is field-fabricating a cable or using generic connectors. This carries significant risks: incorrect pinouts can damage equipment, poor shielding can lead to signal noise, and lack of proper sealing can cause premature failure in harsh environments. Generic connectors may not have the correct mechanical keying, thread type, or material compatibility. The 16137-188 is the engineered solution that guarantees the connection will perform as an integral part of the Yokogawa system. Its value is in risk mitigation, reliability, and preserving the performance of the often-expensive primary instrument.

Selection Suggestions and Precautions

1. Verify Exact Compatibility: This is the most critical step. The part number 16137-188 must be cross-referenced with the specific Yokogawa device’s installation manual or spare parts list to confirm it is the correct accessory for your exact device model and application. Do not assume compatibility.
2. Check Length and Configuration: Verify that the cable length and connector genders (male/female) are suitable for your physical installation layout.
3. Inspect Before Installation: Upon receipt, inspect the 16137-188 for any shipping damage to the connectors, cable jacket, or sealing surfaces.
4. Follow Torque Specifications: If the connector has a threaded coupling, use a torque wrench to tighten it to the manufacturer’s specified value to ensure a proper seal without damaging the threads.
5. Ensure Proper Sealing: Before mating, check that all O-rings or gaskets are present, clean, and properly seated. Apply cable gland seals correctly if applicable.
