Softline vs Hardline Quick Guide

• This is Softline (45358-07): Teflon jacket, flexible, to +204°C.
• Hardline alternative: Mineral insulation, stainless overbraid, to +649°C.
• Softline best for: Most industrial machinery under 200°C.
• Hardline best for: Gas turbines, furnaces, high heat areas.
• Softline flexibility: Easier to route in tight spaces.
• Hardline durability: Withstands mechanical abuse better.

Hardline Specifications Reference

• Hardline accelerometer connector: MS 3100R-10SL-4P with Viton.
• Hardline disconnect connector: Mates to MS 3106-10SL-4S.
• Hardline cable: Mineral insulated twisted shielded pair.
• Hardline protection: Stainless steel overbraid.
• Hardline cable temp: -54°C to +649°C.
• Hardline connector temp: -54°C to +427°C.

• Check before ordering: Verify both device connector types.

Installation Recommendations

• Connector torque: Hand-tighten only - no tools.
• Pre-connection check: Inspect pins for damage or debris.
• Keep clean: Wipe connectors before mating.
• Cable support: Use ties every 0.5 to 1 meter.

Frequently Asked Questions

• Q: What is the difference between 45358-07 and 45358-09?
  A: Only the length differs. 45358-07 is 7 meters, 45358-09 is 9 meters. Both use identical Softline construction, connectors, and temperature ratings. Choose 7m when your accelerometer and interface module are closer together to reduce excess cable.
• Q: Can I connect two Softline cables together for longer reach?
  A: Yes, using a bulkhead adapter or mating connector pair. Each connection adds signal loss and potential noise. For runs over 9 meters, consider moving the interface module closer or using a signal conditioner. Maximum practical length depends on your accelerometer output level.
• Q: Why is the interface module connector only rated to +93°C?
  A: The MS 3112-8-3P connector uses standard materials rated for -45°C to +93°C. This connector mounts on the interface module, which typically installs in a control panel or safe area away from high heat. Keep the module end below +93°C for reliable operation.
• Q: What does "potted connectors" protect against?
  A: Potting seals the rear of connectors against moisture, oil mist, dust, and corrosive vapors. In industrial environments, unsealed connectors eventually fail from contamination. Potted connectors last much longer, especially in paper mills, chemical plants, and offshore platforms.
• Q: Is this cable compatible with the 330400 accelerometer?
  A: Yes, the 330400 series accelerometers use the MS 3100R-10SL-4P receptacle. The 45358-07 mates directly. Check your specific accelerometer model. Some older models may use different connectors. When in doubt, verify the connector part number on your accelerometer.
