Robertshaw 6000-105 Vibra Switch

The Robertshaw 6000-105 Vibra Switch is a high-precision vibration detection switch designed for heavy-duty protection of rotating and reciprocating machinery. Engineered for critical HVACR and industrial applications, this explosion-proof vibration switch (X-PRF) features a rugged aluminum housing rated for Class I, Groups C & D and Class II, Groups E, F & G hazardous locations. This unit utilizes a Single Pole Double Throw (SPDT) contact configuration and is compatible with 117V AC/DC control circuits. As a veteran-grade malfunction detector, it monitors both vibration amplitude and frequency, providing an immediate shutdown signal when levels exceed the user-defined threshold, effectively preventing catastrophic equipment failure from unbalanced loads or bearing wear.

Installation professionals value the Robertshaw 6000-105 for its field-adjustable sensitivity range of 0 to 4.5G, allowing for fine-tuning based on the specific operational profile of your motor, pump, or fan. The unit features both manual and remote electrical reset capabilities, ensuring operational flexibility after a trip event. With a wide temperature rating of -40°F to 200°F and an accuracy of ±5% of full range up to 300 Hz, this industrial vibration sensor provides reliable, maintenance-free performance in demanding environments.

Key Benefits:

• Hazardous Location Rated: X-PRF housing meets explosion-proof standards for Class I and Class II environments.
• Field Adjustable Sensitivity: Continuous adjustment from 0 to 4.5G to meet specific machinery vibration tolerances.
• Dual Reset Modes: Supports remote electrical reset (117V AC coil) and local manual reset for system integration.
• Rugged Durability: NEMA 4 equivalent weather resistance with an aluminum enclosure for long-term industrial use.
• Versatile Compatibility: Seamlessly replaces legacy Model 365-A8 units in existing control loops.

Common Questions:

Is the 6000-105 suitable for outdoor installation?
Yes, the Robertshaw 6000-105 is designed with a weatherproof and explosion-proof housing. However, for unsheltered locations where moisture or heavy rain is present, contractors often install a 6090-002 rainshield to provide additional protection.

What is the difference between this and the 6000-005 model?
The 6000-005 is a standard NEMA 4 weather-resistant model, whereas the 6000-105 is specifically explosion-proof for hazardous areas. Both utilize a 117V AC reset coil and SPDT switching.

How do I calibrate the trip point?
Technicians calibrate the unit by backing off the adjusting screw to find the "zero vibration point" while the machine is idle, then increasing the setpoint according to the equipment's normal operating vibration levels plus a safety margin.
