Electro Sensors 115VAC 50/60Hz 4.6Va Speed Sensor M100

Electro-Sensors M100 Shaft Speed Switch

The Electro-Sensors M100 Shaft Speed Switch is a reliable device designed to monitor the rotational speed of shafts in various industrial applications. Operating at 115 VAC with a frequency of 50/60 Hz and consuming 4.6 VA, this speed switch ensures accurate detection of shaft speed variations, enhancing equipment safety and performance.

Key Features

• Easy Installation and Calibration: The M100 is engineered for straightforward setup and adjustment, minimizing downtime during installation.
• Rugged Construction: Built to withstand harsh environments, the device is dust, dirt, and grease-proof, ensuring durability in demanding conditions.
• Failsafe Operation: Designed to operate in a failsafe manner, the M100 provides reliable monitoring to prevent equipment damage due to rotational failures.
• Explosion-Proof Housing: The cast aluminum housing is rated for Class I, Div I (D), Class II (E, F, G), and Class III environments, offering protection in hazardous locations.

Technical Specifications

• Input Power: 115 VAC, 50-60 Hz
• Power Consumption: 4.6 VA
• Setpoint Range: 10 to 100 RPM
• Output Type: SPDT relay, 5 Amp at 115 VAC resistive load
• Setpoint Adjustment: Single-turn (270°) potentiometer

Applications

The M100 Shaft Speed Switch is ideal for monitoring shaft speed in various industrial equipment, including:

• Drivetrains
• Power-driven components
• Crushers
• Exhaust fans
• Screw conveyors
• Tail pulleys on belt conveyors and elevator legs

By detecting rotational failures such as broken drives, belt slippage, product overloads, clogs, and jams, the M100 can trigger equipment shutdowns or alarms, enabling proactive maintenance to prevent equipment damage, product waste, and excessive downtime.

Note

For new designs and replacements, Electro-Sensors recommends the M100T or M5000T models, which offer additional features such as optional voltages and a terminal strip for easier installation.
