Electronic vibration switch 686C01

programmable

Product overview
The 686C01 Smart Vibration Switch is a USB-programmable electronic vibration switch with configurable alarm threshold, delays and relay or MOSFET outputs. It serves as an electronic alternative to mechanical vibration switches for industrial machine condition monitoring and protection applications. The unit features a piezoelectric sensing element and a welded hermetic stainless steel housing rated IP68.

Key features

• USB programmable (see configuration sheet supplied with switch for exact settings)
• Alarm threshold range: 0.25 to 5 in/sec pk (4.5 to 90 mm/s rms)
• Frequency range: 2 to 1000 Hz
• Relay output: SPST, Form A or B MOSFET; latching or non-latching; normally open/closed options
• Power: 24 to 240 V DC/AC, 50/60 Hz
• Electrical connector: 2-Pin MIL-C-5015, top exit
• Internal sensing element: piezoelectric accelerometer
• Enclosure: welded hermetic stainless steel, IP68
