Kemo m241 vibration switch 12v dc

The Kemo m241 vibration switch switches 12v devices off in the event of vibrations (e.g. motor running noise) and switches them on with a time delay when they come to a standstill. For devices up to a current consumption of approx. 1000 mA. Indication via a flashing led. The vibration switch switches on e.g. signal horns, if a machine (e.g. pump) stops vibrating. Or a marten scare, if the vehicle has no more engine vibrations or driver vibrations and parks.

Function

To switch on signaling devices (e.g. flashing signal, sound signal) when an engine stops (no longer vibrates). The connected operating voltage 12v/dc (11-15v) is switched through to the output of the module after a short delay and the device connected there is thus switched on. If the module is operated e.g. at a construction site pump, then an alarm signal lamp can be switched on when the pump stops. Or in a motor vehicle, a marten scare can be switched on when the car is parked and automatically switched off when the car is moving (the engine is running).

Technical data

• Operating voltage: 11-15v DC
• Own current consumption: In vibration, engine running (led off): approx. 0,000005a (<5µA)
• At rest, no vibration (led flashing): < approx. 0.000008a (<8µA)
• Max. Switching current: 1a
• At rest, the input voltage is switched through to the output and the connected device is in operation
• Switch-off delay on movement: approx. 3 seconds
• Switch-on delay at end of movement: approx. 22 seconds
• Switching sensitivity: adapted to vibrations of approx. one car combustion engine
• Operating temperature range: approx. -20°C to +70°C
• Dimensions: approx. 60 x 45 x 20 mm (without mounting straps)

Mounting instructions:

The motor is mounted at a place where the vibrations are transmitted to the module and where it does not get too hot, e.g. on the air filter of a pump motor, in the engine compartment of a car, not directly near very hot engine parts (e.g. exhaust pipes). The 12v battery is used as the operating voltage. Please insert a fuse in the supply line between the vibration switch and the positive pole of the battery. The fuse should be built as close as possible to the 12v battery, so that also the supply line to the module is protected against mechanical damage and short circuit. The signal device is connected to the switching output of the module, which is then switched on (with a delay) when the motor to be monitored is no longer running. The current consumption of the connected signal device must not exceed 1a.
