SW-18020P Vibration sensors - 5 pcs

A set of 5 pieces SW-18020P vibration sensors for detecting vibration. This is a really simple vibration switch, it is used very common in electronics toys, alarm, domestic appliance, electronics devices, smart home systems. It is based on Spring System which closes the connection between two terminals when the switch vibrates or shakes.

Electrical Specs:

• Voltage: less than12V
• Current: <20mA
• Conductive time: about 2ms
• Closed resistance: <10 ohm\
• Open resistance: >10M ohm
• Temperature range: Operating: -40 to 80’C
• Pull force of terminal: 500gf for 1 minute
• Humidity: 95% RH, 40°C for 96 hours
• Operating lifespan: above 200,000 cycles

Features:

• SW-18020 series is spring type, Non-direction vibration induced trigger switches, any angle can be trigger.
• The series of switches, at the rest is open circuit “OFF-state”, when the external force to touch and reach the corresponding vibration, or move in speed to reach the adequate centrifugal force. The conductive feet will be conduct instantaneously “ON-State”. When the external force disappear, the switches will be revert the “OFF-State”.
• Switch have the identification “P” at the bottom, for completely airtight;
• The series of switches, different model has different sensitivity.
• Suitable for the toys, anti-theft alarm system, electronics scales etc electronic product.
• The switch doesn’t have a direction, normally it’s open circuit inside, and it turns to close when it shakes instantly, and then turn to open again when motion is gone.
