Door Sensors - ASA ELECTRONICS INDUSTRY CO.,LTD

Home Product Info Magnetic proximity sensors Door Sensors

Features

・Compact-sized, highly-sensitive door sensors.
・High reliability and long functional life because of lack of physical contact.
・Any fast moving object detectable.
・Even in the case of incorporation into iron-made doors, capable of practical use by having a φ12 hole to let magnetism work.

Sensing distance

Door distance 22

The actual detecting distance can become longer depending on the surrounding conditions (iron material, etc.) The materials of nonmagnetic door include aluminum, SUS304, glass, wood and resin. You can choose the way to combine a Mag and a sensor; e.g. a Mag with magnetism from a lateral face and upward detecting sensor, the opposite combination, and so forth.

*By using cable options, conversion of output specifications, current amplification, and cable extension are possible.

・The circuit diagram must be observed to ensure a correct connection. A reverse connection and a short-circuiting output are strictly prohibited.
・When connecting an inductive load such as relay, be sure to use a freewheeling diode. (Some models already include a built-in freewheeling diode.)

・When installing a sensor, use the torque value designated for each sensor.

・When handling / using the product, do not apply an excessive tension to the cable connection part.
