Proximity Switch Suppliers and Manufacturers

Proximity switches and sensors use a reed switch and a permanent magnet. Each is encased in a plastic housing for protection and ease of mounting. A classic use is sensing the opening of a door in a security system. A reed switch in the jamb and a permanent magnet in the door complete a circuit when the door is closed. Opening the door breaks the circuit. 14"x9"x12".

These switches have a normally open contact which closes when the switch reaches the acceleration/activation level. 14"x9"x12"

Float switches are used to monitor liquid levels by opening or closing when a desired action point is reached. A variety of types are available using mercury and non-mercury tilt switches and, also, permanent magnets and reed switches. Common applications include sumps, pump-control systems, bilge pumps, below ground vaults and irrigation systems. 14"x9"x12"

Tilt switches are used to sense movement (tilt) of a device above and below a horizontal axis. A typical use is in a thermostat. A glass mercury switch is mounted to a bi-metallic spring which expands and contracts with temperature. As the spring moves, the switch contacts pass through the horizontal plane, opening or closing to operate the furnace or boiler. The angle through which the switch must move for proper operation -the differential angle- is measured from the point of just make to just break; it is specified as a maximum. When selecting a tilt switch, it is important to ensure that the operating mechanism can move the switch through an angle greater than the differential angle. Some additional applications include: level controls, appliances, security alarm systems, toys and games, float switches and water-treatment equipment (non-mercury). 14"x9"x12"

A reed switch consists of two ferromagnetic and specially shaped contact blades(reeds) positioned in a hermetically sealed glass tube with a gap between them and in a protective atmosphere. The plated contact surfaces are isolated from the outside environment, which protects the contacts from contamination. Reed switches are available as form a (normally open) and form c (changeover), and are operated using a magnetic field generated by either a permanent magnet or current-carrying coil. The features that make the reed switch a valuable tool include compact size, low weight, quick response time, long life and low cost. Some common applications are: reed relays, automotive sensors, robotics sensors, security sensors and toys and games. They are also available in moulded packages affording protection from damage and in surface mount styles. 14"x9"x12" 4"x2 1/2"x1 3/4"

Tip over switches sense tilt over 360 degrees of a vertical axis. A common use is in portable heaters used in the home to prevent electrical shock or fire. When the heater tilts more than a specified angle, the switch operates turning the heater off. This angle, called the operating angle, describes the angle from vertical to the point of contact operation, subject to a tolerance, ie:45 degrees plus-minus 10 degrees(35 degrees to 55 degrees). Both normally closed(tilt to close) switches are available. Some additional applications include: portable lamps, pc anti-theft devices, vending-machine alarms and machinery security systems. 14"x9"x12"
