Sensing the world’s needs.
The tilt and tip-over switches and motion sensors are available as mercury metal and our patented non-mercury metal (patents #5.209.343 and #5.332.876.). Tilt switches are used to sense movement (tilt) of a device above and below a horizontal axis. Some applications include: level controls, appliances, security alarm systems, toys and games, float switches and water treatment equipment, portable lamps, PC anti-theft devices, vending-machine alarms and machinery security systems.
A reed switch consists of two ferromagnetic and specially shaped contact blades (reeds) positioned in a hermetically sealed glass tube 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), form C (changeover), and form B (normally closed). They are operated using a magnetic field generated by either a permanent magnet or current-carrying coil. Applications include sensors, relays, pulse counters and security devices.
Float switches are designed to fit into tanks or reservoirs containing fluids. They are used to monitor liquid levels by opening or closing when a desired action point is reached. They are operated by a magnet fitted into the float assembly and a Reed Switch fitted into the stem of the float body. 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.
A smart sensor has multiple sensors and multiple processing techniques to obtain and transmit more information than one could achieve from independent sensors. Smart sensors are extremely universal. They could be used in anything from consumer products to the automotive industry. Here at Comus International we customize our products to your specification. Whether it’s changing reaction time, g-force, or tilt control, our line of programmable sensors can give you the versatility needed for your application.
We manufacture a wide range of proximity switches that use either reed based, Hall effect or GMR technology. A reed based switch is activated by a magnetic field pulling the contacts either apart or together. Hall effect and GMR switches use electronic sensors and require a power supply to operate. The benefit of an electronic proximity switch is that an LED can be fitted to show the state of the switch. These switches are very sensitive. They can detect a ferrous metal from greater distances than reed based switches.
Our pressure switches use a diaphragm and small piston to push open or close a set of contacts. The switches come in either fixed pressure or adjustable by means of rotating a screw in the end cap. Pressure switches can be used to monitor pressure and can either trigger an over pressure cut out or low pressure warning condition.
