COMUS

Reed switches, magnetic sensors and position switches

About the manufacturer

Comus International is a manufacturer of sensors and switching components with a history dating back to 1978. The company began with tilt switches and subsequently expanded into a broad portfolio of solutions for detecting magnetic fields, motion, position and liquid level.

Today, Comus offers reed switches, reed relays, proximity sensors, tilt and vibration sensors, liquid-level sensors and custom sensing solutions. These products are used where contactless or hermetically sealed detection of position or state is required.

Reed technology combines very low power demand with contacts sealed from the external environment. This makes it widely used in alarm systems, meters, appliances, automation equipment and many battery-powered devices.

Applications

Comus solutions are used wherever reliable detection of a magnet, movement, position or liquid level is required. Typical applications include:

Alarm systems – door and window contacts and opening detection.
Industrial automation – position detection for moving parts, guards and actuators.
Meters and measuring equipment – pulse-based position and motion detection.
Home appliances – door, cover and lid detection.
Battery-powered devices – low-power switching and sensing without continuous sensor supply.
Liquid-level monitoring – float switches and protective sensing functions.
Medical and laboratory electronics – hermetically sealed position and detection elements.

COMUS products available from Maritex

Maritex offers COMUS reed switches and magnetic sensing components for position and state detection. These parts are well suited to simple, reliable input circuits, particularly where low power consumption and long mechanical life are important.

Available product groups include:

Miniature glass reed switches.
SMD reed switches.
Through-hole reed switches.
Components for magnetic-field and position detection.

One example in the Maritex range is the miniature RI-70SMD reed switch for surface mounting. Its compact size supports use in small devices and sensing assemblies integrated directly onto a PCB.

When selecting a reed switch, consider magnetic sensitivity in AT, switching current and voltage, contact power, mounting style and dimensions. The magnet strength and its position relative to the sensor should also be matched to the application.
