25 application data magnecraft ? pcb & reed relays introduction printed circuit board (pcb) relays are compact relay devices used for power management in control system designs which require the relay to be mounted directly on the printed circuit board ? they are used in applications where the relay must be small enough to be mounted on a printed circuit board ? they must be easy to manufacture with the same machinery used in the printed circuit board line ? how electromechanical pcb relays work electromechanical pcb relays consist of a coil, armature and contacts (see figure below)? when power is applied to the coil, the resulting magnetic field causes the armature to move and the contacts to open or close ? advantages higher contact ratings than reed relays and smaller than traditional plug-in relays ? a wider range of form, fit and function than reed relays ? ul recognized to meet industry standards for product safety and compliance ? how reed relays work reed relays consist of a coil wrapped around a sealed glass tube containing the reeds and contacts (see figure below) ? when power is applied to the coil, the resulting magnetic field causes the reeds to move and the contacts to close (1) ? advantages highly reliable due to longer mechanical and electrical life than ? electromechanical relays can switch about ten times faster than an electromechanical relay with ? similar ratings small, industry standard packaging which does not require unique machinery ? to populate (1) note that it is important to keep reed relays at a proper distance from each other because of the possibility of magnetic-interaction between them. proper magnetic shielding must be used to contain stray magnetic fields. when installing reed relays into equipment, be aware of the devices in the equipment which can produce magnetic fields. position the relays as far away as possible from any stray magnetic fields, and shield them to prevent false operations. a general rule is to space reed relays no closer together than 0.5 inches. electromechanical pcb relays vs. reed relays coil glass tube reeds mechanical contacts typical electromechanical pcb relay typical reed relay coil armature contacts
26 applications the magnecraft pcb relay offer consists of reed relays ideal for applications requiring fast, reliable low-level switching capability in a very small package, and electromechanical pcb relays ideal for applications requiring higher ratings than reed relays and a smaller package than traditional plug-in relays ? electronics & communication cellular phones, computers, copiers, microphones, radio transmitters, speakers industrial automation human/machine interfaces, motion controllers, plcs, power supplies, solder/wave reflow systems, variable speed drives hvac & refrigeration air conditioners, blowers, compressors, motorized ducts/vents, refrigerators, space heaters construction & security conveyor belts, elevators, emergency lamps, hoists, lifts, security alarms domestic appliances coffee machines, dish washers, food processors, microwaves, ovens, stoves, vacuum cleaners, washing machines automotive anti-lock brake systems, cruise control, doors, power steering, power windows, sunroofs application data (continued) magnecraft ? pcb & reed relays typical examples of pcb and reed relay applications
