9 g6a low signal relay g 6 a precautions please refer to ?pcb relays common precautions? for correct use. long-term continuously on contacts using the relay in a circuit where the relay will be on continuously for long periods (without switching) can lead to unstable contacts because the heat generated by the coil itself will affect the insulation, causing a film to develop on the contact surfaces. we recommend using a latching relay (magnetic-holding relay) in this kind of circuit. if a single-side stable model must be used in this kind of circuit, we recommend using a fail-safe circuit design that provides protection against contact failure or coil burnout. relay handling when washing the product after soldering the relay to a pcb, use a water-based solvent or alcohol-based solvent, and keep the solvent temperature to less than 40c. do not put the relay in a cold cleaning bath immediately after soldering. double-switching load in two poles double-switching in two poles as shown in the figure below, one pole and two pole interval may become mbb (make before break) mechanically according to the timing of the point of contact switching (by the short-circuit mode), and the malfunction might be caused. in such a circuit, direct electric switching should be avoided, and concern for contact to be carried after the contact of relay absolutely switches in condition of no load. correct use lo a d cont a ct s + ? ? applic a tion ex a mple s provided in thi s doc u ment a re for reference only. in a ct ua l a pplic a tion s , confirm e qu ipment f u nction s a nd sa fety b efore us ing the prod u ct. ? con su lt yo u r omron repre s ent a tive b efore us ing the prod u ct u nder condition s which a re not de s cri b ed in the m a n ua l or a pplying the prod u ct to n u cle a r control s y s tem s , r a ilro a d s y s tem s , a vi a tion s y s tem s , vehicle s , com bus tion s y s tem s , medic a l e qu ipment, a m us ement m a chine s , sa fety e qu ipment, a nd other s y s tem s or e qu ipment th a t m a y h a ve a s erio us infl u ence on live s a nd property if us ed improperly. m a ke su re th a t the r a ting s a nd perform a nce ch a r a cteri s tic s of the prod u ct provide a m a rgin of sa fety for the s y s tem or e qu ipment, a nd b e su re to provide the s y s tem or e qu ipment with do ub le sa fety mech a ni s m s . omron corporation electronic and mechanical component s company contact: www.omron.com/ecb cat. no. k020-e1-10 0 8 12(0207)(o) note: do not u s e thi s document to operate the unit.
