The OP-88665 is an industrial-grade terminal block for relays, compatible with LY2N-D2 and similar series electromagnetic relays. It is used to optimize relay wiring layout and reduce circuit contact failures, adapting to circuit control scenarios of automated equipment. With a rated current of 12A and rated voltage of 250VAC/30VDC, higher than similar models, it can carry higher-power loads to ensure stable current transmission.​ Adopting a solder-free crimping wiring design, it is equipped with 10-way terminals, supporting 1.5-4.0mm² wire access. Fastened by a snap-on method, it improves wiring efficiency by 30%. The shell is made of flame-retardant PA66 material, with a temperature range of -25℃ to +90℃ and V0-level flame-retardant performance, which can self-extinguish within 3 seconds in case of open flame. It also has an anti-electric shock protection structure to enhance operational safety.
