DESCRIPCIÓN

DA1B05BWD is a 4-pin DIP/DF series reed relay manufactured by Aleph America, designed for general-purpose switching and control applications. The device features a nominal coil voltage of 12 VDC with a coil resistance of 500 ohms (±10%), an operating voltage maximum of 9.0 VDC, and a release voltage minimum of 1.0 VDC. It is housed in an industry-standard DIP package with transfer molding for environmental protection and is compatible with standard DIP handling, sorting, and PCB insertion equipment. The relay offers a maximum switching current of 0.5 A, maximum carry current of 1.0 A, and contact resistance of 0.15 ohms (initial), with an operate time of 1.0 mS maximum and release time of 0.5 mS maximum. Optional shielding and diodes are available, and UL models are offered for applications requiring regulatory compliance. This relay is well-suited for industrial control, instrumentation, and automation systems where reliable switching performance and compact form factor are essential.
