The document introduces the features and characteristics of Coto Technology's 9007, 9081, 9081C, 9081C1 series SIP Reed relays, including hermetically sealed contacts, high dielectric strength, high speed switching, integral plastic housing, Form C and optional coil suppression diodes.
The 9000 Series Spartan SIP reed relays are economy‑type relays designed for compact, high‑speed switching in security, instrumentation and modem applications. Two main variants are offered: the 9007 series (general purpose) and the 9081 series (with optional Form C footprints and coil‑suppression diode). All models feature hermetically sealed contacts, high dielectric strength, and optional high‑sensitivity coil options.
The data sheet provides detailed electrical parameters, mechanical dimensions, and environmental ratings, including coil voltage options (5 V, 12 V, 24 V), contact ratings, insulation resistance, and operating temperature ranges. Optional features such as external magnetic shielding and diode protection are also described.
