REK87

This is a low-current, electromagnetic, monostable, not polarized, hermetic relay with two change-over contacts, designed for switching DC & AC electrical circuits with frequency to 2500 Hz; models for space, military and general industry purposes as well as models with a higher leak integrity degree (symbol «◊») are available.

Production is carried out in accordance with state standard 16121-86 and ИДЯУ.647611.001 ТУ.

Environmental ratings: cold temperate and humidity conditions.

How to order: Relay REK 87 ИДЯУ.647611.001-01, ИДЯУ.647611.001 ТУ with symbol «◊».
