Description

The Siemens 3SE3020-1A is an open-type position switch equipped with snap-action contacts configured as 1NO (normally open) and 1NC (normally closed). It operates with a normal stroke, optimized for reliable actuation in industrial applications. The compact form factor features packaging dimensions of 42 x 45 x 97 mm and a lightweight design with a net weight of 0.042 kg, supporting ease of integration into constrained spaces.

This unit belongs to Siemens' product class 'C', indicating it is manufactured on demand but not reusable or returnable for credit. Designed for precise mechanical switching operations, the device ensures durability in environments requiring accurate positioning feedback and signal output.

Key specifications include robust engineering suited to high-performance settings where precise control signals are critical. Although discontinued as of October 2013, buyers are directed towards its successor model — the Siemens 3SE5250-0CC05 — for enhanced compatibility and up-to-date functionality. Comprehensive technical documentation is available to facilitate smooth transition or replacement processes within existing systems.

Engineers developing automation assemblies will find this positional switch suitable for tasks demanding dependable operation, compact design, and straightforward installation procedures.
