Schubert & Salzer – 9010 – Limit Switch for Pneumatic Actuators

Overview

The Schubert & Salzer Type 9010 is a position indicator and limit switch assembly designed for optional attachment to pneumatic piston and diaphragm actuators. Available in mechanical (micro switch), inductive proximity, and Ex-proof inductive proximity versions, the Type 9010 provides reliable end-position feedback across a wide range of industrial valve automation applications.

The Type 9010 is offered in both standard and compact configurations and supports cable gland, plug socket, and direct cable connection methods. Its robust IP65/IP67 protection ratings and wide ambient temperature ranges make it suitable for demanding process environments.

Features & Benefits
