Overview

The ZS09R Zero Speed Switch Sensor is a self-contained device that combines sensor and switch for use in over speed, under speed, and zero speed applications. It senses magnetic and low carbon ferrous targets. Outputs are isolated and can be easily integrated with any controller or existing system. It is about the size of a prox switch, but incorporates intelligent speed sensing circuitry not found in simple on/off devices. Use the ZS09R Zero Speed Switch Sensor for switching logic inputs (PLC, DCS, etc.), or a single "Ice Cube" Relay (pilot duty only).

Operation

When motion is either detected or reaches setpoint (depending upon application), the relay output changes state. It remains in this state until under speed or zero speed condition occurs (depending upon application).
