Overview

Type ECH Capacitive Proximity Switches, High Temperature
The type ECH capacitive proximity switches are supplied with a separate Teflon sensor head in M30 making them ideal for applications with an ambient temperature range of -196 to 180 °C. These could include plastic pellet/resin detection in plastic injection molding machines and drying equipment, and detection of hot wax as used in the manufacturing process of cars. They have been designed for non-flush mounting with NPN and PNP open collector outputs.
