The Carlo Gavazzi Type ECH proximity sensor is a capacitive proximity switch for non-flush mounting with a PNP open collector output. The sensor is provided with a separate teflon sensor head in M30 for temperature applications between -196 to 180°C (-320 to 356°F).

Example applications include plastic pellet/resin detection in plastic injection moulding machines and drying equipment, and detection of hot wax as used in car manufacturing.
