Proximity Sensors Capacitive
High Temperature
Type ECH, M30
Product Description
• For temperature applications,
from -196°C to +180°C
• Sensor diameter: M30, teflon and stainless steel
• Adjustable sensing distance: 4 to 15 mm,
factory set for 10 mm
• Power supply: 10 to 40 VDC
• Output: transistor NPN or PNP, make & break switching
• Protection: Reverse polarity, short-circuit, transients
• LED-indication for output ON
• Separate amplifier and sensor
• Plug connection
Capacitive proximity switch
for non-flush mounting with
NPN or PNP open collector
output. The sensor is provided
with a separate teflon
sensor head in M30 for temperature
application within the
range of -196°C and +180°C
ambient temperature, e.g.
plastic pellet/resin detection in
plastic injection moulding machines
and drying equipment,
and detection of hot wax as
used in e.g. car manufacturing.
