Proximity Sensors Capacitive
High-temperature
Type ECH, M 30
Product Description
For temperature applications,
from -196C to +180C
Sensor diameter: M 30, 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 pro-
vided with a separate teflon
sensor head in M 30 for tem-
perature application within the
range of -196C and +180C
ambient temperature, e.g.
plastic pellet/resin detection in
plastic injection moulding ma-
chines and drying equipment,
and detection of hot wax as
used in e.g. car manufacturing.
