Technical data
Parameter
Value
Blind zone
0-65 mm
Sensing range
600 mm
Ultrasonic frequency
Approx. 400 kHz
Sonic frequency
3.7 Hz

Sensing range in centimeters
The dark gray areas (A) indicate the range in which
the standard
reflector (a tube) is reliably detected.
The light gray areas (B) represent the range in which
a large reflector (such as the lubricant surface) is still
detected provided that it is optimally aligned to the
sensor. No evaluation is possible outside the li
ght
gray area.
Operating voltage U
B
9-30 VDC (reverse polarity resistant)
Residual ripple
± 10%
No-load power consumption
≤ 60mA
Connection type
M12 connector, 5-pin
Response delay
272 ms
Readiness delay
< 300 ms
Enclosure rating per EN 60529
IP65 / IP67 (depending on the cable box used)
Operating temperature range
- 40 °C to + 70 °C
Switching points
Full signal D1; low-level signal D2 according to the reservoir size; pre-empty signal
D3
programmable upon customer request, preset to 10 mm above the low-level
signal (use is optional)
Conformity with standards
DIN EN IEC 60947-5-2
Display elements
LED green/LED orange
Switching output set/not set
Housing material
PBT, polyester, ultrasonic transducer: PUR, epoxy resin with glass contents
Switching output
3x pnp; UB-2V; lmax = 3 x 200 mA; NO contact, short-circuit proof
NOTE
The specified enclosure rating is contingent on the use of connection sockets and cables suitable for that enclosure
rating. If connection sockets and cables with a lower protection rating are used, the lowest of those protection ratings
will apply.
