E4R-A/E4R-2
Sensor 1
Sensor 2
E4R-A
Use shielded cables for the oscillator’s transmission line
(connected to the OSC terminals) and the reception line
(connected to the REC terminals). Each cable must be a
maximum of 20 m in length.
The shielded cables connecting the Sensor and terminals 7, 14,
and 6 (or 5, 12, and 4) must be all parallel conductors with 11
strands of 0.16-mm dia. each with all conductors shielded
independently. The cable connected to terminal 3 must be a
single-conductor cable that is 0.2 to 0.3 mm2in size.
Note: 1. Sensors 1 and 2 are in OR operation.
2. If only a single Sensor is connected, leave the termi-
nals for the other Sensor open.
3. Set the slide switch to CLOSE.
Note: CHECK terminal allows connection of oscilloscope for
trouble shooting ultrasonic signal.

JREFERENCE PULSE UNIT
Use the E4R-SP Reference Pulse Unit when more than one E4R-2 PowerSupply Unit is applied to a single application.The E4R-SP generates
reference pulses that synchronize a maximum of ten E4R-2 Power Supply Units in operation without mutual interference.
