• Manufacturer Part Number: OPEJ5
• Description: Sensor Power Block Module
• Manufacturer: BANNER ENGINEERING

Specifications of OPEJ5

• Accessory Type: Sensor Power Block Module
• Features: Prewired W/6-ft. PVC-jacketed 5-conductor Cable
• For Use With: E Series OMNI-BEAM Sensors

Chemical resistance of plastic fiber optic assemblies: contact with acids, strong bases (alkalis), and solvents will damage the monofilament
optical fiber acrylic core. The polyethylene jacket protects the optical fiber from most chemical environments; however, materials may migrate
through the jacket with long-term exposure. Samples of plastic fiber optic material are available from Banner for testing and evaluation.
Power Blocks with SPDT Form “C” Electromechanical Relay Output
OMNI-BEAM E Series power blocks provide regulated low voltage dc power to the
sensor head and logic module (if one is used), with input of 24 to 36V dc or 24 to 250V
ac (50/60Hz). All power blocks, except those designed only to power emitters, have an
internal electromechanical form “C” SPDT relay output.
Power blocks are epoxy-encapsulated and rated for 0° to +50° C (+32° to +122° F). They
feature limit switch style cross-hole design for front, back, or side mounting, plus a 30 mm
threaded hub for swivel bracket or through-hole mounting. Models include prewired cable
or quick-disconnect (QD) fitting (see models table). Assembled sensors are rated NEMA
1, 2, 3, 3S, 4, 12, and 13.
DC hookup is without regard to power supply
polarity.
Note: Cordset model MBCC-5.. is sold
separately for use with powerblock model
OPEJEQD. It has five wires. The white, black,
and yellow wires have no connection.
NOTE: E Series OMNI-BEAM sensor heads may also be
used with standard OMNI-BEAM power blocks with solid-
state output relay.
When E Series sensor heads are used with these power
blocks, the power block Alarm output functions as a
second load output that switches in parallel with the
Load output (DPST). If the power block is a dc power
block, neither output will have short-circuit or overload
protection. E Series sensor heads do not have a
D.A.T.A.™ display.

Application caution - Power block models OPEJ5(QD) and OPEJE(QD)
Power block modules OPEJ5(QD) and OPEJE(QD) use "partial phase firing" power conversion to enable their wide
range of ac input voltage (24 to 250V ac). AC power is applied to the sensor for only a small portion of each ac half-
cycle. The current demand during this period may be as high as 1 to 2 amps per sensor.
The collective current demand of several of these sensors on a common ac line is significant. If several sensors
are wired directly to the ac mains, it is unlikely that any adverse effects will be noticed. However, problems may be
noticed if several sensors are connected to a common circuit that is isolated from the ac mains by a transformer.
The collective peak current demand may rob other components on the same circuit of enough power to function
properly. In the worst case, a transformer with inadequate reserve current capacity may overheat. Barring a
transformer failure, the sensors themselves will operate normally.
NOTE: Peak power demand is not an issue when these power blocks are powered from direct current (24 to 36V
dc).
