E Series OMNI-BEAM™ Sensors
OMNI-BEAM Logic Modules
E Series OMNI-BEAM sensors easily accept the addition of timing logic when needed. Three
multiple-function logic modules are available. Model OLM5 is programmable for ON-delay, OFF-
delay, or ON/OFF-delay timing logic. Models OLM8 and OLM8M1 offer either one-short or delayed
one-shot functions. Programming of the logic function, the timing range, and the output state is
done via a set of four switches located on the logic module.
Both logic modules feature 15-turn clutched potentiometers for accurate timing adjustments. The
logic module simply slides into the sensor head housing and interconnects without wires. Timing
adjustments are easily accessible at the top of the sensor head and are protected by the sensor
head’s transparent, gasketed polycarbonate cover. Assembled sensors are rated NEMA 1, 2, 3, 3S,
4, 12, and 13.
OMNI-BEAM Logic Module Specifications
Operating Temperature: −40° to +70° C (−40° to +158° F)
Timing Adjustments: Two 15-turn clutched potentiometers with brass elements, accessible
from outside at top of sensor block, beneath gasketed cover.
Timing Repeatability: Plus or minus 2% of timing range (maximum). Assumes conditions of
constant temperature and power supply.
Useful Time Range: Useful range is from maximum time down to 10% of maximum, all
models. When timing potentiometer is set fully counterclockwise, time will be approximately
1% of maximum for models OLM5 and OLM8, and 2% of maximum for model OLM8M1.
Response Time: A disabled timing function adds no measurable sensing response time.
OLM5 Delay Timer Logic Module
Model OLM5 is programmable for ON-DELAY or OFF-
DELAY or ON/OFF DELAY timing functions. Each delay
function may be independently adjusted and separately
programmed for either a long or short adjustment range.

NOTE 1: if both ranges of either delay function are selected (i.e., if
both 1 second and 15 second switches are "on"), the delay time range
becomes 16 seconds, maximum.
NOTE 2: with switches #1 and #2 "off" (no ON-DELAY programmed),
ON-DELAY is adjustable from "negligible" up to 100 milliseconds,
maximum.
NOTE 3: with switches #3 and #4 "off" (no OFF-DELAY programmed),
OFF-DELAY is adjustable from "negligible" up to 100 milliseconds,
maximum.
The logic module slides into the sensor head
and interconnects without wires.

Plug-in timing logic modules are available for
either delay or pulse timing functions.
