LR250 & PT250

MAXIMUM SENSOR LEAD LENGTH: 100 feet (30m) maximum;

The LR250 emitter and PT250 receiver are compact, totally-encapsulated opposed mode remote sensors whose 1/4" diameter smooth

barrel design and excellent operating characteristics make them ideal for many sensing applications. Mounting and alignment are

extremely simple, due to these sensors' wide field of view. The LR250 and PT250 may be mounted through a 1/4" (6,4mm) clearance

hole and held in place by a setscrew, or in a model SMB250 mounting block.

LR/PT250 series sensors are fully encapsulated, and have hermetically sealed lenses to eliminate internal condensation. Units may

be washed down without damage. Identical optical performance in different housing styles is available in models LR/PT200, 300, and

400 (see Banner product catalog).

The minimum object size required to break the beam of the LR250/PT250 opposed mode sensor pair is 1/8-inch. These sensors are

designed for use with Banner MICRO-AMP

modulated amplifiers, and MB Series amplifiers.

Hookup to MB Series Amplifiers

Banner remote sensors will connect to any MB Series amplifier. The model

MRB chassis (shown) has octal sockets for the amplifier and a BR-2 relay

(supplied) and provides power for the sensors and amplifier. Up to four sen-

sor pairs may be connected to one amplifier for light-operated OR or dark

operated AND operation. In multiple-sensor hookups, receivers are wired

in parallel and emitters are connected in series (see example for CM Series

modules, next page).

Several MB Series amplifiers are available. Each provides a different output

logic function. Chassis models with additional octal sockets are also avail-

able. Other types of output devices, including solid state relays, may be

ordered (see Banner catalog).

Remote Sensor Pair

Wiring rules:

1) Avoid running remote sensor cables in wireways together with

power-carrying conductors.

2) Avoid running remote sensor cables through areas of known ex-

treme electrical interference (electrical "noise").

3) Always use shielded cables and only connect the shield ("drain")

wire at the amplifier.

4) When splicing, never combine emitter and receiver wires into a

common cable. (The result will be electrical "crosstalk" within the

cable, which causes a "lock-on" condition of the amplifier.)
