CI Series QuickStart Guide

Compact Infrared Sensor

Use this QuickStart Guide for quick and easy mechanical 
installation, electrical wiring, and operation of the CI Series sensor.

Mechanical Installation

The CI Series sensors consist of the following components:
 

 C1 sensor

 

■ 

 2 mounting nuts

 

  1m (3ft) cable

Mounting Preparation

The CI sensor must be securely mounted to a vibration-free, 
mechanically stable support, away from motors producing large 
step-load changes. 

To prepare for sensor mounting:
 

  Select a mounting location that ensures the spot size is  

the same or smaller than the target. 

 

 Cut a 19mm (.75in) hole in the panel.

 

  Determine if you need Raytek® air purge or air/water  

cooing accessories. 

 When operating the CI sensor in ambient temperatures  
exceeding 70˚C (160˚F), water cooling is required. 

 

 If needed, attach accessories to the sensor.

 

 Have a 12-24 VDC 10mA power supply available. 

Mounting the Sensor

To mount the sensor:
 

  Screw 1 nut onto the sensor until it is more than halfway from 

the lens.

 ■

  Insert the sensor into the panel hole and screw on the 2nd nut.

 ■

 Aim sensor and tighten both nuts until sensor is secure.

Electrical Installation

There are three types of CI sensors. Each sensor (J Thermocouple, 
K Thermocouple, or the 10mV/˚C Voltage) has a different wire color 
system. Use one of the following charts specific to your sensor as 
a wiring guide.

Wiring

There is a 4-wire, PVC 
cable attached to the 
sensor. The cable holds 
two pairs of wires and a 
bare shield (

ground

) wire.
