*1. The Reflector is sold separately. Select the Reflector model most suited to the application.
*2. Values in parentheses indicate the minimum required distance between the Sensor and Reflector.

Reflectors

(A Reflector is required for each Retro-reflective Sensor: A Reflector is not provided with the Sensor. Be sure to order a Reflector.)

Name Sensing distance Model Remarks
Rated value Reference value
Reflector --- 15 m (300 mm) E39-R1 Retro-reflective models are not provided with Reflectors.
Separate the Sensor and the Reflector by at least the
distance given in parentheses.
The MSR function is enabled.
7 m (200 mm) --- E39-R12
--- 7 m (200 mm) E39-R6

Note: If you use the Reflector at any distance other than the rated distance, make sure that the stability indicator lights
         properly when you install the Sensor.

Mounting Brackets

A Mounting Bracket is not provided with the Sensor. Order a Mounting Bracket separately if required.
