Note: Use the E3X-MC11-S Mobile Console for the E3X-LDA Series Amplifier Units.
The E3X-MC11-SV2 is an upgraded version of the E3X-MC11-S that is fully interchangeable with the older model.
Refer to E3X-DA-S/MDA for details.

Beam Unit (for E3C-LD11/LR11)

A Beam Unit is not provided with the Sensor and must be ordered separately as required.

Applicable Sensor Head	Focus	Model
E3C-LD11	Line	E39-P11
E3C-LD11	Area	E39-P21
E3C-LR11	Line	E39-P31
E3C-LR11	Area	E39-P41

Reflectors (Required when using retro-reflective models)

A Reflector is not provided with the Sensor head. Be sure to order a Reflector separately.

Type	Appearance	Model
Standard Effective area: 23 × 23 mm *		E39-R12
Standard Effective area: 7 × 7 mm *		E39-R13
Transparent object detection Effective area: 23 × 23 mm *		E39-R14
