Dual Mechanical Button Module

Name: Dual Mechanical Button Module
Brand: Dahua
SKU: VTO4103F-MB2

Stock Code: VTO4103F-MB2

Panel module with dual mechanical buttons

An outdoor module that adds two separate mechanical buttons to a modular panel system. The aluminum alloy body combines IK07 impact resistance with IP65 dust and water protection. It draws power from the other modules and passes 5 V DC to the modules on the same line.

IP65Protection Grade

IK07Impact Resistance

-30 °C to +60 °COperating Temperature

5 V DCPower Supply

≤0.5 WPower Consumption

100 × 50.0 × 30.50 mmDimensions

Key features

Dual mechanical buttonsThe module combines two mechanical buttons in one body and runs on an embedded processor.

Aluminum bodyThe aluminum alloy casing protects the module against outdoor conditions.

Modular powerIt draws power from the other modules and feeds 5 V DC to the modules on the same line.

Flush and surface mountIt supports both flush mount and surface mount installation.

Outdoor durabilityIt works outdoors between -30 °C and +60 °C and withstands 10% to 90% relative humidity.

Installation requires silicone sealant; the IP65 rating depends on it.
