Technical Specifications: KNX RF Kinetic Switch

The Retrotouch wireless kinetic KNX ecosystem is powered by hardware developed by ZF Friedrichshafen AG. The system consists of two primary components: the KNX RF Push Button Module (AFIM-1010), which fits inside standard architectural switch frames and the KNX RF Programming Adapter (AFZM-0001), which is used temporarily during network commissioning.
.

1. KNX RF Push Button Module (AFIM-1010)

This module operates as a completely wireless, self-powered control node designed to inject telegrams directly into a KNX-RF1.R system topology to manage building technology applications like lighting and shutter control

Technical ParameterSpecification Value
RF Protocol Standard

KNX RF1.R (S-Mode compatible)

Operating Frequency

868.3MHz (+-21.7kHz)

Transmission Power (Tx Power)

-2 dBm

Modulation Scheme

FSK (Frequency Shift Keying)

Wireless Channels

1 Channel

Antenna Type

On-board PCB Antenna

Practical Indoor Range

Up to 30 meters inside buildings 

Operating Temperature Range

-20 C to +45 C

Software Programming Baseline

Configurable via ETS 5 (or newer) software tools

ETS Database Device Profile

"ZF Generic Pushbutton"

Physical Integration Compatibility

Form-factor matches industry-standard light switch frames and bezels

2. KNX RF Programming Adapter (AFZM-0001)

Because the push button module utilizes batteryless kinetic generation, it contains no internal power to hold open a wireless transceiver link when stationary
. The auxiliary programming adapter serves as a temporary power source to bridge bidirectional parameter downloads from the ETS 5 software suite
.

Technical ParameterSpecification Value
Primary Functional Purpose

Enforces configuration mode and supplies temporary power to the AFIM module

Battery Requirements

2x AAA Cells

Supported Battery Voltages

1.2 V (Rechargeable) or 1.5 V (Alkalaline)

Operating Temperature Range

-20 C to +45 C

Visual Status Indicators

On-board Red LED


• Solid Light: Device in configuration mode


• Flashing Light: Active ETS configuration download in progress

Physical Interlock System

Built-in mechanical reverse-polarity/anti-twist protection (Verdrehsicherung)

3. Physical & Safety Constraints

  • Mechanical Protection: Both the programming adapter and the push button module are stamped with a explicit "Top" alignment marker
    . Connecting the programming adapter upside down can override the mechanical protection layout and cause permanent physical degradation to the switch module's internal contact pins
    .

  • Electrical Maintenance: The exposed alignment pins on the underside of the pairing adapter must never be short-circuited or electrically bridged, as this will result in immediate battery discharge or failure during the pairing sequence
    .

  • Operational Restrictions: In accordance with industrial system regulations, this hardware is explicitly banned from deployment inside safety-relevant, life-preserving, or health-supportive medical facilities
    .

  • Regulatory Compliance: The system components are CE certified and compliant with the following European standardized guidelines: EN 300-220 SRD, EN 301 489-1/-3, and EN 60950-1
    .
