3.2 Construction of Suitable Switch Rockers
For CAD system development support, 3D construction data of the rocker model of
Chapter 3.1 are available from EnOcean (IGS data)
.
Using this data, the mechanical interface is fixed, and the shape and surface of the rocker(s)
can be changed according to requirements. Recommendation for suitable rocker material is
Ultradur B 4520 with a surface roughness of min. Ra 1.0 ym.
3.3 Device Mounting
For mounting the PTM 200 device into an application-specific case, the package outline
drawings of the device are roughly dimensioned in 1.4 Mechanical Interface.
If more detailed dimensioning data of the PTM 200 device case is necessary, 3D
construction data is available from EnOcean (IGS data)
.
3.4 Transmission Range
The main factors that influence the system transmission range are type and location of the
antennas of the receiver and the transmitter, type of terrain and degree of obstruction of the
link path, sources of interference affecting the receiver, and “dead” spots caused by signal
reflections from nearby conductive objects. Since the expected transmission range strongly
depends on these system conditions, range tests should categorically be performed before
notification of a particular range that will be attainable by a particular application.
The following figures for expected transmission range are considered by using the PTM 100
radio transmitter device and the RCM 110 or RCM 120 radio receiver device with the
preinstalled whip antennas and may be used as a rough guide only:
•
30 m
for obstructed environment (e.g., through two brick walls inside a building)
•
300 m
for unobstructed environment (“free field”)
Further notes to determine the transmission range within buildings are available as download
