RF Transmitter datasheet and documents for PTM535U
RF Transmitter Overview
The PTM535U is an EnOcean RF transmitter module operating at the 902 MHz frequency band, designed for energy harvesting applications. It utilizes FSK modulation with a maximum data rate of 125 kbps and delivers an output power of 4 dBm. The module features an onboard whip antenna and is packaged as a surface-mount device (SMD). It supports EnOcean Alliance protocols and is intended for integration into self-powered wireless switches and sensors.
RF Transmitter Feature Summary
- Enables battery-free implementation of wireless switches and push buttons through integrated energy harvesting capabilities
- Provides reliable long-range communication in the 902 MHz ISM band suitable for North American regulatory compliance
- Features onboard whip antenna design to simplify PCB layout and reduce development complexity
RF Transmitter Applications
- Self-powered wireless switches for building automation systems
- Energy harvesting push buttons for industrial control panels
- Wireless sensor nodes requiring long-range transmission in unlicensed frequency bands
RF Transmitter Procurement Notes
Verify that the specific suffix 'U' denotes the 902 MHz variant with onboard whip antenna, distinct from other PTM535 variants such as the 2.4 GHz or 315 MHz versions. Confirm RoHS compliance status and ensure compatibility with target EnOcean gateway infrastructure. Check for any regional regulatory certifications required for deployment in specific markets.
RF Transmitter Selection Notes
Select this module when long-range communication in the 902 MHz band is required for North American deployments. Choose over other PTM535 variants if onboard antenna integration is preferred to minimize external component count. Ensure the application can provide sufficient mechanical actuation energy for the harvesting mechanism to function reliably.
RF Transmitter Part Context
The PTM535U belongs to the EnOcean PTM535 product family, which focuses on energy harvesting wireless transmitters. This family includes various frequency variants and antenna configurations to support different global regulatory requirements and application scenarios within smart home and industrial automation ecosystems.
RF Transmitter Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Users should verify pinout and protocol compatibility if considering alternative EnOcean modules or third-party solutions.
