RF Transmitter datasheet and documents for STM320U
RF Transmitter Overview
The STM320U is an energy harvesting magnet contact transmitter module from EnOcean, designed for wireless open/close detection of doors and windows. It operates on the 902 MHz frequency band with FSK modulation at a data rate of 125 kbps. The module integrates a photovoltaic harvester and an internal energy store to ensure maintenance-free operation. It features a built-in spring antenna and is available in variants supporting different regional frequencies.
RF Transmitter Feature Summary
- Powered by an integrated solar cell for maintenance-free operation
- Enables wireless implementation of magnet contact sensors
- Includes an integrated energy store for uninterrupted functionality
RF Transmitter Applications
- Open or close detection of doors
- Open or close detection of windows
- Wireless magnet contact sensor implementation
RF Transmitter Procurement Notes
Verify the specific ordering code, such as S3001, against your regional frequency requirements. Confirm that the 902 MHz variant aligns with local regulatory standards. Ensure compatibility with EnOcean-based control systems. Check for any specific mounting or environmental constraints defined in the official user manual before finalizing procurement.
RF Transmitter Selection Notes
Select the STM320U when a maintenance-free, energy-harvesting solution for door or window monitoring is required. Choose this model over battery-powered alternatives to eliminate replacement costs. Ensure the application environment provides sufficient light for the solar harvester. Verify that the 902 MHz frequency is permitted in the deployment region.
RF Transmitter Part Context
The STM320U belongs to the EnOcean STM 32x family of energy harvesting modules. This family includes variants like the STM 320 and STM 329, which operate at 868 MHz. The STM320U specifically addresses markets requiring 902 MHz transmission. These modules are part of EnOcean's broader ecosystem of certified wireless communication products.
RF Transmitter Replacement Considerations
Public confirmed substitute part numbers: STM 320 (868 MHz variant), STM 329 (868 MHz variant). Note that these variants differ in operating frequency. Direct functional substitution requires verifying regional frequency compliance.
