EMX WEL-200-RX Wireless Edge Link Receiver Only
The WEL-200-RX is not a stand-alone safety edge. It is the receiver side of the EMX Wireless Edge Link system, and it must be paired with compatible WEL-200 transmitters and approved monitored sensing edges.
In the system, each transmitter sends the edge status wirelessly to the receiver. The receiver then interfaces with the gate or door operator using the supported monitoring output. This reduces the need for coil cords or cable carriers on moving gate sections while still supporting monitored edge requirements when configured correctly.
Correct compatibility depends on the WEL-200 generation, transmitter pairing, edge type, operator monitoring input, and line-of-sight mounting. The receiver should be replaced with the matching WEL-200R/WEL-200-RX style receiver when servicing an existing WEL-200 installation.

Technician Note
Receiver placement matters. Poor line of sight, metal obstruction, weak transmitter batteries, or incorrect channel assignment can make a good edge appear intermittent.
Before Ordering
- Confirm you need the receiver only, not the full WEL-200 kit
- Verify existing transmitters are WEL-200 compatible
- Check the operator safety input type and monitoring method
- Confirm line-of-sight mounting between receiver and transmitters
- Inspect all connected sensing edges before assuming the receiver has failed
Important Ordering Warnings
- Do not use the receiver to bypass a failed safety edge
- Wireless edge systems must still be wired and tested according to the operator and safety-edge instructions
Professional Advisory
For installation or replacement on a powered gate, door, or access-control system, follow the equipment manufacturer instructions and local safety requirements. If wiring, monitoring, or unsafe movement is uncertain, use a qualified gate or door technician.
Product Questions
Is WEL-200-RX the complete wireless edge kit?
No. WEL-200-RX is the receiver only. A complete system also needs compatible WEL-200 transmitters and monitored sensing edges.
How many transmitters can the WEL-200 receiver support?
WEL-200 system references commonly state that the receiver can connect with up to four compatible transmitters when configured correctly.
Can this receiver work with NC and 10K edge monitoring?
Yes, WEL-200 systems are commonly used with NC, 10K, and pulse monitored output configurations, but the exact setup must match the operator.
What is the related transmitter part number?
The related transmitter is commonly referenced as WEL-200-TX, WEL-200T, or EMX-4011-2.
What should be checked before replacing the receiver?
Check transmitter batteries, edge resistance, line of sight, pairing, dip-switch settings, and operator safety input wiring.
