Product Details
Omron Proximity Switch TL-Q5MC1 for Compact Metal Detection
The Omron Proximity Switch TL-Q5MC1 is a compact square inductive proximity sensor used for compatible metal detection, position sensing, automation hardware, electronics projects, and machine-control applications. It is commonly selected when a compact DC 3-wire sensor with NPN normally open output is required.
Precision Inductive Sensor with 5mm Sensing Distance
This Omron Proximity Switch TL-Q5MC1 has a listed sensing distance of 5mm ±10%. Omron identifies the TL-Q5MC1 as a rectangular standard proximity sensor with an unshielded square body and a recommended setting distance of 0 to 4mm. Always confirm the sensing target, mounting method, and installation clearance before use.
NPN Open Collector, Normally Open Operation
The TL-Q5MC1 is a DC three-wire proximity switch with NPN open collector output and normally open operation. This makes it suitable for compatible control boards, automation circuits, machine inputs, and electronics systems designed for NPN NO sensor wiring.
Useful for Automation, Machine, and 3D Printer Applications
This sensor can be used in a variety of compatible applications, including machine position sensing, metal object detection, automation fixtures, hobby electronics, CNC-style projects, and 3D printer hardware. The current dnb3D page lists it for the Voron 2.4 Stealthburner build, but compatibility is not limited to one printer platform. Always confirm voltage, wiring, output type, firmware settings, and physical fitment before installation.
Compact Square Sensor Body
Omron lists the TL-Q5MC1 sensing head size as 17mm x 17mm x 28mm. Its compact rectangular form factor helps it fit into tight mechanical layouts where space is limited and precise sensor placement matters.
Industrial Omron Sensor Specifications
According to Omron, the TL-Q5MC1 2M has an operating voltage range of 10 to 30 VDC, current consumption of 10mA max at 24 VDC, response time of 2ms max, and IEC IP67 protection rating. For full manufacturer details, review the official Omron TL-Q5MC1 product page.
Check Compatibility Before Wiring
Before installing this sensor, confirm that your controller or input device supports an NPN normally open inductive proximity switch. Incorrect wiring or voltage can damage electronics. If you are sourcing related control hardware, browse our 3D printer electronics category for compatible boards, modules, and accessories.

Installation & Care
Confirm Compatibility Before Wiring
Before installing the Omron Proximity Switch TL-Q5MC1, confirm that your controller, input board, PLC, printer control board, or electronics system supports a DC 3-wire NPN normally open inductive proximity sensor. Check your wiring diagram, voltage requirements, input logic, firmware settings, and sensor mount before connecting power.
Wiring and Electrical Safety
Use the sensor only within the correct voltage range and wiring configuration. Omron lists the operating voltage range as 10 to 30 VDC. Incorrect polarity, incorrect input type, over-voltage, or shorted wiring can damage the sensor or connected electronics. Disconnect power before wiring or adjusting electrical connections.
Sensor Positioning
This sensor has a listed sensing distance of 5mm ±10% and a setting distance of 0 to 4mm. For best results, mount the sensor securely and position the target within the recommended detection range. Ferrous metal targets provide the intended sensing response; sensitivity may be reduced with non-ferrous metals.
Mounting Clearance
Because this is an unshielded inductive proximity sensor, nearby metal can affect detection performance. Leave proper clearance around the sensing face and surrounding hardware where possible. Test the sensor after mounting to confirm repeatable triggering before relying on it for homing, positioning, or machine-control functions.
3D Printer and Machine Use Notes
This sensor may be used in compatible 3D printer hardware, automation projects, machine-position sensing, CNC-style fixtures, and custom electronics builds. Compatibility depends on the exact controller, input circuit, mounting design, firmware configuration, and target material. Do not assume compatibility based on connector appearance alone.
Handling and Storage
Keep the sensor clean and dry before installation. Avoid crushing the cable, pulling on the wire strain relief, striking the sensing face, or exposing the sensor to harsh chemicals. Store unused sensors in a clean parts organizer or sealed bag until needed.
Testing After Installation
After installation, test the detection indicator and controller input before running the machine or printer. Confirm that the sensor triggers consistently at the expected distance and that the connected system responds correctly.
