Model TCA3050BL Flat Square Inductive Proximity Sensor Switch 2Wire NC 636VDC Overview A compact flat square inductive proximity sensor for reliable noncontact detection of metal targets. The TCA3050BL delivers simple 2wire normally closed switching and a wide operating voltage range for straightforward integration into DC control circuits. Key benefits Reliable noncontact detection: Detects metal objects without physical contact, reducing wear and maintenance compared to mechanical switches. Simple wiring and integration: 2wire normally closed output simplifies wiring to PLCs, relays, counters, and other DC control inputs. Wide voltage compatibility: Operates across 6 to 36 VDC to fit a broad range of industrial and automation power supplies. Spacesaving flat square design: Lowprofile form factor fits into confined mounting spaces and flush mounting arrangements. Durable, lowmaintenance operation: Designed for continuous sensing tasks where consistent switching behavior is required. Important attributes Function: Inductive proximity sensing for metallic targets; noncontact switch operation. Output type: 2wire normally closed (NC) switching. Supply voltage: 636 VDC. Form factor: Flat square sensor housing for compact installation. Model: TCA3050BL. Compatibility: Works with standard DC control circuits and inputs that accept 2wire NC sensors. Practical use scenarios Automated assembly: Detect the presence or absence of metal parts on assembly platforms to trigger downstream operations or sorting. Conveyor systems: Monitor passage of metal components on conveyors for counting, tracking, or indexing tasks. Machine position sensing: or supplement mechanical limit switches for position feedback on industrial machines and tooling. Installation and integration tips Mount the flat face toward the expected metal target and secure the sensor to a stable surface for consistent readings. Follow wiring conventions for 2wire NC sensors when connecting to controllers or relays; verify voltage compatibility within 636 VDC. Allow for correct sensing distance and target orientation in the mounting design to ensure repeatable switching. This model provides a compact, easytoinstall solution for metal detection and simple switching tasks in industrial automation and machinery control applications.
