Fotoelektrische vorklichtsensor Panasonic PM-T45 T-type, licht-/donkerschakelend, 5–24 V DC

Panasonic PM-T45 is a T-type photoelectric fork sensor designed for non-contact detection of small parts, labels and edges in automation and conveyor systems. The fork-style housing positions emitter and receiver in a compact U-shape to detect objects passing through the slot. The sensor supports both light-on and dark-on switching and operates from a low-voltage DC supply, making it suitable for integration into machine controls and sensing stations on production lines.

Advantages

The T-type fork format provides stable, repeatable sensing of thin or irregular items without physical contact. Dual switching modes allow flexible configuration to detect presence or absence depending on application needs. Wide supply voltage range and simple output behavior make the unit compatible with common PLCs and control circuits. The compact, open-slot design simplifies alignment and installation in tight spaces.

Suitable for

• Presence detection of small components on conveyors
• Label sensing and edge detection on packaging lines
• Counting parts or tracking items through processing stations
• Position verification in assembly and indexing applications

Key specifications

• Sensing configuration: fork (T-type) with emitter and receiver in open slot
• Switching modes: selectable light-on and dark-on
• Supply voltage: operates across a low-voltage DC range suitable for control systems
• Output type: switching output compatible with DC control inputs
• Mounting: compact slot design for inline or panel mounting where small parts pass through

How to use

Mount the PM-T45 so the object to be detected passes through the fork slot perpendicular to the optical axis. Select light-on or dark-on switching according to whether detection should occur when the beam is received or interrupted. Connect the sensor to the DC supply and the control input following the equipment wiring standards; verify output polarity and load requirements before powering. Adjust alignment so the target reliably interrupts or reflects the beam as required, then test detection across the expected range of part sizes and positions.

Recommendations

Install the sensor in a stable support to avoid vibration-related false triggers, keep the fork slot free of dust and debris, and provide appropriate shielding from ambient light where necessary. Verify switching mode and wiring compatibility with the machine controller prior to commissioning.
