JINGELAIKE Slot-Type Photoelectric Sensor

 

Model: BX-T52

---

 

1. General Description

 

The BX-T52 is a compact, U-shaped (slot-type) photoelectric sensor. It integrates an infrared emitter and a receiver into a single housing, designed to detect objects that pass through the slot. This design is highly reliable as it is not affected by the target’s color or surface gloss.

This model is a 4-wire sensor, providing complementary outputs (both Normally Open and Normally Closed), which offers greater flexibility for different control logic needs.

 

Key Features 🎯

 

• Slot-Type Design: Emitter and receiver are pre-aligned in a single U-shaped body.
• Dual Outputs: Provides both a Normally Open (NO) and a Normally Closed (NC) output.
• Wide Voltage Range: Operates on a standard 12 to 24 VDC supply.
• LED Indicators: Typically includes indicators for power (red) and output status (green or yellow).
• Applications: Ideal for edge detection, gear tooth counting, label detection, and precise object positioning.

3. Wiring

 

The label provides the wire color functions. Crucially, the label does not specify if the sensor is NPN or PNP. You must test this or check the documentation for your specific part. The wiring below shows both possibilities.

 

Wire Functions (from Label)

 

• Brown: V+ (12 – 24V DC)
• Blue: 0V (GND)
• Black: OUT (Main Output – typically Normally Open)
• White: NC (Inverted Output – Normally Closed)
