DATA SHEET

Technical Datasheet: wenglor P1MH101

Part Number / Type: P1MH101

Product Category: Photoelectric Reflex Sensor (Reflexsensor)

Measurement / Sensing Principle: Diffuse Reflection with Background Suppression (BGS)

1. Product Characteristics & Application

• Sensor Type: Photoelectric Reflex Sensor (Diffuse Reflection Sensor).

• Sensing Principle: Background Suppression (BGS). This optical setup allows the sensor to reliably detect objects of varying colors, shapes, or reflective surfaces within its range while completely ignoring background elements past the cutoff point.

• Sensing Range: 200 mm scanning distance.

• Housing Design: Ultra-compact rectangular block profile with dual top mounting holes.

• Special Features: Part of wenglor’s high-performance P1M compact series. It projects a precise, visible red light spot that makes target alignment effortless during installation. Ideal for tight installation spaces in robotics grippers, micro-part sorting, conveyor tracking, packaging machinery, and electronic component assembly lines.

2. Electrical Data

• Operating Supply Voltage ($U_B$): 10…30 V DC

• Electrical Design: DC PNP

• Output Function: PNP NC + NO (Antivalent/complementary dual outputs, providing both Normally Closed and Normally Open switching loops simultaneously).

• Approvals: CE Certified, UKCA, cULus Listed.

3. Performance & Protection Data

• Short-Circuit Protection: Yes

• Reverse Polarity Protection: Yes

• Overload Protection: Yes

• Switching Frequency: High cyclic response speed optimized for rapid target detection, small-part counting, and precise process synchronization loop logic.

4. Mechanical & Environmental Data

• Dimensions: Standard compact rectangular housing with a downward-facing connector port.

• Housing Material: High-grade robust industrial polymer compound with excellent shock and vibration resistance.

• Ingress Protection Rating: Ruggedized industrial sealing parameters (IP67/IP68 typical for the P1M family) against dust, moisture ingress, and typical factory lubricants.

• Ambient Operating Temperature: Tailored for standard factory automated environments.

• Manufacturer: wenglor sensoric GmbH, Germany.

• Batch / Reference Identifier: 1024R//1329410 (indicated on the product housing).

5. Electrical Connection & Wiring Layout

The sensor features an integrated standard downward-facing male circular plug connector hub (M8 × 1, 4-pin configuration).

Pinout Connection Mapping:

• Pin 1: Brown wire reference $\rightarrow$ + Supply Voltage Input (10…30 V DC)

• Pin 2: White wire reference $\rightarrow$ NC Output (Normally Closed PNP switching signal to load)

• Pin 3: Blue wire reference $\rightarrow$ – (0V Ground / Common Reference Line)

• Pin 4: Black wire reference $\rightarrow$ NO Output (Normally Open PNP switching signal to load)
