Heschen Photoelectric Sensor E3F-DS10P1 M18 10cm DC 10-30V PNP NO 3-Wire

PRODUCT OVERVIEW: The Heschen E3F series M18 cylindrical diffuse reflection photoelectric proximity switches are industrial-grade, non-contact optical sensor modules engineered for high-speed object detection, automatic packaging counting, travel limit controls, and machinery feedback loops. Built with standard 18mm thread bodies and integrated 150cm (59") heavy-duty double-shielded cables, this matrix series offers unparalleled durability, minimal installation footprint, and robust signal reliability for demanding factory automation panels. COMPREHENSIVE SPECIFICATION AND VARIATION MATRIX: - Mechanical Footprint: Standard M18 threaded cylinder profile; fits exact 18mm diameter mounting cutouts. - Cable Specification: 150cm (59 inches) long-reach premium copper core integrated cord. - Load Driving Capacity: Steady 200mA current output. - Structural Range Layouts: 10cm fixed (unadjustable), 10-30cm adjustable (with trimmer), and 2m long-range adjustable configurations. - Electrical Configuration Varieties: DC 10-30V NPN (NO, NC, NO+NC 4-wire) / DC 10-30V PNP (NO, NC, NO+NC 4-wire) / High-voltage AC 90-250V Two-Wire (Normally Open or Normally Closed) setups. CRITICAL DC 3-WIRE AND 4-WIRE WIRING WARNINGS: For DC variants operating under the stable 10-30VDC threshold, please strictly match output logic to your controller PLC card inputs. To prevent direct short circuits and permanent internal semiconductor damage, never connect the load wires directly across positive and negative power rails without inserting a proper downstream coupling relay, solenoid coil, or digital PLC input resistance. CRITICAL AC 2-WIRE RESIDUAL CURRENT NOTICE: High-voltage AC 90-250V variants run on simplified 2-wire series circuits. Please note that a minor leakage current exists when the sensor is de-energized (OFF state), and a slight residual voltage drop occurs when it is energized (ON state). To avoid continuous chattering or failure to release, please verify that your coupling contactor, starter coil, or high-impedance relay minimum threshold parameters accommodate these standard 2-wire electrical characteristics. OPAQUE TARGET RESTRICTIONS AND OPTICAL CALIBRATION: Optimized as diffuse reflective sensors, these modules directly detect targets via face reflection without requiring mirror reflector plates. For flawless operation, target objects must be opaque (such as cardboard cartons, metallic sheets, dark plastics, or wooden pallets). High-translucency media, clear glass, transparent stretch wrap films, or translucent liquids will not return sufficient infrared light to actuate the sensors. For adjustable 30cm and 2m models, please use the rear-mounted sensitivity trimmer to dial in the ideal trigger threshold according to your target material's surface reflectivity.

• Complete Specs: Model E3F-DS10P1 M18 threaded housing fitting standard 18mm mounting holes; operates on a stable DC 10-30V control voltage with a steady 200mA current output; outfitted with a 150cm (59") integrated cable.
• Output Logic Integrity: Designed with a highly responsive 3-wire semiconductor framework delivering a PNP Normally Open (NO) switching state; please cross-check your PLC card polarity requirement (PNP) before setup.
• Fixed Diffuse Sensing: Provides a factory-calibrated 10cm (100mm) ±10% unadjustable range; features a diffuse reflective tracking path designed to trigger directly off target surfaces without requiring separate reflector plates.
• Opaque Target Requirement: Optimized to detect opaque objects, metallic sheets, cartons, and solid parts; please note that transparent films or clear glass may fail to return sufficient infrared reflection to trigger switches.
• Reliable Machinery Integration: Compact high-speed object presence limit transmitter perfect for domestic or industrial automated conveyor belt package counting, machinery travel stops, and robotic sorting lines.
