Overview
The Telco SMP-7600-TP-5 is a photoelectric diffuse proximity sensor from the SpaceMasterâ„¢ SM 7000 series, engineered for reliable object detection in industrial automation applications. This sensor combines a self-contained transmitter and receiver in a compact M18x1 plastic housing with a permanently attached 5-meter cable, eliminating the need for additional connectors or wiring complexity. With its straightforward diffuse-proximity architecture, the SMP-7600-TP-5 detects objects without requiring reflectors or fiber-optic cables, making it ideal for general-purpose sensing tasks across manufacturing, packaging, and material handling environments.
Key Features
- Diffuse Proximity Detection: Detects objects up to 0.5 meters without reflectors, ideal for high-contrast backgrounds and varied surface materials
- Integrated 5-Meter Cable: Fixed PVC cable simplifies installation and reduces connection points; 4-pin connector ready for standard industrial wiring
- Dual-Mode Output: Selectable NPN or PNP transistor logic with configurable normally open (NO) or normally closed (NC) switching via integral potentiometer
- Wide Supply Voltage: Operates on 10–30 VDC with built-in reverse polarity protection and short-circuit rated output
- Industrial Durability: M18x1 housing rated IP67, -20 to +60°C operating range, and high tolerance to vibration and electromagnetic noise
- Potentiometer-Based Sensitivity: Onboard adjustment dial enables rapid tuning without external equipment; integral test input for commissioning
