Product catalog summary

Overview of Photoelectric Sensors
Photoelectric sensors, also known as photocells, are electronic devices that use light emission principles combined with electronics. They consist of a light source (emitter) and a receiver. The interruption of the light beam is converted into an electrical signal, which is processed by an electronic circuit. These sensors use either infrared or red light and are available in various types for different sensing applications.

Types of Sensing

Direct Reflection (P Type): The emitter and receiver are close together, and sensing is based on the reflection of light from the object. The sensing distance is influenced by the object's color and surface type.
Reflection with Reflector (R Type): Similar to the P type, but uses reflectors to achieve longer sensing distances.
Polarized Reflection with Reflector (AR Type): Uses polarized light to ensure accurate sensing even with shiny surfaces.
Thru Beam Emitter-Receiver (B Type): The emitter and receiver face each other, and sensing occurs when the light beam is interrupted. This type is suitable for large distances and high-security applications.

FT Series Photoelectric Sensors

FT18SP - FT18SM Series: Cylindrical construction with plastic or nickelled brass housing. Available in 10-30Vdc with NPN or PNP programmable outputs.
FT18EL - FT18 Series: Similar to FT18SM but also available with 20-250Vac supply. Features include programmable outputs and sensitivity adjustment.
FTQSP Series: Compact plastic housing with multivoltage options and relay outputs. Includes indicators for operation and stability.

Technical Specifications

Sensing Distance (Sn): Maximum distance for object detection varies by sensor type.
Light On/Dark On Output: Terminology used to describe the sensor's output state in the absence of an object.
Type of Light Emitted: Solid-state light, either red or infrared, with unlimited life.
Power On Delay: Time between power supply and output activation to prevent false switching.

Installation Recommendations

Ensure sensors are immune to ambient light and properly fixed to avoid beam misalignment.
In disturbed environments, use barrier-type sensors with separate emitters and receivers.
Keep connection wires separate from power cables to avoid interference.

Technical Specifications
The document outlines the specifications for photoelectric sensors in the FT series. Key parameters include nominal voltage, residual ripple, maximum output current, absorption, voltage drop, short circuit protection, interference from external light, temperature limits, and IP rating. The nominal voltage indicates the operational voltage range, while residual ripple refers to the percentage of alternating voltage superimposed on the continuous supply voltage. Maximum output current and absorption detail the sensor's current handling capabilities. Voltage drop is measured when the photocell output is activated. Short circuit protection ensures the sensor resets after a short circuit is resolved. External light interference limits are specified to prevent malfunction. Temperature limits ensure proper functioning within specified ranges. The IP rating indicates dust and water protection levels.

Connection Guidelines
The document provides guidelines for connecting photoelectric sensors in series and parallel configurations. In series (AND logic), all sensors must be excited simultaneously to activate the output, considering voltage drop and absorption. In parallel (OR logic), sensors can independently activate the common output, requiring decoupling diodes. For AC power supply, connections must be made to the same phase, and attention should be paid to total current loss. Suggestions for supplying voltage include using transformers with secondary voltage lower than the required direct voltage and filtering the supply voltage with appropriate capacitance.

Programming and Sensitivity Adjustment
Instructions for programming and adjusting the sensitivity of the photocells are provided. The trimmer adjusts the sensing range, and the switch changes between NPN and PNP outputs. It is crucial not to switch the photocell while powered. A yellow LED indicates operation status, and a green LED indicates stability. The document emphasizes careful handling of the trimmer and switch to avoid damage.

Specifications:
The document describes the features and specifications of photoelectric sensors, specifically the FT18 series. These sensors are available in both plastic and metallic housings and operate within a voltage range of 10 to 30 VDC or 20 to 250 VAC. They are equipped with programmable outputs (NPN/PNP) and offer sensitivity adjustments. The sensors can operate in various modes, including direct reflection, reflection with a reflector, polarized reflection with a reflector, and thru-beam.

Procedures:
The sensors include a trimmer for adjusting the sensing range, which can be increased by rotating clockwise and decreased by rotating counterclockwise. The switch allows for changing between NPN and PNP outputs, as well as turning the relay on or off.

Accessories:
The document details the OT series shutters, which are accessories for M18 emitter and receiver systems. These shutters reduce the light beam to detect small objects, enhancing precision in applications. The kit includes a threaded metal locknut, protection glass, sealing gasket, and a perforated disc.

Technical Characteristics:
The sensors have a maximum output current of 200 mA, a power-on delay, and a switching frequency. They are protected against short circuits and have light immunity greater than 10,000 Lux. The operating temperature range is -20 to +60°C, and they have an IP67 rating.

Recommendations:
Before powering the photocell, it is recommended to program the unit using the switch for the required function (NO or NC). The document also provides guidance on assembling the shutters and the distances achievable for detecting minimum object sizes.

Tables and Data:
The document includes tables indicating the relationship between reflectors and sensing distances, as well as the dimensions and thickness of various components. It also provides model numbers and codes for different configurations of the sensors.

Photoelectric Sensors Overview

The FTQSP series of photoelectric sensors feature a compact design (50 x 50 x 18 mm) with a relay output that is programmable for ON/OFF operations. Sensitivity adjustment is available, and the sensors operate within a power supply range of 12 to 250 VDC/AC. The sensors are capable of direct reflection, reflection with a reflector, polarized reflection with a reflector, and thru-beam sensing. The maximum sensing distances vary depending on the model and the type of reflection used.

FT18EL Series:
This series includes cylindrical sensors with M18x1 housing, offering NO + NC output functions and axial or 90° beam options. They operate within a voltage range of 10 to 30 VDC and have a maximum output current of 200 mA. The sensors are equipped with short circuit protection and are immune to external light interference up to 10,000 Lux.

FT13-CF Series:
The FT13-CF series is designed for detecting non-transparent and translucent materials. These sensors have a metallic housing with a 13 mm fork shape and offer sensitivity adjustment. They support NPN and PNP output functions with NO and NC options.

Technical Specifications:
- Operating temperature range: -20 to +60°C
- IP rating: 65 for FTQSP, 67 for FT18EL
- Housing materials: Grey ABS for FTQSP, Black Makrolon for FT18EL, and Nickelled brass for FT13-CF

Additional Features:
Models with H plug (M12) connectors are available, and delayed models with adjustable delay times on energization and de-energization can be requested. The sensors are equipped with operation indicators (LEDs) for status monitoring.
