Product catalog summary
Overview
The EWS ultrasonic through-beam barrier is designed for contact-free detection of objects, suitable for diverse applications such as detecting bottles or plastic foils. It is available in both cuboid miniature and cylindrical M18 housings, covering a working range from 10 mm to 2,500 mm.

Specifications
- Design: Available in miniature cubic or M18 cylindrical housing.
- Switching Frequency: Up to 500 Hz for fast sampling.
- Operating Voltage: 20-30 V DC with reverse polarity protection.
- Protection Class: IP67 according to EN 60529.
- Operating Temperature: -25°C to +70°C.
- Storage Temperature: -40°C to +85°C.
- Material: Housing made of ABS, ultrasonic transducer made of polyurethane foam and epoxy resin with glass contents.

Functional Principle
The system consists of a transmitter and a receiver. The transmitter sends cyclic sound impulses, which are received by the receiver. If an object interrupts these pulses, the receiver's switching output is activated.

Teach-in and Configuration
The EWS system allows for easy configuration using a button on the cubic model or via Pin 2 on the M18 model. The response time and output function (NOC/NCC) can be adjusted, with an off-delay of 6.9 ms.

Models and Variants
- EWS-15/CD Set: Cuboidal design, working range 50-250 mm, 380 kHz transducer frequency.
- EWS-15/M18/CD Set: Cylindrical M18 design, working range 10-150 mm, 380 kHz transducer frequency.
- EWS-25/M18/CD Set: Cylindrical M18 design, working range 10-400 mm, 320 kHz transducer frequency.
- EWS-100/M18/CD Set: Cylindrical M18 design, working range 100-2,500 mm, 200 kHz transducer frequency.

Electrical Data
- Connection: 4-pin M8 or M12 initiator plug.
- Output: 1 switching output, pnp, adjustable NOC/NCC, short-circuit-proof.
- Response Delay: Varies by model, with filters affecting delay times.

Accessories
Compatible accessories include KST4G-2/M12, KST4G-5/M12, KST4A-2/M12, and KST4A-5/M12.

ews ultrasonic through-beam barrier-3

Ultrasonic through-beam barrier ews for contact-free detection of objects specially in the most diverse applications e.g. with bottles or plastic foils. The through-beam sensor ews is available as a cuboid miniature housing and a cylindrical M18 housing. The ews family covers a working range of 10 mm to 2,500 mm. A through-beam barrier consists of two constructively-identical units which are operated as a transmitter and a receiver. The two units recognize whether they are intended to work as a transmitter or a receiver via the control input. If pin 2 +UB is activated, this unit functions as...

ews ultrasonic through-beam barrier-4

Teach-in The button on the top of the cubic through-beam barrier ews-15/CD allows for a convenient configuration of the response time and the output function (NOC/NCC) of the receiver. The response time and an off-delay of 6.9 ms can be set. At the through-beam barrier in the M18 housing, response time and output function can be set at Pin 2. Two LEDs show the operating state and the state of the switching output of the receiver. You have special requirements? Nothing as simple as that. With us, you can easily find an individual solution.
