BARTEC 07-6121-9506 Product Description

Overview

BARTEC 07-6121-9506 is the transmitter unit of a Bartec light barrier or photocell sensor pair, used for optical detection in industrial and hazardous area automation. The corresponding receiver models are 07-6121-9507 standard N-switching receiver and 07-6121-9509 inverted P-switching receiver. The 07-6121-9506 transmitter emits the optical beam across the monitored gap to the matching receiver, enabling non-contact object detection, presence sensing, position detection, barrier protection or machine access monitoring where paired Bartec Ex-approved sensor equipment is installed. The device is listed for explosion-protected operation in applicable gas and dust zones according to the Bartec ATEX and IECEx certification data.

Features

BARTEC 07-6121-9506 belongs to the 07-6121-9506 / 9507 / 9509 light barrier family. Its maximum sensing range is 25 m. Power supply is 20 to 28 V DC. Maximum transmitter current is 40 mA, and maximum transmitter power consumption is 1.12 W. Maximum optical output power is 15 mW, and maximum output current is 100 mA. The ambient operating temperature range is -20 to +55 degrees Celsius. The sensor size is 153 x 40 mm with M42 mounting or connection format.

Explosion protection for the installed barrier is listed as II(2)G [Ex op is Gb] IIB and II(2)D [Ex op is Db] IIIA; the complete device is listed as II 2G Ex db [op is] IIB T6 Gb and II 2D Ex db [op is] IIIA T80°C Db. Optical transmission is approved for use in Ex-Zone 1, 2, 21 and 22. Certification references are EPS 14 ATEX 1 696 X and IECEx EPS 14.0042 X. The transmitter must be matched with the compatible 07-6121-9507 or 07-6121-9509 receiver for the intended N or P switching output configuration.

Principle

BARTEC 07-6121-9506 works as the transmitting side of a through-beam light barrier. The transmitter receives DC supply power and emits a controlled optical beam toward the matched Bartec receiver mounted on the opposite side of the monitored opening. When no object interrupts the beam, the receiver detects the optical signal and maintains its normal output state. When an object passes through or blocks the beam, the receiver loses or changes the received optical signal and switches its output to indicate detection.

The receiver output type depends on the paired model: the 07-6121-9507 provides standard N-switching behavior, while the 07-6121-9509 provides inverted P-switching behavior. The optical and housing design is certified for hazardous gas and dust atmospheres, so the sensor pair can be used in Ex-rated machine, process or area-monitoring installations. Alignment, beam path, supply voltage, load current and receiver switching configuration must follow the Bartec light barrier manual and ATEX or IECEx certificate conditions for the installed location.

Applications

BARTEC 07-6121-9506 is used in hazardous-area industrial automation where optical presence, position, object passage, door or access monitoring, conveyor detection, machine guarding or through-beam sensing is required. Suitable installations include chemical and petrochemical plants, oil and gas processing, refining, pharmaceutical production, food and beverage dust areas, paint or solvent handling, grain and bulk material handling, water treatment, offshore or marine equipment, process machinery, packaging lines, conveyors, pumps, compressors, loading bays and machine access openings. In existing Bartec 07-6121 light barrier installations, the transmitter serves as a direct replacement optical sensor spare matched to the original receiver, mounting format and Ex certification.
