EUCHNER

EUCHNER CMS series uses magnetically coded actuators that rely on a magnetic field to trigger the safety switch. These are suitable for applications where basic tamper resistance is sufficient. CES series actuators employ RFID technology, which provides a higher coding level and is less susceptible to magnetic interference. RFID actuators are recommended for environments where security against bypassing is critical, such as in high-risk machinery. Both types are non-contact, but CES offers more flexibility in mounting orientation and can be used with door bolt actuators like the BOLT CES-A-C.

EUCHNER M12 single-ended cordsets, such as the C-M12F05-05X034PV10,0-MA-100184, are rated IP67. This means they are dust-tight and protected against temporary immersion in water up to 1 meter depth for 30 minutes. They are suitable for washdown environments in food processing or chemical plants, provided the mating connectors also meet IP67. The PVC jacket offers resistance to oils and coolants, but for continuous flexing applications, the cordsets are designed with a flexing-rated cable construction.

The EUCHNER ESM-BA301 is a safety monitoring relay designed to evaluate signals from safety switches, including those from other manufacturers, as long as the input signals meet the relay's specifications. It has 5 inputs and operates on 24V AC/DC, with a single NC auxiliary output. However, for optimal compatibility and to ensure proper safety circuit performance, it is recommended to use EUCHNER switches with EUCHNER relays, as the wiring and logic are pre-configured for their product line. Always verify the input signal type (e.g., OSSD, mechanical contact) against the relay's datasheet.

The EUCHNER BOLT CES-A-C is a door bolt actuator designed for use with CES transponder safety switches. It provides a mechanical locking mechanism that secures hinged doors in closed position, preventing accidental opening during machine operation. The actuator is compatible with both left and right hinged doors and uses RFID technology for coded actuation. It measures 7.48 inches by 1.57 inches and is typically paired with a CES safety switch to monitor door position and release the bolt only when safe conditions are met.

Selecting the correct EUCHNER actuator depends on the safety switch series and the application requirements. For CMS magnetic switches, use the CMS-M-AB plastic actuator. For CES transponder switches, choose an RFID actuator like the CES-A-BBA or CES-A-BLN-R2-100776, ensuring the door opening orientation (left or right) matches your installation. For door bolt applications, use the BOLT CES-A-C. Always verify the actuator's dimensions and mounting compatibility with the switch housing. 3G Electric provides datasheets with detailed specifications for each actuator to aid selection.

Standard EUCHNER safety switches, such as those in the CMS and CES series, are not rated for explosive atmospheres (ATEX or IECEx). They are designed for general industrial environments with IP67 protection. For hazardous locations, EUCHNER offers specific product lines with appropriate certifications, but these are not listed in the current 3G Electric catalog. If your application requires safety switches in Zone 1 or Zone 2 areas, consult the manufacturer's documentation for ATEX-rated models or consider alternative brands with explicit explosion-proof ratings.
