CTP and CTA Transponder-Coded Safety Switches with Guard Locking

Product catalog summary

Overview
The CTP and CTA safety switches by EUCHNER combine electromechanical safety with modern transponder-coded technology, achieving high safety standards (category 4 / PL e) according to EN ISO 13849-1 and EN ISO 14119. These switches are ideal for applications requiring high performance levels and locking force.

Versatile Use
The CTP/CTA switches secure safety doors and flaps on machines, suitable for both process and personnel protection. They are designed for harsh environments with high protection ratings (IP65 / IP67 / IP69 / IP69K) and are available in versions meeting ATEX requirements for explosive atmospheres.

Compatibility and Features
The CTP/CTA switches are compatible with existing safety switches, featuring a slim housing, integrated insertion funnel, multiple approach directions, and various plug connectors (M12, M23). They are Industry 4.0 ready, offering communication functions via an EUCHNER IO-Link Gateway, and can be connected in series with up to 20 devices.

Safety and Coding Levels
Transponder coding ensures maximum safety, with options for unicode or multicode evaluation. Unicode evaluation provides high protection against tampering, while multicode evaluation checks for the correct actuator type.

CTP and CTA Features
The CTP features a robust metal housing with a locking force up to 8,000 N, while the CTA offers a robust fiber glass reinforced plastic housing. Both models include optional escape releases and are suitable for various industrial applications.

System Families
The BP system family supports separate operation with real-time data communication via IO-Link Gateways. The BR system family allows series connection of up to 20 devices, providing comprehensive diagnostic messages. The AS system family integrates with AS-Interface for minimal wiring.

Technical Data
The switches are made from reinforced thermoplastic and die-cast zinc, with a mechanical life of 1 million cycles. They operate at ambient temperatures from -20°C to +55°C, with a maximum locking force of 8,000 N for CTA and 3,900 N for CTP.

Additional Information
EUCHNER offers a range of accessories for flexible integration, including mechanical releases, pre-assembled cables, and various mounting options. More information and product catalogs are available on their website.

CTP and CTA Transponder-Coded Safety Switches with Guard Locking-3

n Maximum safety Transponder coding ensures maximum safety. The requirements in all relevant standards can be met with just a single CTP/CTA. Irrespective of whether category 4 / PL e according to EN ISO 13849-1 must be achieved or whether the requirements in EN ISO 14119 must be met – you’re always on the safe side with the CTP/CTA. n Different coding levels Depending on the application, safety switches with unicode or multicode evaluation can be used. For unicode evaluation, the actuator is clearly assigned to the safety switch in a teach-in operation. This ensures excellent protection against...
