Gate and latch controllers


 

ELTRON offers high-quality DOLD safety relays designed specifically for monitoring and controlling gates, bolts and protective covers. Their main task is to secure hazardous areas by monitoring the position of protective elements and ensuring that the machine stops operating if they are opened incorrectly.

DOLD safety relays work with various types of limit switches, position sensors and locking systems, enabling the creation of reliable access control systems for hazardous areas. These devices meet the requirements of standards such as EN ISO 14119, EN ISO 13849 and IEC 62061, making them suitable for use in automated production lines and industrial machines.

The use of DOLD relays for gate and bolt control minimises the risk of accidental contact with moving parts and increases the level of protection for operators and service personnel. Their design ensures high operational reliability, resistance to interference and easy integration with other safety system components.

ELTRON, as an authorised distributor of DOLD products in Poland, provides comprehensive technical support and assistance in selecting relays for specific industrial applications.
