RFID-monitored safety lock with 180 degree actuator

01 December, 2022

The SICK flexLock is a Type 4 safety locking device (according to EN ISO 14119) providing PLe (EN ISO 13849) and SIL3 (EN IEC 62061) protection for personnel and processes through physical locking of moveable safety equipment such as doors, guards and screens to prevent access to, or interference with, machinery in a hazardous area.

Flexible Machine Integration

The SICK flexLock has an open locking head, together with an infinitely variable actuation radius of 180 degrees, which makes for easy and flexible machine integration. This provides a flexible entry point for the actuator, useful, for example, for sliding doors, or doors with small radii. It allows a high tolerance to misalignment, even when a door or gate is sagging. There is a choice of either a flexible actuator with a spring-loaded tongue for when the door guidance is imprecise, or a rigid actuator which allows a side approach to the locking head.

The SICK flexLock’s open locking head and rounded housing make cleaning easy. With its IP67/IP69K housing, the flexLock is resistant to dust and water, making it suitable for tough environments. The three LED status indicators are clearly visible from three sides, enabling maximum machine availability and quick trouble shooting.

RFID Transponder Technology

The safe locking RFID transponder in the actuator offers the highest level of prevention against tampering, saving the time and expense of installing additional measures for manipulation protection. With low and high coded variants available, devices can be selected such that defeating in a reasonably foreseeable manner is prevented (EN ISO 14119). Due to a high locking force of up to 3150 N, the door remains safely and reliably locked until there is no more risk to humans or the production process.
