Process interlocks
What are process Interlocks?
Magnetic locks are used as process locks and prevent process disruptions on machines without a run-down time.
Process interlocks can be equipped with a safety sensor for when they are used in safety applications. As long as there is a voltage on the magnet, the door is locked, depending on the strength of the magnet, the holding force is max. 1200N.
600N or 1200N holding force
Pld according to EN/ISO 13849-1
Daisy-chaining with OSSD
Process Interlocks prevent process disruption
Magnet locks for medium and heavy safety applications
Process locks with RFID and Bluetooth
HoldX process locks are an intelligent magnet lock and RFID safety switch combined into one product with a single connection.
Easily place up to 30 process interlocks in daisy chain without losing the safety function and retaining diagnostic data for each interlock (using OSSD contacts).
Further connecting of the wiring of the switch can be done quickly and easily with the double pigtail connection.
HoldX process locks are equipped with Bluetooth so that the diagnosis can be easily performed via the free App or desktop software.
Holdx smart magnetic lock with diagnosis
Holdx RS compact process interlock
The HoldX RS is a magnetic process lock that is equipped with a contactless safety switch with transponder technology (RFID).
This makes the Holdx RS suitable for use in SIL2 (EN / IEC 62061), Category 3 (EN 954-1) and PLd (EN / ISO 13849-1) applications. The holding force of the magnet has a maximum of 600N.
- Magnetic lock with 600N holding force.
- Extremely durable and wear-resistant.
- Built-in (uniquely) coded RFID safety sensor.
- The unique coded variant is also rechargeable.
- Optionally equipped with a permanent magnet that prevents accidental opening of the door.
- The permanent holding force can be set between 0-50N via the free Bluetooth app or desktop software.
- The magnetic flux is continuously measured to detect contamination on the magnet.
- Great alignment tolerance.
- Daisy-chain up to 30 locks without loss of safety (by OSSD contacts).
- Equipped with status diagnosis by LEDs. and Bluetooth.
- Anchor plate with alignment option.
- Response time of 75ms.
- 8pin M12 plug connection with Pigtail cable.
- Can be used as a highly coded switch according to EN ISO 14119: 2013.
Up to 30 interlocks in daisy-chain
HoldX magnetic locks can be fitted with 2 pigtail plug connections for easy daisy-chaining on machines with multiple access points.
Because the HoldX has built-in OSSD contacts, it is possible to put up to 30 magnetic locks in daisy-chain without loss of safety.
Prevent process disruption
Process Interlocks are the ideal solution for locking doors and hatches that allow access to moving machines with little or no run-down time.
Because the magnet is continuously energized the safety interlock can only be opened after an access request. Opening the process interlock then gives a signal about the safety circuit to the safety controller.
Reaction time
A big advantage of the HoldX process lock is the very short response time of 75 ms. This makes it possible to place the safety device closer to the machine.
Compared to many other common process interlocks on the market (with a response time of 260 ms), the safety distance can be limited by almost 30cm (assuming they have the same run-out time).
Holdx RL heavy duty process interlock
The HoldX RL magnetic process lock is in all aspects the same as the Holdx RS but with an electromagnet that has a holding force of no less than 1200N.
- Magnetic lock with 1200N holding force.
- Extremely durable and wear-resistant.
- Built-in (uniquely) coded RFID safety sensor.
- The unique coded variant is also rechargeable.
- Optionally equipped with a permanent magnet that prevents accidental opening of the door.
- The permanent holding force can be set between 0-50N via the free Bluetooth app or desktop software.
- The magnetic flux is continuously measured to detect contamination on the magnet.
- Great alignment tolerance.
- Daisy-chain up to 30 locks without loss of safety (by OSSD contacts).
- Equipped with status diagnosis by LEDs. and Bluetooth.
- Anchor plate with alignment option.
- Response time of 75ms.
- 8pin M12 plug connection with Pigtail cable.
- Can be used as a highly coded switch according to EN ISO 14119: 2013.
