C30

Nafsa Nafsa — Fri, 04 Nov 2022 09:03:05 +0000

Description

This bolt is locked without voltage, the locking is made by an incorporated spring. With an electrical signal the bolt turns to unlocked.

The key has two positions, in the locked position the key cannot be removed. To remove it, it is necesary to unlock the bolt.

Microswitch number and its operation mode (normaly open, coled or combined) depends on the application required.

Applications: it is designed to protect properly from electrical accidents, it is assembled inside the front of the high, medium and low voltage electrical equipment and for all those applications where an electrical signal needs to be sent or turn off by a combined security activation (thumb switch/key turn).

Operation

To operate any part of the line and for being sure that the electrical accident does not happen to people, the bold must be unlocked. Push the (a1) thumb switch, at the same time turn the key 90º to (A), in this position the microswitches (b1-b2) are working and the line of actuation is cut, stop pushing the thumb switch and extract the key (d), this must be kept out of the electrical equipment, in the unlock position the lamp is switched off, it switches on when locking. To lock introduce the key and turn 90º to (B).

ERB35-05/NDBCP

Nafsa Nafsa — Fri, 04 Nov 2022 09:01:10 +0000

Description

This locking bolt is double coil bistable solenoid, where the stroke movement from initial (unlocked) to final position (locked) is made by electromagnetic forces when coil 1 is feeded. The return to initial positions takes place by an inverse polarizing pulse (when coil 2 is feeded) combined with an incorporated spring. It has proximity sensor integrated to detect locked position and free wheel diode to protect the coil against reverse polarity.

They can be manufacturated at any voltage between the maximum and the minimum voltage values shown under chart.
If any variation from the original is needed please contact.
Earthing is recommended if the metallic are accessible.

CU20/CPB

Nafsa Nafsa — Fri, 04 Nov 2022 08:58:29 +0000

Description

Based on CU20/CP model, it is a bistable locking bolt where the movement from initial (unlocked) to final position (locked) is made by electromagnetic forces. The return to initial position takes place by an inverse polarizing pulse combined with external forces or by an incorporated spring.

The bistable solenoid has two working and mantained positions without voltage. One will be held by a permanent magnet system and the other one by a return spring or external forces.

The bolt has a slip with anti-rotation system and frontal, rear and lateral fixations, and the guide has been reinforces for a correct performance in case of radial stress.

*If any changes from the original are needed, please contact.

CU30/CP

Nafsa Nafsa — Fri, 04 Nov 2022 08:56:02 +0000

Description

These locking bolts are simple effect linear solenoids, where the shaft has been reinforces to assure the performance in case of radial stress.

This model assures the locking with voltage (active security).

It has got lateral and frontal fixing.

Its design makes it good to be used in robotics where an intensive work is required.

Voltage under demand: They can be manufactured at any voltage between the maximum and minimum voltage values shown in the chart.
To feed in alterning current the solenoid will have a rectifier mounted in.
If any change from the original is needed, please contact us.

ER30/CCR

Nafsa Nafsa — Fri, 04 Nov 2022 08:51:22 +0000

Description

These latches are single-acting linear electromagnets, in which the shaft guide has been reinforced to guarantee operation under radial stress. This model guarantees locking under tension (active security).

It has lateral as well as front anchorages. Its configuration makes it particularly suitable for use in automation systems where intensive use is required.

Voltage on request: It can be manufactured at any voltage within the range limited by the minimum and maximum voltages.
To supply alternating voltage, the electromagnet will have a rectifier incorporated inside. Faston terminals will be replaced by power cables (L=150mm).
For any variation on the original assembly , please consult NAFSA (see drawing).

ERC30/CP

Nafsa Nafsa — Fri, 04 Nov 2022 08:49:04 +0000

Description

Derived from the ERC Series, and reinforced with a guide to guarantee the operation of the shaft as a latch against possible radial stresses.

The locking is carried out without tension (passive safety). It is suitable for working in automatisms where intensive use is required. It can be fixed laterally or frontally.

*For any variation on the original assembly , please consult NAFSA (see drawing).
