Sensor coupling remote display

JSK 42

Advantages at a glance

Sensors provide best possible safety during the coupling process
Increased safety even in poor visibility
A remote display processes the signal and displays it in the driver’s cab

Technical Features

A sensor permanently monitors the connection status
Second sensor controls the position of the king pin
An additional third sensor monitors the contact with the skid plate and increases safety and convenience during the coupling process.
The sensors are located in protected zones on non-moving parts
Electromagnetical compatibility according to highest standards
Also suitable for use in the transport of dangerous goods (ADR)

A = sensor for connection status
B = sensor for king pin
C = sensor for coupling height

* Sensor couplings in the standard version JSK 36, JSK 37 and JSK 42 are complete sets, which means that remote display (SKE501620200) and cable set (SKE002110300) are included in the delivery.

For using sensor coupling versions MB, RT and VT, the truck has to be prepared ex factory for sensors by the manufacturer.

Technical Specification

Sensor coupling system in accordance with the ECE R55-01, TÜ.EGG.095-05, DIN 74081, ISO 3842, ECE R10 directives/standards. Suited for picking up 2” king pins (class G50) in accordance with ECE R55-01, DIN 74080, ISO 337 and steering wedges in accordance with ECE R55-01, DIN 74085.

Explanations:

WA / Maintenance
W = Low-maintenance version
M = Manual lubrication
Z = Prepared for central lubrication
LT1P = LubeTronic 1Point

ZL / Handle length
J = Long handle
K = Short handle

Also available for additional models in the JSK 36 • JSK 37 • JSK 40 • JSK 42 series
