HEIDENHAIN Corporation offers a new generation of rotary encoders with IP64 protection, absolute position-value formation, and functional safety, all within a 35 mm diameter housing size.
These small rotary encoders are known as HEIDENHAIN’s 1000 Series and are designed to be especially useful as single-encoder measurement feedback systems in safety-oriented applications.
HEIDENHAIN’s safety-oriented position encoders with functional safety provide two independently formed position values via a serial EnDat interface. They are certified according to the EN ISO 13849, EN 61508 and EN 954-1 standard for performance level d, safety integrity level 2 and category 3, respectively. The EnDat 2.2 version of these new absolute rotary encoders with serial data transfer offers a single-turn resolution of 23 bits, and a multi-turn resolution of 12 bits. The supply voltage range is from 3.6 V to 14 V.
Eight new rotary encoders round out HEIDENHAIN’s 1000 Series including the ECN 1013, ECN 1025, EQN 1025, EQN 1035, ROC 1013, ROC 1025, ROQ 1025 and ROQ 1035.

Ultra-Slim type 4 light curtain designed specifically with small machines in mind
Introducing a Type 4 light curtain that combines high end performance with an ultra-slim enclosure. The SUNX SF4C series has been designed to offer a machine safeguarding solution without sacrificing productivity. Its size and shape allow for it to fit efficiently into small machinery while maximizing the usable working space for the equipment operator.
Large multipurpose indicator
The bright LED indicators located in the center of both sides of each light curtain can be illuminated green or red by using external inputs. There is no need for setting up a separate indicator, so that equipment is consolidated.
Applications
Slim size for efficient applications
The slim size of the SF4C allows for the available workspace to be increase from the previous model.
IP67 rated enclosure
An IP67 (IEC / JIS) rating is achieved with an ultra-slim size for protection from environmental factors.
Integrated safety input
Contact outputs such as an emergency stop switches or a safety door switches can be connected to the light curtain. This allows for a streamlined output setup for machines that include multiple safety devices and saves panel space which is often a premium in small equipment.
Direct connection of safety devices
Bipolar NPN/PNP output configuration
PNP transistor output and NPN transistor outputs are combined in a single model. This provides universal application worldwide without the need for purchasing separate NPN or PNP models as your project needs change.
Convenient beam axis alignment indicators
The beam channels of the light curtain are displayed in four blocks so that incident light position is shown at a glance. When the beam channel at the bottom most channel (or topmost channel), which is used as a reference for beam-axis alignments, is correctly aligned, the LED blinks red. After this, each block lights red as the beam axes successively become aligned. When all channel beam axes are aligned, all LEDs light green. The display also has a stability indicator (STB) added so that setup can be carried out with greater stability.
Built-in safety control circuit
The light curtain has a built-in external device monitoring function and an interlock function. This allows a safety circuit to be constructed so that a separate safety controller is not needed, and the control box has become smaller to help to achieve to lower costs.
Built-in muting/blanking control function
The light curtain has a built-in muting and blanking functions, which offer advanced functionality when objects passing through the beams while the machine is running. There is no need for a separate muting controller which saves money and space. The muting sensors and muting lamps can be connected directly to the light curtain. Furthermore, the large multi-purpose indicators can be used as muting lamps, which contribute to less wiring troubles, improvement of safety and productivity, and cost reduction.

This compact new safety controller complies with ISO13849-1 PLe and IEC61508 SIL3 safety standards.
The most suitable application of MELSEC-WS is to ensure safe operation of stand-alone machines or systems. To meet your system configuration, it allows you to have additional I/O points of up to 144. Also, you can easily make settings and create logic by using the Setting and Monitoring Tool exclusively provided for the controller.
The WS Safety Controller is programmed using dedicated Function Blocks, and benefits from enhanced diagnostic and communication features when used with EFI-enabled SICK Safety sensors and components. I/O can be expanded with slim-sized 8-in, 8-in/4-out, or 4-out relay modules to control up to 96 safety inputs and 48 safety outputs.
Quickly network the controller to standard control systems like the iQ Platform via Ethernet, and soon CC-Link. Easily replaced Memory Plugs allow users to interchange programs and parameters with ease. The dedicated WS Developer (Safety Controller Setting and Monitoring Tool) software is user-friendly and assists in all steps of development, from system configuration, to drag-and-drop programming, to simulation, and troubleshooting.
